Hello,

I am not sure why Cambam calculats for my pocket operation not the right toolpath.
The problem is that i want to cut a pocket with a 6mm diameter tool. When i choose a step over of 0.6 Cambam generates a toolpath that
did not cut the whole "middle". Between two pathes there are 6.88mm distance ...

I will give you three examples:

0.6 step over (distance between the two lines in the middle is 6.88mm)

Attachment 268894

0.5 step over (distance between the two lines in the middle is ~2mm)

Attachment 268898

0.7 step over (distance between the two lines in the middle is 5.54mm)

Attachment 268896


So my question is: Why does Cambam does not add a toolpath in the middle like it does for step over 0.5? 6mm tool and 6.88mm distance between pathes?

Thank you!

The first tooth path is the cutter radius away from the wall. Then each successive cut is taken at Stepover * cutter diameter in from the last cut until there is no room left to step. So a step over of .5 would mean the cutter moves in 3mm. I haven't gone thru all the combinations but I don't think there is a step size that would result in leftover material in the center (a gap of >cutter radius).
