Abstract


Rotary ultrasonic machining is a tool in the power of ultrasonic vibration attached rotation movement at the same time. This article main research using sessile grinding the rotating power of the ultrasonic machining material removal mechanism, this paper expounds the rotary ultrasonic machining material removal mode, power ductile removal mode are put forward. And use the crystal dislocation theory, explains the mechanism of debris. In-depth analysis of the longitudinal power ultrasonic vibration honing speed of movement of the synthesis, is deduced based on the theory of fixed point synthesis formula of longitudinal ultrasonic wave vibration synthesis speed and established a more suitable for processing the actual critical speed. For sharp shape and material removal mechanism of the spherical particle has carried on the thorough discussion, established the mathematical model when the ultrasonic vibration honing the removal rate of materials. On this basis, the use of ultrasonic honing device of CrMoCu alloy cast iron ф 47 mm motorcycle cylinder process experiments, the abrasive granularity, reciprocating machine peripheral speed, speed, the ultrasonic frequency, amplitude and honing oilstone parameters such as pressure of work was analyzed, and the rotating power ultrasonic honing process parameters is obtained, the rotating power ultrasonic honing processing has a certain guiding significance for practical application.
