This helical motion combines circular movement in one plane with a simultaneous linear motion in a plane perpendicular to the first. For example, the path from point A to point B (Fig,A) on the envelope of the cylinder combines a circular movement in the x-y plane with a linear displacement in the z direction On most CNC systems this function can be executed in two different ways: - GO2: Helical interpolation in a clockwise direction - GO3: Helical interpolation in .L The thread milling operation (Fig. B) consists of circular rotation of fhe tool around its own axis togerther with an orbiting motion along the bore or workpiece circumference. During one such orbit, the tool will shift vertically one pitch length. These movements combined with the insert geometry create the required thread form. There are three acceptable ways of approaching the workpiece with the tool to initiate production of the thread: 1. Tangential Arc Approach 2. Radial Approach 3. Tangential Line Approach Threading 4Q
