Can you turn off clerance plane for single features

January 21

Hi,

I’m currently working on a program for a part that exceeds the machine’s volume in certain areas. For these sections, I need to create precise and delicate travel moves to navigate inside the part without issues.

For three specific features, I’d like to completely disable the automatic clearance travel moves—essentially achieving the effect of using "No Generating" in CNC-Start—and instead handle all travel moves manually via PCM. For the remaining features, I’d prefer to retain the default automatic travel movements.

Is there a way to achieve this flexibility?

Best regards

Hello,

as far as i know it is not possible, i had a similar problem a couple of years ago with an enormous part on a MMZ. We made the "clearance plane" in the particular area smaller so that the actual part was out of the "clearance plane" and blocked those edges.

Another way would be to create far out reaching stylus probes.

But maybe someone knows a more elegant solution.

Careful use of Sub clearance planes that have no value in "Retract to inner plane" in combination with PCM and Block Edges will probably work. If you have multiple features in a row on the same sub clearance plane, the CMM will not move to the parent plane inbetween the features.. We've done it. In that program I had to also use PCM to create dependencies so all the features that were at the limit always ran together and in the same order ( Just using a getActual().comment is enough).

Yes it is possible to have no clearance moves and use "position points" only.

Chris, could you elaborate how its possible?

You could add position points within each feature. On the Run screen you will choose Use Position Points Only, instead of Clearance Planes.

UNDERSTAND: that you can’t reorder the features without correcting/ updating the position points, and you must always run with position points. If you hand this program over to an operator they must run from position points only.

Yeah, without making it more complicated than it needs to be, position points most likely your best bet.

Maybe irrelevant to your specific need and you may already know it (some don’t), but you don’t have to move to a clearance plane at all moving between features. You can choose nothing in the clearance drop down menu if you don't have other features to move around.

It doesn't say/show "nothing" , I just put that in the illustration below to show the empty spot.
