horizontal toolpath issue

[left coast lefty]

When I backplot this radial milling, it does the first two locations fine, then this:

It is a simple 3 pl, 120 deg. apart pattern, but why does it appear to plough through the part? The posted G code looks OK, but I have not tried it yet. X3 with MU1, also does the same on the demo at home.

 

Thanks

This is backplot correct? Do you have the rapid moves turned on?

[left coast lefty]

Yes, rapid moves are turned on, indicated by the red line. If I turn it off you cannot tell there might be a problem.

 

Thanks

Did you transform the path or create planes and program them in that plane?

[left coast lefty]

They were transformed. Also I had rotary axis enabled, and checked 3 axis. The first toolpath the part spun properly, then not so much on the next two. I have heard recently that there are issues with transformed toolpaths, but that was with Mirror which is easy enough to get around. "Rotate" is a necessity.

 

Thanks, Jay.

Do you have your retract set to the right amount. I notice no clearance or retract path.

[left coast lefty]

Retract amount has no effect. In fact I just noticed that if I toggle toolpath display after backplotting, the rapid move line in question disappears.

 

Thanks

Can you share the file?

Jay-

 

I put a similar file on the FTP. Same issue.

i get the same thing in backplot on a HMC it verifies good for some reason its not showing the clearance move for indexing

Simulate axis rotation/substitution checked on backplot?

 

I have had this happen also in backplot, but the code works fine in the machine without gouging. After spending hours checking all kinds of things, I finally went out and ran it and everything was cool.

 

Now, i usually don't worry about it. Try checking the program in the machine. If too long, try simple contour or drill and rotate the same way, pop in the machine and see!

Simulate axis rotation/substitution is checked. I realize that the code works, but if the backplot doesn't work right, they should fix it.

I don't think that's too much to ask.
