Helix bore problem

[Alien]

Hi guys,

Problem is that tool stays down in last hole and not retracts to retract distance.

Only if I use clearance, all works well.

Thanks for any help.

Sincerely,

Michael.

Ok, thanks,but ramp have no ability for finish pass (with different feed).

Additional operation = additional time.

This really is an improper use......

 

Your clearance height and retract height have very different meanings.....and you're trying to make it doing something that it does not calculate in that way.

 

You Clearance height is the approach and retract distance at the start and end of your path.......you have clearance turned off, so the software is doing EXACTLY what you asked it to do......there is not a retract move processed at the end of the path, that is where the clearance move kicks in.......and you don't have one set, so you don't get a move....

Use the path properly and you'll get exactly what you want, this is in my opinion, not a bug, it's a user issue. I would be curious if you sent this in if they would ackowledge it as a bug.
