Rex Swensen's Web Site The CNC Computer Program

The traditional approach to CNC is to make a CAD drawing and program the cutter path graphically on the drawing, extract the CNC file, and then post process it into the language of the CNC machine. But clock wheels and pulleys can be defined by relatively few parameters such as the number of teeth, tooth module, number of spokes etc. So I developed my own program to handle this. It is effectively a "fill in the blanks" panel and it generates CNC machine code. The program shown will handle crossing out, mounting hole drilling and tooth cutting. Other programs will route out an escape wheel in the flat, drill plates for pillar and ball race housings, and do a limited amount of engraving.
