Key Techniques and Advances of Grinding/Milling Spiral Flutes on NC Machines with Multi-axis Linkage

摘要

Introduced systematically the forming principles and mathematical modeling of grinding/ milling spiral flutes with numeric control machines, overviewed the functions of multi-axis linkage and the determination technique of the number of the linkage axes, discussed the conversion technique of NC-STEP-NC code in programming with EXPRESS, presented advances of controlling systems with high performance. Much attention was paid to the explanation of the error modeling and the tool interference in the real machining with the error-compensation techniques. Trends were envisioned on key technique study of the forming principles for the spatial spiral flutes, function of multi-axes, tool interference in the real machining and simulation of the operation processing, as well as automatic generation of NC codes and the connection /compatibility of the codes with the mainline NC systems, in future.
