Abstract
A method for programming a multi-segment motion plan for a machine tool which uses program points defined directly on a workpiece surface, and computes a time-optimal trajectory which transitions from air cut to cutting without stopping, while arriving at a cutting start waypoint traveling at a specified cutting feed speed. The programming method also combines what are traditionally separate air cut and cutting commands into a single command, and computes the time-optimal trajectory for all segments. The underlying time-optimal trajectory computation calculates an initial motion profile for each segment based on the waypoint geometry and other constraints, and motion states at the waypoints which join the segments are optimized to provide the shortest total trajectory time. The optimized waypoint states include velocities and accelerations with non-zero values.
