Inverse Feed Rate G93 in Mach3

Description of the problem:

Confusion on how to use inverse feed rate.
 

Solution:

Inverse feed rate is good for use when using rotational axes. It uses a different input for feed rate instead of the standard units/min F word that is used in normal G94 moves.
 
To calculate it use the following equation:
 
[Inverse Feed Rate] = [Desired Feed Rate (in/min)]/[Distance (in)]
 
However, if doing an arc (G02 or G03) use the following equation:
 
[Inverse Feed Rate] = [Desired Feed Rate (in/sec)]/[Distance (in)]
 
It is an odd quirk of Mach3.
