TCP G43.4

[razmosis]

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

Hi @razmosis 

Thank you for your question. 

It appears that 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.

Best regards,

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.

Thank you!  I was of the understanding that our machine was going to be setup with G93 and that live 4 axis machining would be possible.  I now have a project for it and found that it has G43.4, not G93.  We never use G43.4 in programming so I wasn't sure what it was we had paid for.

I wasn't privileged to the details of the final sale, so it got missed.  Now we are going to have G93 quoted and evaluate if it is worth having.

Thanks again,

Matt

I seem to recall a post elsewhere where G43.4 replaced the need for G93. You might research that.

From what I understood after my conversation with the Toyoda / JTEKT tech, G93 would be required to do what I want to do, G43.4 makes it easier to do accurately.

I've googled quite a bit and don't see any examples of it with G43.4 replacing G93.  I'd be interested in information on that if it's out there.

Thank you!
