![]() ![]() Our work is a continuation of the work of Duvedi et al. Multipoint machining determines the position and orientation of a toroidal end mill for five-axis machining such that the cutting edge of the tool touches the part surface tangentially at two or more points of contact simultaneously for each of the tool positions in the machining passes. Verification of the method was done via simulation and machining and measuring physical parts. 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.Ī GPU implementation provides an additional factor of ten speedup. Bisection Method Pseudocode Free Tool PositionsĪ new approach to find gouge free tool positions for a toroidal cutter for Bezier surfaces in Five axis machining Preprint Full-text available Mar 2021 Mukhmeet Sing Jerry Qu Ravinder Kumar Duvedi Sanjeev Bedi Stephen Mann We implement and test a multi-point machining tool positioning technique that positions the tool using only a variation on gouge checking. ![]() Newtons method to find a point of tangency between the tool and the surface. The MPM method has evolved to the Drop and Tilt method of Duvedi et al.
