I did an interesting exercise today. I received a DXF from the cam grinder with 360 line segments. I imported into SheetCam and then exported it to GCode.
I looked at the GCode and couldn't believe my eyes. It was only 7 arcs long. SheetCam must have joined the lines together and created arcs. So I plotted the arcs against the original DXF. Most of the arcs were very similar to the original and the greatest error was 15 thou. (this is on a 3 " disk) Most sections were under 1 thou out. I reckon it would be almost perfect with 14 or so arcs. I have posted a similar question on SheetCams forum but does anyone have a DXF line to arc converter where I can enter the maximum error acceptable and it comes out with closest arcs? Surly the grinding head would be a lot happier and smoother with 14 or so arcs instead of 360 line segments.
