摘　　要：The authors investigate a disturbance-compensating and energy-saving control method for air turbine spindles equipped with a rotation control system designed for use in ultra-precision milling.The controllability and energy-conserving characteristics of the proposed method using the proposed pneumatic regulating device,called a high-precision quick-response pneumatic pressure regulator,were demonstrated experimentally previously.Herein,the proposed rotation-controlled air turbine spindle is first summarised.Subsequently,the proposed rotation-controlled air turbine spindle is set to a milling machine and applied to the milling of an alloy tool steel,to gain data and validate the effectiveness of the in-process tool wear estimation method that have been recently developed and proposed by the authors.Particularly,to evaluate the possibility of applying the proposed estimation method to three-dimensional milling,milling experiments where the air turbine spindle is set at a 45°incline were conducted and the results indicate a high possibility of the proposed method.
