Theoretical Analysis and Simulation of the Effect of Frequency on Cutting Force in Precision Vibration Machining

建立了振动切削中切削力的数学模型,进行振动切削中频率对切削力影响机理的研究,并通过数值模拟的方法,首次从理论上给出精密振动切削中频率对切削力的影响规律。同时,还研究了在不同的振动切削条件下,切削力随切削参数变化的变化规律。

A rational model of cutting force in vibration cutting is established, and the vibration cutting mechanism is analyzed. Specially, by the method of numerical simulation, the effect regulation of frequency of vibration on cutting force is theoretically discussed for the first time in precision vibration cutting. And the relationship between cutting parameters and cutting force is probed into on the different cutting conditions.
