3+2 tilt angle prioritazion


Recommended Posts

We have a Tsudakoma 3+2 5 axis table on our Okuma. The range is -30deg to 110deg.

Why does Mastercam prioritize the -30 deg over the 110deg? Meaning any move or cut that can be done within the -30 range it moves in that direction instead of just utilizing the 110 deg range.

Want to make sure you have a post with Positive output controlled our have it setup the Machine Definition if using a 3rd Party Post to do that as well.

Interesting, I can't find MI9 or Mi10 in my post, it stops at mi8.

And I usually keep the box checked that says "Automatically set to post values when posting" (just out of habit)

All the toolpath was, is a simple 2D contour ramp of a hole,but tilted at an angle using Top/usercreatedplane/usercreatedplane as my settings.

And the operator had the 3 jaw chuck scroll too far out so when it tilted and rotated the scroll hit the table and caused a servo error.

I just changed the angle range in the MachDef to 0/110 so it can't tilt in that direction any more. Not a huge deal I just wanted to find out why.

Thanks guys!

It looks like your Post was built by Postability. They use different MI Values. 

Look at MI5$. Start Solution. The default is '0', which is Negative output. 

Try changing the limits back, and setting MI5 to '1'. (Be sure to force a regeneration when modifying MI or MR Values!)

 

 

Exactly what I think you need to do. You can default mi5 to 1 through the CMD if you want that to always be the option by default.
