Transform rotate toopath changes Z clearance

[kkominiarek]

1st....still in X5

Horizontal Mach Ctr.

I am transform/rotating 2 operations(machined in planes I created),in these ops the Z clrnc is 392.125 (metric) and cut depth is 335.25.

 

The rotated ops has varying Z clrnc's (392.125, 389.125, 418.85)....why is this???

The Z depths have not changed.

 

Has anyone heard of this before? I have not, I have done countless programs this way and never saw this before.

Are you transforming Drill Operations? What Post are you using?

YES! I have had this happen to me more than once! Ive had my z clearance dive BELOW my part!

The only thing I use transform for is translate. Rotate has burned me in the past (like v9 past...) and I won't even touch transform-mirror anymore (that includes the mirror c-hook). Translate is the only thing I can somewhat trust it to do correctly.

Please send it in to QC[at]mastercam[dot]com.

I just sent it to QC....we'll see what they determine.

[kkominiarek]

one other thing......while "final" Z values did not change....the op takes 2 passes in Z to machine thru the material, the first Z depths at each location do have varying Z depths as well.

[kkominiarek]

The varying Z depths were traced to an operation. The odd part is that the operation did not appear dirty.

During backplot if looking closely....you could see the varying Z depths.

 

W/O the op appearing dirty,there is no final answer as to what caused this or how to prevent it from

happening in the future.

 

Thanks to QC@Mcam and my local reseller Optipro for the help.
