LESSON 4.5 · 4:39 · CHAPTER 4 · PROCESS PLANNING

Speed zones, tilt, off-part motion

The last group of planning decisions is about how the machine moves, not where the material goes. Direction (one way or back and forth), the moves between courses, the speeds along a course, how the axes share the work, and the tilt of the head. None of them changes the ply; all of them change the cycle time, and speed and tilt change quality at the course ends and on curved areas.
