CNC in the (Model Engineers') Workshop Same circle, different place

摘要

This series of articles starts with the fundamentals and covers many aspects of CNC programming and machining. The series is not specific to one make or model of machine tool, but it does feature Mach3 and Vectric software throughout. Now that we know how to make the Controlled Point (CP) move in a circular path, we can machine circles, cut circular pockets and peripheries. All very useful. But some jobs use the same circular path more than once, and it would be handy to be able to use the same path in a different position.
