Turn-Mill C-axis X-axis interpolation

[taperlength]

I was playing around with this in X8, milling a hex on the end of a lathe part, by interpolating C and X with an endmill parallel to the Z-axis.

The first time, I got G-code output of about 15 degrees per step and then tweaked a couple things and got around 2.5 degrees per line.

Not sure how this was acheived or how to get a specific output.  Any input?

Use C-Axis Face contour, then go into your Misc values page and turn on Polar output

What does Polar output do?

 

I'm looking at my Doosan Puma post Misc values and that option isn't available =(

My best guess on that since nearly every post for a lathe that I have has it.

 

You have an issue with your control def.......maybe accessing the wrong the one, may be mis-listed....

Using non-polar, c-axis output we sometimes break up the movement using "fixed segment length" in the arc filter page. This will make the surface finish much, much better at the expense of a really long program. However your best option would be to use coordinate conversion, if your post and machine support it.

Thanks Cathedral.   Fixed segment length was it.  In the Smoothing section.

 

I'll try the polar output too, JParis.

Can you send me a file and post? I will be more than happy to take a look. There are a few simply things you can do.

The programs i post out for the machine are very long.... the C + X interpolation.  We've managed to get good finish on c-bores using a solid mill holder.
