I am working on a post for a 5 axis D-head, A-table machine.
The program drills many holes at an angle while rotating the table.
I had to use the rotate ude to get it to start with the head tipped to the left the way I want.
When I do this though, the A table does not use the shortest solution for the table when it crosses over A zero.
Setting limits on the fifth axis in PB has no effect.
Using the negative A is the shortest solution. Not sure why it uses the other solution.
This what I want.
N609 X0.1207 Y-2.6452 Z0. A1.2521 D-145.0
N610 X-0.1962 Y-2.643 Z0. A-2.0359 D-145.0
This is what I get.
N609 X.1208 Y-2.6452 Z0.0 A1.2542 D-145.0
N610 X-.1963 Y-2.643 Z0.0 A357.9622 D-145.0 <- big unwind
And the big unwind only happens when I use the rotate ude.
Go to Solution.
Just to make sure...
What are your "A" axis limits (not sure if 4th or 5th axis)?
If "0 to 360", then I expect what you got
if "-360 to +360" (or other minus to plus values) then I would expect to get what you want.
Note if you are doing IS&V, the machine tool definition limits over-ride the post's limits.
Production: NX10.0.3.5 MP16/TC11.2I'd rather be e-steamed than e-diseaseled
You saved the day.
I have +-360 in PB. A is fifth.
It was the limits in the mcf.
Forgot to re-load my machine after changing the limits in the mcf.
