Relieving of thread milling cutter teeth using a grinding wheel with a common axis

A mathematical description of the method of radial relieving of thread milling cutter teeth with a grinding wheel rotated by two installation angles relative to the axes of the workpiece coordinate system is proposed. This approach simplifies the production of thread milling cutters, since the selection of combinations of installation angles allows one standard wheel to perform profiling of several sizes of thread milling cutters. The developed mathematical dependencies are confirmed by experimental studies, the results of which can be used in the design of comb thread milling cutters for the manufacture of metric threads.
