Haas st-15y lathe / post processor / too many points in the generated program

Hello there!

 

I need help in the following. We have a quite new Haas ST-15Y lathe, Y-axis, live tooling. I use the latest post processor from fusion library without any modifications.

I want to mill a circle (concentric with rotation) inside and outside of the part with an axial toolholder. In Fusion there are only a few points which you can see in the picture. But in the generated program there are a lot of small "line" movements and not just arc movements. Of course the C-axis "stutters" at these parts of the code, leaves a bad surface finish and moves much slower.

Why is this and how can I get it work correctly? So I can have only arc moves instead of these little line segments?

This is not a real part, just for testing. But I experienced the same behavior at real parts where I had to mill inner or outer arcs.

I'll attach 2 more pictures in the first comment of my post settings.

 

Thank you in advance!

Ah. That's just "the nature of the beast" in regards to how we handle Polar/Wrap milling at this point. Smoothing, as you notice, has no effect on this. Yes, a manually programmed toolpath would be just a few points, but we can't resolve that at this point in time.

Ah, alright. I'm not happy about that. But anyway, thank you for your follow up! 🙂

Best regards,
