Question 1

How does programming with automatic tool radius compensation differ from tool center programming?

Accepted Answer

Programming with automatic tool radius compensation differs from tool center programming in two ways. First, the programmed coordinates of the toolpath are the actual corners or edges on the workpiece. The tool is assumed to be tangent at any of these points where one geographical element meets another. Tangent means that just one point of the circle (cutter) touches the line or arc from the workpiece. Automatic tool radius compensation differs in a second manner: we have to transition from tool center coordinate to tool edge (or tangent) coordinates. This will be referred to as lead-in and lead-out.

Accepted Answer

A)  X-Y plane
