Excess material

Hello all,

I am learning to use Dolphin and Master5 on a Sherline. Have not really made any parts yet; been cutting air.

Let's say you have a square block of material and want a part machined from the central area. You create the drawing, designate the contour(s) etc in the CAD section. You then invoke the CAM program and generate the Gcode. This code causes the cutter to follow the contour of the desired part. In many or even most cases there is a lot of material outside the contour that is in way of the cutter and interferers with the cutter's path. In other cases the code might ask for an increasing depth or some such that would overstress the cutter or setup. How is this handled? I am aware of the multiple cut/pass settings but wonder about the scrap material interfereance. Thanks,
PJH
