基于轴向位置的振动钻削切削力计算

Calculating Cutting Force of Vibration Drilling Based on Axial Location

轴向振动钻削提高了难加工材料的加工性能,但是至今还没有一套成熟的理论体系,能系统说明振动过程机理,对切削力的公式也没有形成一致的观点和方法。本文通过对轴向振动钻削工艺参数分析的基础上,对实际钻削加工区段分两部分进行计算,并利用轴向位置方法,建立了一套可以针对不同材料加工要求的瞬时切削力与各参数的关系模型。

Axial vibration drilling improves difficult cutting materials processing performance, but until now, a set of mature theoretical system isn＇ t formed, that can explain vibration system process mechanism, and the formula of cutting force also not reach a consensus on the consistent viewpoint and method. This article on the basis of analysing the axial vibration drilling technological parameters, dividing the actual drilling processing section into two parts, established a set of relationship model between instantaneous cutting force and the parameters of the model for different materials processing re- quirements, with the calculation method of axial position.
