Prior to Kinetic Control, continuous 5-axis machining operations had to be programmed relative to the center of rotation of the machine. Let’s say one of the machining operations begin at A45 B0 and the lead in move is positioned at X2, Y1.5, Z2 when A is 0 and B is 0. To be at the same point on your part when at A45, the physical X, Y and Z axes would need to at X2, Y.3536, Z1.7678. The posted code would generally look something like:
