Hi all

 

[S:B:C]

1.Remove your lead in and lead out motions from the costumize dialog, and add lead in / out within the "automaticcut" using the build cut dialog, Then simply add start hight, and hight.


2. modify the parameters to include following options "lead _radius" "tangent_lead_step" "normal_lead_step"and "cutcom"

Hi Leow,


in Trajectory sequence > Customize > Automatic Cut > Redefine > Build Cut > Approach (Exit) > Lead In (Lead Out) . For many depths select Cut > Start Height and Height.


Best regards.

Dear friends...

Thank you friends for spending your time for me...
Basically it was the one I was looking for...
But one problem still remaining is that about compensation

When I post the same file that S: B: C made for me... in in my program I could not find any G41, Dvalue for compensation and G40 for compensation Cancel

Hi all:

I tried to post the same programme S:B:C posted here..
but no effect.

I manage this with a SITE file.
The following options create the effect I "think" you want.

Corner_passes all_passes
RETURN_TO_START ALL_PASSES
END_OVERTRAVEL_PASS ALL_PASSES

Sample of output using these options.
Profile cut. I get the same result cutting boss or bore features. I input the lead in / out, cutcom, etc, data with the rest of the parameters on the main parameter page. I don't have to drill down so far to get the result I am looking for.

This may not be what you have in mind. Picture of toolpath is attached.

Best regards,
Sean

hi

Thanks for the reply

Which type of sequence you are telling

I never come across these options in parameter for any sequence setup

Leow,


Several people responded with what you were asking as far as the required toopath. If I understand, I think the only outstanding issue is teh G41.


1st, make sure your NCL file contains CUTCOM statements. If not, setup the sequence parameter CUTCOM=YES. This should output CUTCOM statements for you in the NCL file.


The rules for CUTCOM in Pro/NC are as follows:


Every cut must have a known linear approach and a known linear exit. Aproaches/exits can be formed in any way feasible in pro/NC, such as parameters, build cuts, ends, tool motions, etc. But, you must have both the approach and the exit. If they areboth present, you you get a CUTCOM on the1st linear approach move, and cancel on the last linear exit move. Otherwise, you will see a warning, and no CUTCOM.


Hope this helps.

Dear friends.

Thank you very much for your support..

I got it..

Of course, do not forget to set the sequence parameter CUTCOM ON, as well as a D register.
