【Abstract】 Facing hyperboloid parts machining difficulties,the paper put forward a new high-speed hyperboloid parts lapping method that uses the bending formation method and expounded the principle of high-speed lapping with the bending formation method.The mathematical model of bending formation lapping tools was established through mechanics and higher mathematics,and the width function expression of the lapping tools was deduced.The analysis of calculation instances indicates that lapping tools can be designed as required through using the method,whose feasibility has been confirmed by the bending experiment of lapping tools.The maximum error of a surface shape is 1.0038 μm,and its precision can satisfy the machining precision requirements of the majority of parts,providing a theoretical basis for further experiments on lapping.更多还原
