unifield 5 axis tool axis control

[ken wong]

Hi everyone!

I want to machine bronze color surface using 4 or 5 axis machine. how to control tool axis in order my tool always normal to gray surface 

thanks files attached

Ken, here you go. I used tool axis control lines rather than the gray surface. Also, If you're planning on running this code on a trunnion you will most likely get extreme c axis rotations. You could use the transform rotate function to skew the part a bit or instead of using tool axis control lines use the "from point" or "to a point". One of those to functions should help you control the trunnion. Let me know If I was wrong, thanks

In 2023, there's an option that's perfect for this called "tilt relative to reference surface."  See the attached picture.

For this part in 2022, I'd set it to rotate around axis, with an angular limit around z of +5 to 185 so it doesn't go vertical and cause your C-Axis run away (called Singularity)  as DBronson points out.

Thank you ,  DBronson

I will try tomorrow on machine

in 2023 is perfect toolpath i look for

[gcode]

Yes...  MC2023 does a really nice job of this

I ran the MC2023 version of this file through our Postability Haas V6 - TR210 machine sim and it ran perfectly

If you didn't go crazy on the feed rates this toolpath would run very well on this machine

Wow, "tilt relative to reference surface" is a great function! It's almost to easy to do.

yes I was trying to fix that toolpath in 2022 and feeling really stupid

I did not realize that it was new to 2023

It's so great, we made no less than three videos on it for 2023!
