Abstract
The present disclosure discloses an ultra-precision machining method, including determining a total material removal amount based on a product to be machined and a blank, and performing rough machining to complete a material removal amount of the rough machining; after the rough machining, establishing an ultra-precision machining error prediction model by using an existing machining error, and predicting a semi-finishing error; re-establishing an ultra-precision machining error prediction model considering influence of the semi-finishing error; and finally performing finishing process planning. In the ultra-precision machining method according to the present disclosure, influence of the finishing error is considered, the ultra-precision machining error prediction model is re-established, and by integrated optimization of process parameters of the semi-finishing and the finishing, machining precision of ultra-precision machining is further improved without reducing machining efficiency.
