Would anyone know how to use the G93 Inverse Time Feed Function on a Haas VF3-TR 5 axis trunnion machine? Or any Haas trunnion I would assume for that matter.
Need as much information as possible on the following-
How to properly initiate this in a program.
How to calculate the feed (formulae)
How to proprly disengage within a program.
Thank you in advance.

well im not sure why you need this but what ever you feed rate is the g93 divides it by 60, each line has to have its own feed rate and G94 disingages it wont work with G12,13,70,72,150
individual who perceives a solution and is willing to take command. Very often, that individual is crazy.

We have to use inverse time on our 5 axis abrasive waterjet to achieve smooth contour cuts. The FANUC 150i is not capable of locking rotaries to the linear axis and we would get violent motions.
You really need a software package that will program inverse time because it would take a dozen rocket scientist to program it in 5 axis.
