Mr. Machinist has been developed to be the choice of CNC programmers and machinist who need quick solutions to math problems. It also enables the user to edit G
M coded files created manually or by a CAD/CAM program.
With Mr. Machinist you can view a Decimal chart while editing or convert millimeters to inches, get a chord, get the length of a hypotenuse, view and edit multiple machine programs, calculate a bolt circle, calculate
speeds
feeds, and find the area and volume of just about any shape. Do your calculations and assign variables to formulas using the powerful scientific
calculator. You can also strike the F1 key for context sensitive help any time and a library of defined terms will be at your finger tips.
One major advantage of Mr. Machinist is its ability to continually keep a log file of all the functions you choose. This log file is constantly being updated as you require answers to functions. You may view the answer file by striking 'Ctrl-F1' and you may print the answer file by striking 'Ctrl-P'. This answer file, called MRMSOLVE.TXT, only exists during your current session. The answer file is renamed to MRMSOLVE.BAK upon the startup of the next session. u
The full potential of this program can not be conceived with out reading the manual and working with the tutorials.
If you have any suggestions or comments please mail your response to the address below or call the support BBS's at (716) 434-1448 or (716)438-0345. Both boards are 24hrs at 14400. z

Open a file to edit
===================
This will open a file selection dialog box that will display all the files in your current directory. At the top is an input line under the 'Name' designation. You may type in the file name of your choice and then strike 'Enter'. You do have the option of using wild card characters. If you do not know the name of the file you want to edit or the file is in another directory then you have two choices in the method of retrieval.
1) From the file menu select, 'Change Dir'. A directory selection box will appear and you can use the key board or the mouse to highlight your choice, then strike enter or double click with the mouse to get to that directory. Then the 'Change Dir' box will display the files and sub-directories of that particular choice. At that point you can highlight the file name of your choice and strike 'Enter' or double click.
2) If you do not know the name of the file you want to edit then you will have to search for it. If you remember the first few characters of the file name, you could use wild cards to cause the selection box to display only those files that meet your criteria.
Example: RA??.* will show you all files that start with RA and have one or two characters after it and any extension or no extension.

More Help on 'Open a File to Edit'
==================================
If you type a file name in the input line that does not exist and then strike 'Enter', the editor will create and open an empty file for you by that name. You will notice a down arrow symbol to the right of the input line, this is a history list, a list of names you have already used. You have the option to choose file names from it by highlighting the file and striking enter or double clicking it with your mouse. T
Choosing the 'Open' box will load the file you have chosen into a new edit window. {
The file list box is the largest box of the file selection dialog box. This box will show you every file that matches up to your specifications in the input line above it. It will also display the child and parent directories of the current directory. (You can further your understanding of the principles of directories and sub-directories by referring to your DOS manual.)
There are some helpful functions you can use while your in the file list box. One way to get into the file list box is to strike 'Enter' after you have chosen 'Open' from the 'File' menu. Another way is to click on any file name in the box with your mouse. Your 'Tab' key on the key board will cycle you through the many choices of your file selection box in one direction, while holding down the 'Shift' key and then striking 'Tab' will cycle you through in the other direction. The Page Up and Down keys will let you view more files if there are more than can fit in one windows view port. The arrow keys will cycle you through individually.
When your in the file list box you can also type a lower case letter to search for a file name that starts with that letter. If you type a second letter, it will search for the file name with the first letter you typed and the second letter you typed. You can continue this for all file letters or number characters. If you type a capital letter you will search for a directory name in the same manner.
At the bottom of the file dialog box is an information panel. This will tell you all of the information of the file that is currently highlighted. 0

Tap Speeds and Feeds
====================
This menu function in Mr. Machinist will give you the speed and feed of a tap used in a CNC machine that utilizes ridgid tapping. High speed tapping is used widely in the machining industry and it is used with high accuracy. A hole can be bottom tapped within 0.0010 using ridgid tapping. r
Simply input the tap size and you will be given the speeds and feeds for the three main categories of materials. n
Acceptable tap sizes
====================
4-40, 5-40, 6-32, 8-32, 10-24, 10-32, 12-24
1/4-20, 1/4-28, 5/16-18, 5/16-24, 3/8-16
3/8-24, 7/16-14, 7/16-20, 1/2-13, 1/2-20
These are some general speeds and feeds for tapping. This information is general and you can differ from these given speeds and feeds. If you are tapping with a machine that can ridgid tap you can increase the speeds and feeds. Rigid tapping is an excellent method of tapping that can be very accurate. You may also want to multiply your feed by .9 for spring loaded taps to achieve some 'give' in the synchronization of the spindle speed and the machine feed. @

A triangle with a 90 degree angle in it. With two known pieces of information, the solution to all other sides and angles can be obtained as long as one of those pieces of information is a side of the triangle. The three angles added up must equal 180 degrees. :
When you hold down the 'Alt' key and strike the 'T', the Trig. screen will appear. The best way to cycle through the input lines is to strike 'Enter'. If you happen to put the maximum amount of digits (12) into the input line then you will be automatically cycled into the next input line. When you have your two pieces of information entered you may then hold down the 'Alt' key and strike 'O' for OK or you may strike 'Enter' until you have reached the OK button and then strike 'Enter'. You may also use the up and down arrows to move up and down the dialog box.
The 'Tab' key cycles you through the dialog box in one direction. If you hold down the 'Shift' key and then strike 'Tab' you will cycle through the dialog box in the other direction. Y
The Perpendicular Line calculation that is given in the answer box is the distance of the line that extends from the intersection of the side opposite and the side adjacent perpendicular to the hypotenuse. This distance is sometimes needed when a milling machinist must put a part up on an angle in a vise in order to machine a chamfer on it. '

Climb Milling
=============
Refers to a milling cutter that is 'climbing up the wall' of the cut just like to two gears meshing together. This type of machining is often used for a good surface finish but not when there is a lot of stock to be taken. 3
Conventional milling is the opposite of climb milling and should be used most of the time. Many forces come into play when a milling cutter is doing it's job. A small and long end mill will 'whip' in the bottom of a cut and flex into or away from a wall depending on the type of milling being performed.
When a mill cut is going to remove a slug, this type of cut could cause the slug to be 'sucked' into the tool and therefore create a major boo boo!

You may open and manipulate many edit windows at the same time, cut and paste text to and from any window. If you like, you can open the same file more than once for reference purposes. If you want to reference some code from another CNC program you can bring the file up into an edit window, resize it and cut and paste from it to your current CNC program. In doing this you could create a type of 'database' for your machine files.
Let's say you have a machine file, (CNC program) called K0154.TXT. You could create a file called K0154N.TXT for the 'notes' to this file. In K0154N.TXT you could put the job number, cycle time, tools used, set up notes and what ever you like! Then when it comes time to look at that CNC program you could call up these two files, resize them to a smaller size and look at both of them!
When it comes time to save your changes, strike F2 and it's done. You'll know that you have made a change to the edit window when you see a little star '*' just to the right of the lower left edit window. If you strike Alt-X to quit when the star is there (you have not saved your changes) you will be asked if you want to save your changes. At this time you can strike 'Y' for yes or 'N' for no or 'C' for cancel. Whenever you save a file, Mr. Machinist will keep your old one and put a BAK extension to it.
Let's say your editing a file called README.TXT and you make a few changes to it and then you save it. You will now have 2 files on your system by that file name but with different extensions, README.BAK and README.TXT.
Do remember this though, if you make a save and a README.BAK exist, the old README.BAK file will be replaced by the newer README.BAK file. Please note that README.BAK is used here just as an example!
Using a Mouse
=============
It's faster for a user to use the keyboard instead of the mouse, but when it comes to resizing and moving windows, the mouse is the preferred method. The left mouse button is the one you'll always use. Just point and shoot! Pick a menu, click the left button and down comes a menu. Chose from the menu and click for results. To move around edit windows, 'drag' the mouse on the edit window heading. Dragging the mouse means to hold down the left mouse button while moving the mouse. When you want to resize the current window, drag the mouse on the lower right corner of the edit window. To highlight a block of data while editing drag the mouse over the text you desire to mark and that text will become highlighted.
The editor incorporated into Mr. Machinist can manipulate a file of 65 K or under. That is the limit at this time. If you want to edit a very large file you will have to use a more powerful editor or 'split' your file and then 'paste' it back together.
The editor in Mr. Machinist has the capabilities to edit almost all CNC programs. If the CNC program is larger than this limit then maybe you can create a smaller program by using sub-programs. A small CNC program that does a lot is the sign of a good program!!!
This editor is a standard editor that uses commands that are universal in most programs. A small book can be created telling you how to be proficient in using an editor but here are some basics.

Chord, Volume, and Area of a Spherical Sector
=============================================
In the input box you must enter the Radius and Height while in the spherical sector menu. While in the spherical 'segment' menu you must enter the height and one other input, either the radius or the chord. The height can not be greater than 2 x Radius! You will then be displayed an answer box giving you the chord, volume, and area of the spherical sector. z
A sphere is a closed surface where all points are the same from a given distance. Another simple name for a sphere is a ball. A spherical sector is a section of a 'ball' or sphere that is cut out from the whole part. It consist of a full revolution and not just a segment. A spherical segment is a cut section from the 'ball' or sphere but it is cut at two parallel lines. k
Formula (Spherical Sector)
============================
V = Volume, A = Area, C = Chord:
V = (2 x pie x Sqr(radius) x height) / 3
A = pie x radius x (2 x height + .5 x chord)
C = 2 x Sqrt(height(2 x radius - height))
Formula (Spherical Segment)
=============================
V= pie x Sqr(height) x (radius - height / 3)
A= 2 x pie x radius x height
C= 2 x Sqrt(height(2 x radius - height))
R= (Sqr(chord + 4 x Sqr(height))/(8 x height)

Resize and Move Windows

There are two windows that can be resized, the edit window and the help window. All windows can be moved. Learning to resize and move windows at a good pace can really speed up the job of multiple editing and/or viewing multiple formula answers. ,
Using the mouse is the quickest way to resize and/or move a window. To resize a window using the mouse, 'drag' the mouse on the lower right corner of the window. To 'drag' the mouse means to hold down the left mouse button while you have the mouse cursor positioned on a certain item. As you hold down the left mouse button on the lower right corner, begin to move the mouse around. You will now see that the window resizes from the lower right position. The window will stay at its current position as soon as you take your finger off of the mouse. e
To resize a window using the keyboard, you hold down the 'Alt' key and then strike 'W'. This will pop down the 'Window menu'. Strike the 'R' key to resize a window. After striking the 'R' key you can use the arrow keys to resize the window. When you have the window where you want it, strike the 'Enter' key. This will take you out of the resize mode.
To move a window using the mouse you drag the mouse on the top heading of the window. The top heading of a window is the wording that is centered on the top line of the current window.
To move a window using the keyboard you should hold down the 'Alt' key and then strike the 'W' key and the 'Window menu' will pop down. Then strike the 'M' key and you will be able to move the window using the arrow keys.

Once the calculator window is on screen you will be ready to enter your calculation or formula. You can strike the 'Tab' key to move around the calculator dialog box. Striking the 'Tab' key will take you to the 'Ok' button, once more will take you to the 'Cancel' button and once more will take you back to the input line. If you hold down the 'Shift' key and then strike 'Tab' you will move around in the opposite direction. You can also use the mouse to click on one of these three items and activate them.
Once your in the input line you can start to enter your data. When numerical entry is complete you may strike 'Enter' or click on 'Ok' with your mouse or strike 'O' for 'Ok'. ,
Example: 4+4*87/456*tan(56) then 'Enter'.
The order of precedence is at work here. The calculator evaluates the parts of an expression inside the most deeply nested parentheses before anything else. In the example, the tangent of 56 is calculated and then 87/456 is calculated, then the two are multiplied and 4 is added.
Upper and lower case input of functions are treated the same. You may also append an O for octal or an H for hex after a number. If you input 55o, your answer will be 45 because 55 in octal is 45. If you input 640H, your answer will be 1600 because 640 in hex is 1600. When you type a hex constant you must be sure to type a number before it. If you type FF for a hex number then you will get an error, but if you type 0ff then you will get 255. (
You may enter assignment statements such as, a:=3, and b:=3, and also c:=sqrt(a*b). Always use a single character as your variable, A to Z. If you use assignment statements within expressions always be sure they are predeclared. Here is an example using the formula for RPM (R) of a spindle: a
12 x F (Feet per Minute)
R = --------------------------
Pi x D (Diameter of Endmill)
You would enter f:=200 and then strike 'Enter', d:=0.5 and 'Enter', and for the end result, r:=(12*f)/(pi*d). If you were to leave out the parentheses your result would be in error due to the fact that the calculation would divide first and then do its multiplication.

Wire Cut E.D.M.
===============
Wire cut E.D.M. is an electrical discharge machine utilizing a numerically controlled movement and a wire electrode to machine a workpiece to a desired contour. The electrode is is a brass or molybdenum that varies in a diametric range of .002 to .014.
The workpiece may be of any material as long as it is conductive. Hardness does not adversely affect the E.D.M. process, but the capacity for the workpiece to conduct heat and electricity do.
One terminal of the power supply is connected to the electrode and the other to the workpiece. The electrode and workpiece are held in close proximity by the machine, yet they always remain separated by a small gap.
The gap is always filled with a circulating dielectric fluid, usually deionized water in wire cut E.D.M., which acts as an insulator. The dielectric also cools the electrode and workpiece and flushes away the eroded metal particles from the surface of the workpiece.
When the voltage from the power supply is first applied across the gap the insulating characteristics of the dielectric prevent the current from flowing. An electrical field is established at the shortest distance between the electrode and the workpiece, the conductive particles form a "bridge" in the direction of this field. When the gap is narrowed, the voltage of the electrical field causes the bridge to ionize, an ionized gas channel forms, this is the point at which the current begins to flow.
High temperatures and pressures are generated melting and vaporizing a small section of the workpiece. This current continues during the "on time" of the pulse and turns off during the "off time" of the pulse.
During the "off time" the voltage drops to zero, so the current ceases, causing the ionized channel to collapse, and heat and pressure dissipate. z
This implosion ejects the melted particles into the dielectric, producing a small cavity in the workpiece. The ejected material is solidified into a small hollow sphere and washed away by the flushing action of the dielectric. Although most of the molten metal is carried away from the workpiece, a small amount is resolidified and is commonly referred to as the recast layer.
The size of the cavities produced by the process is directly proportional to the amount of current used. A low current produces a fine finish, and a slow cutting speed, and higher currents produce a rougher finish, and faster cutting speeds.

Vise Information
================
One of the most commonly used vises in the machine shop is the 6 inch vise. Many different forces are being dispersed when a vise is tightened. The part you are clamping must be aligned and indicated in. The more time you spend setting and indicating in your vise, the better the end result will be.
One common problem with some vises is that after a few uses the movable jaw can become loose and increase in play. In some vises their is an adjusting cap screw in the middle of the back of the movable jaw. By tightening this cap screw you can minimize the amount of play.

File Menu
=========
The file menu brings down a menu full of choices that have to do with editing and printing files. This menu also has the change directory function which helps you search certain directories without typing in full file names. v
There is also a Dos Shell function within this menu that 'shells' you out to DOS. To 'shell' out means to leave your program temporarily and go into DOS so you can execute other programs. Keep in mind that when you do this, Mr. Machinist still takes up a little memory so do not try to execute a program that uses a lot of memory or you will not be able to execute it. To get back into your program after shelling out type 'EXIT' at the DOS command line. One thing you can also do to make DOS shell easier is to write a small batch file so that when you strike E a batch file called E.BAT executes and gives the command EXIT.
The last command in the file menu is the Alt-X command. This command will exit Mr. Machinist. Strike it any time to exit the program. If your editing a file and you have not saved it, the program will ask you to save it before exiting.

The 'New' command will bring up an edit window with no title. At that time you can start editing a new file. If you want to save it you can bring up the file menu and choose 'Save as' or 'Save'. Either way you will be asked to give the file a name because it does not have a name and it needs one. If you try to 'Exit' the program without saving it you will be asked if you want to save it or not. It's always a good idea to save the file your working on about every 5 minutes or so.

Save
====
The 'Save' menu will save a named file to your disk. You will be asked to give the file a name if you try to save an un-named file. You must be editing a file before this can be active. If your editing a file that is already named, the 'Save' command will save the file without showing you a thing. You'll see your hard drive light come on if your saving it to the hard drive or you will see your floppy lights light up. ?
The fastest way to save a named file is to strike the F2 key!

Mr. Machinist Text Files
========================
The Mr. Machinist program can create, edit, and delete three different files on your hard drive upon each execution. 0
MRMSOLVE.TXT, MRMDRILL.TXT, and MRMBOLT.TXT.
MRMSOLVE.TXT
============
This is a file that is created and deleted each time the program is executed. It holds all of the answers to each function except drill speeds and feeds and bolt circle calculations. This file can be viewed and printed at any time. Holding down the 'Ctrl' key and then striking 'F1' will let you view this file and holding down the 'Ctrl' key and then striking 'P' will print this file.
MRMDRILL.TXT
============
This is a file that is created only when you choose the drill speed and feed function. It holds all of the answers to the drill speed and feed calculations. This file can be viewed and printed at any time. Holding down the 'Ctrl' key and then striking 'F4' will let you view this file and holding down the 'Ctrl' key and then striking 'T' will print this file.
MRMBOLT.TXT
============
This is a file that is created only when you choose the bolt circle calculation function. It holds all of the answers to the bolt circle calculations. This file can be viewed and printed at any time. Holding down the 'Ctrl' key and then striking 'F8' will let you view this file and holding down the 'Ctrl' key and then striking 'F9' will print this file. =============================================================== o
All of these files get deleted or 'cleaned up' after you exit the program. If you would like to save these files in order to edit them later or have them available for information then you must rename them before you exit the program. You would do this by bringing them up in the editor and choosing the 'Save As' function. If for some reason the files do exist on your drive when you first execute MRM (Mr. Machinist) the program will detect this and ask you if you want to delete them or leave them alone. If you do not delete them then the new information will be appended or 'added' to the already existing files.

Factor
======
The factor of an integer is also called the divisor of an integer. 45 is a factor of 3510 because 45 * 78 = 3510. To test if an integer is a factor of another integer you divide the integers and then check an see if there is a remainder. If there is a remainder of 0 then the integer is a factor of the other integer.

Broaching
=========
A type of process used in forming symmetrical or irregular, grooves, or slots in machined parts. The broaching process is rapid, accurate and also leaves a good finish. Broaching is usually used to cut keyways, machine round holes to square, hexagonal, or other shapes, forming splined holes, and for a lot of internal operations. Z
These types of tools are usually long shanked and taper to the finished size at the top.
ENTER

Backup Files
============
Using this option you can choose to create or not to create backup files. Backup files are created with the file extension .BAK by default. M
When you edit a file that exists on your drive, that file is actually in two places: On your disk or drive, and in the RAM of your computer. When you first create a file, it only exists in RAM until you save it to disk. When you save a file to disk or drive for the first time it exists with the name that you chose to give it. Mr. Machinist will create a backup file by default when you save a file that already exists on your disk or drive. You can choose to shut this feature off therefore saving on disk space but loosing the chance to have a file that has not been over written.

N Sequence Numbers
==================
A sequence number is usually the first word that appears in a block or sentence of a text file for CNC machines. There are two main reasons behind a sequence number. K
1) Lets the operator know which line the machine is currently processing. E
2) Provides the operator a way to search or find a particular line.
These sequence numbers usually go to four digits and begin with an N. The very first line of a CNC program or 'text file' always begins with an O on the CNC machine but not always in a file on a personal computer. B
Here is an example of a G and M code file with sequence numbers:
:0203 (05-07-93)
N0005 (ARM-ROCKER)
N0010 (123456 JOB#1234)

Clear Your CNC's Memory
=======================
Some machine shops have to download there CNC files to a personal computer in an office some where. Many shops now are supplying there workers with computers right on there bench near there machine. As a CNC's control gets filled with programs it can become full and cause the operator to have to download one or more programs to make memory enough for the current program to load.
Many CNC controls offer a function that lets them download ALL files in the CNC's memory to ONE file on the personal computer. This is the fastest method of clearing the CNC memory. There is just one big problem that people face when they have this huge file on there computer with many programs all in one file! They have to manually cut and paste to get even one program back to the CNC. d
Mr. Machinist has a one of a kind function in it that can 'split' a large file that has been downloaded from a CNC. The purpose of this function is to rewrite ALL of the individual programs to seperate files on the personal computer and they are named by there four digit program number just as they were on the CNC with an additional extension of .TXT.

Split
=====
The main purpose of this function is to 'split' a large text file that was downloaded to a personal computer by a CNC machine into all of the original seperate programs. You would have to manually cut and paste using an editor to do this if you did not have this function to work with and that would take a lot of time and money!
Mr. Machinist will ask you for the file name of the large text file and then it will look for the first occurance of a line that starts with a ':'. Once it finds the colon Mr. Machinist will get the next four digits and add an extension of .TXT to it and give the new file the proper program number. It will then begin to copy every line after the colon to the new file until it reaches a blank line.
Once a blank line is encountered the program will look for the next occurance of a ':' which should be the next line. At that time the same process occurs until every file is written to the specified directory.
If the file name should exist in the directory already then a message box will appear letting you know that the file does exist. This information will also be sent to the MRMSOLVE.TXT answer file. You will have to delete the file that exist in order to rewrite it. z
After this process is complete, the original large file will still remain for you to decide what you want to do with it. %
One little note:

A good CNC programmer should know a lot about DOS. Read manuals carefully and study to show thyself approved!

N Sequence Number Removal
=========================
The Mr. Machinist program has a function in it that can remove N sequence numbers from a CNC text file on your computer. You will be asked for the name of the directory and file that you want the N numbers removed from and the new file name. If the new file exists on your drive you will be shown an error box and then you will start the process over. If the new file name is the same as the old file name you will be prompted to verify the write over procedure.
It is advisable to give the file name a different name so you can view the way it was un-sequenced and not be afraid of loosing the old one. l
The removal function will un-sequence every line except lines that do not have N sequence numbers in them.

N Sequence Number Insertion

If there are already scrambled sequence numbers in the file it would be wise to remove the sequence numbers using the remove function and then re-sequence the file using this function. Q

Choose a file to sequence
=========================
This will open a file selection dialog box that will display all the files in your current directory. At the top is an input line under the 'Name' designation. You may type in the file name of your choice and then strike 'Enter'. You do have the option of using wild card characters. If you do not know the name of the file you want to sequence or the file is in another directory then you have two choices in the method of retrieval.
1) From the file menu select, 'Change Dir'. A directory selection box will appear and you can use the key board or the mouse to highlight your choice, then strike enter or double click with the mouse to get to that directory. Then the 'Change Dir' box will display the files and sub-directories of that particular choice. At that point you can highlight the file name of your choice and strike 'Enter' or double click.
2) If you do not know the name of the file you want to sequence then you will have to search for it. If you remember the first few characters of the file name, you could use wild cards to cause the selection box to display only those files that meet your criteria.
Example: 03??.* will show you all files that start with RA and have one or two characters after it and any extension or no extension.

If you type a file name in the input line that does not exist and then strike 'Enter', the editor will create and open an empty file for you by that name. You will notice a down arrow symbol to the right of the input line, this is a history list, a list of names you have already used. You have the option to choose file names from it by highlighting the file and striking enter or double clicking it with your mouse. If you wanted to begin to manually create a CNC program then you would start this way. T
Choosing the 'Open' box will load the file you have chosen into a new edit window. {
The file list box is the largest box of the file selection dialog box. This box will show you every file that matches up to your specifications in the input line above it. It will also display the child and parent directories of the current directory. (You can further your understanding of the principles of directories and sub-directories by referring to your DOS manual.)
There are some helpful functions you can use while your in the file list box. One way to get into the file list box is to strike 'Enter' after you have chosen 'Open' from the 'File' menu. Another way is to click on any file name in the box with your mouse. Your 'Tab' key on the key board will cycle you through the many choices of your file selection box in one direction, while holding down the 'Shift' key and then striking 'Tab' will cycle you through in the other direction. The Page Up and Down keys will let you view more files if there are more than can fit in one windows view port. The arrow keys will cycle you through individually.
When your in the file list box you can also type a lower case letter to search for a file name that starts with that letter. If you type a second letter, it will search for the file name with the first letter you typed and the second letter you typed. You can continue this for all file letters or number characters. If you type a capital letter you will search for a directory name in the same manner.
At the bottom of the file dialog box is an information panel. This will tell you all of the information of the file that is currently highlighted.
