3 IDENTICAL HOLE POCKETS, WHY DIFFERENT MACHINING STRATERGIES?

[Fabbunny69]

Hi All,

Strange problem I cant resolve, help would be much appreciated.

In the attached file there are 3 identical holes and I am using 2D pocket to machine them. One is being spiral milled(what I am after) and the other two are circle milled. Its the same toolpath, any ideas why this is happening?

This is an old bug that still hasn't gotten any attention (CAM-18607 for reference). Why it does this is not known to me...

The best solution I can offer is this: program a toolpath on the pocket that has the spiral result. Put that into a Pattern > Duplication folder and select the correct points:

 

At times, you MAY need to create some sketch geometry (circle center points) to get this to work optimally

Thanks @seth.madore 

At least now I know its something that requires a work around, hope it gets ironed out one day.👍
