Postprocessor custom drill cycles

Hi there,

I have been struggling with this for awhile but can't get much working...

We have a machine that does not support drilling cycles (Charlyrobot with Mecanumeric CN7000 control), so I am trying to program them via a custom cycle. I have managed to get the standard and dwell cycles to work satisfactorily, but I can't figure out how to program a peck drill.

I have for standard: G00 in the cycle number, plus the following in the box below:
[SEQ_PRECHAR][SEQNUM] X[NEXT_NONMDL_X] Y[NEXT_NONMDL_Y]
[SEQ_PRECHAR][SEQNUM] Z[CYCL_Z+CLEAR]
[SEQ_PRECHAR][SEQNUM] [LINEAR]Z[CYCL_Z-DEPTH] F[CYCL_IPM]
[SEQ_PRECHAR][SEQNUM] [RAPID]Z[CYCL_Z+CLEAR]

which seems to work OK. However, I don't really know how to go about getting the post to output a variable number of pecks, as it seems you would need a variable number of lines or a way to loop through and calculate... Any enlightenment out there?

Thanks, --Mitch

Hello? Not possible?

Only the standard drill cycle can be linearized in the post processor.
You would have to use engraving for peck drilling toolpath by creating a point at the center of each hole. The peck increment can be set as depth/cut.

OK, thanks, I was afraid of that... Interesting workaround with engraving though. --Mitch
