Description:
This is a calculator that I wrote for OMAX Corporation to test some routines to include in their CAD / CAM software. It has proven to be very popular. This calculator is now offered as "Free ware" to anyone who wants to use it. Note: OMAX still owns the copyright, and you do not have permission to modify it, or re-sell it, but you do have permission to give it to your friends. Note also that this is an older version than what is available to download from the OMAX web site for OMAX customers.
Above: the calculator
"squished" so that it takes up minimal desktop space. you can
even make it smaller, if you like.

Abrasive-jet Feed rate Calculator: ABRCALC.EXE: (Updated 5/31/2003)
Computes fastest LINEAR feed rate to cut through a given material, and a slower linear rate for general machining. (Using Dr. Jay Zeng's Doctoral thesis for the cutting model). It's very simple, but it will give the novice a good idea of how fast an abrasive jet can machine stuff.
I should point out that it gives linear feed rates, which can be misleading. It is very important when actually cutting that you also consider that feed rates must be varied to compensate for the geometry of the part. I.e. if you are cutting around a curve or corner, you must slow down significantly to insure accuracy of cut.
Feedback and suggestions are much appreciated!
