TCP G43.4

Are any users familiar with using G43.4 to program 4 axis Horizontal Milling Centers utilizing simultaneous 4 axis motion?  If so, can you explain the basics of how you got it to work for you?

 

Thank you,
Matt

The biggest change G43.4 (Tool centerpoint control)  will make to your programming is that you are no longer limited on where the machine coordinate system must be located in relation to your part location. Without TCP, you *must* set your machine coordinate system on the rotation axis of your 4th axis. In addition, without TCP, the machined accuracy of the part is directly correlated with how accurately the part is located in relation to the true machine centerline. 

 

Disclaimer: I don't have a machine with this feature. I have researched it with future use in mind.

 

Here is a good video explaining it. Although made by Mastercam, the principle should be the same in Creo.
