Programming Example For Circumferential Milling - Siemens SINUMERIK 828D Manual

Important functions for 3- to 5-axis machining

3.8.7 Programming example for circumferential milling

A workpiece contour needs to be milled at the circumference. Programming is to be from the top
edge of the workpiece and the insertion depth ISD is to be taken into account. In the example,
compensation is performed to the right of the contour with an ISD of 20.
