Use of G93 in 4 Axis Contouring

[razmosis]

Hello all,

Does anyone have an example of how to use G93 in programming 4 axis contouring work with Creo Manufacturing?  We have a machine with this capability and I'd like to try it.

So far I have been able to get the post to put G93 in the right places, but it puts a F0. for feedrate.

Even if it did work, I am not sure how this really works.  G93 as I understand it interprets feed commands as inverse time.  So if my feedrate in IPM is 100, but G93 is active, the move will occur in 1/100 seconds?  How can that be right?  A short move takes longer than 100IPM would linearly and a long move takes the same amount of time so it moves much faster than 100IPM?

Maybe I am misunderstanding how that works, but that is how I read it.

Thank you for any help!

Hi @razmosis,

Thank you for your question. 

Your post has not yet received any response. I am replying to raise awareness. Hopefully, another community member will be able to help.

Also, feel free to add any additional information you think might be relevant. It sometimes helps to have screenshots to better understand what you are trying to do.

Here is a screenshot of  a post with inverse time set up for an old VF-OE of 90s vintage. Included is some example output. The 15000 feedrate was the maximum the control would take; you should use the largest possible value so short moves aren't longer than programmed. Note that there is a feedrate on each line in G93 mode.  Therefore you won't be able to make changes to feedrate at the machine easily.
