Abstract
A method that eliminates or reduces chatter when plunge cutting with boring cutters at different diameters, different tool geometries, different chip loads and different cutting depths, by computing optimal cutting insert locations and relocating such inserts to such optimal cutting locations with different phase angles therebetween; this minimizes the resultant radial force of the combined cutters. The method comprises (a) circumferentially stationing the cutters on the tool at different diameters and depths, but at first phase angle locations; (b) measuring or predicting the maximum radial and tangential cutting forces and chip loads imposed upon each cutter for each revolution of the tool, and repeating such calculation for all revolutions of the tool to acquire force information; (c) computing the different resultant radial forces that result from different phase angle positions for the inserts based on the force information; and (d) selecting the best combination of phase angles that produces a minimal/maximal resultant radial force and relocating the cutters according to such newly selected phase angles for completing plunge cutting.
