Abstract

The machining method of double-arc spiral internal bevel gear with nutation drive-by milling cutter was proposed in this paper. The mathematical modelling of milling cutter trajectory and axial cut-off of forming milling cutter was established, the special machining tool model of bevel gear was further developed by Solidcam, the simulation machining of bevel gear was carried out. Then, the gear model obtained after simulation was compared and analyzed with the theoretical gear model, and the ideal experimental results, confirmed the CNC modelling milling method processing technology could be used to process bevel gears, the research is very important to improve the development of nutation dynamic transmission.
