Improving the grinding efficiency of the external camshaft sprocket

Yuri Petrakov

Abstract


A new technique and application program for automating the programming of the operation of grinding the cams of the outer sprocket of the limited slip differential on a CNC grinding machine is presented. The program is based on the created digital model of the grinding process, which allows modeling and determining the main characteristic of the process - MRR - Material Removal Rate. The resulting simulation file, containing an array of cutting force data with reference to the polar angle of the sprocket contour, with the help of another specially developed application program, is used to design the law governing the spindle speed of the workpiece, which provides a certain stabilization of the cutting process. Modeling of grinding with this control shows that if the original MRR variation range of the process is preserved, it is possible to increase the productivity of the operation by at least 1.5 times.
