“…The method used in this paper is to position the tool in close proximity to the surface is to inclined the tool to make contact at least at two different points on the surface at the same time. A tool positioning method based on this attribute is known as a Multipoint Method (MPM) [5][6][7][8][9][10].…”

We implement and test a multi-point machining tool positioning technique that positions the tool using only a variation on gouge checking. The result is a method that is roughly twice as fast as an earlier method that performed a numerical search to find a tool position with multiple points of contact with the design surface. A GPU implementation provides an additional factor of ten speedup. Verification of the method was done via simulation and machining and measuring physical parts. Keywords 5-axis machining • Multi-point machining • Gouge checking 1 Introduction Two types of machines, 3-axis and 5-axis machines, are commonly used in manufacturing industries. 5-axis machining have additional degrees of freedom in rotation and tilting about the z-and x-axes, giving extra flexibility in machine kinematics
