In order to avoid repeated positioning during the processing of the toroidal worm and improve the processing efficiency and accuracy,this paper studies the integrated milling and grinding method of dual-cone enveloping toroidal worm.An integrated milling and grinding machine for the dual-cone enveloping toroidal worm is proposed.A forming milling cutter and a double-cone grinding wheel are integrated on a tool holder to realize the rough milling and the finishing grinding of the toroidal worm.The rough milling method of the toroidal worm is proposed,and the change rule of the milling allowance is analyzed to realize the effective control of the machining allowance.For the toroidal worm with a given throat tooth thickness,Vericut software is used to simulate the milling and grinding of the toroidal worm.Analysis results of the calculation example show that the throat tooth thickness of the toroidal worm obtained by the integrated milling and grinding method meets the design requirement.The research can realize the rapid and high-precision machining of the toroidal worm.
