摘　　要：针对目前无心车床钛合金切削力计算公式推导的困难性和复杂性,通过测量主电机电流的实验方法来探索难加工材料钛合金的切削规律,打破了传统的测量切削力的实验平台,解决了传统方法中实验平台搭建过程的难题。同时以空心主轴电机电流为主要实验数据,结合切削深度以及进给速度等实验数据,在SPSS软件中进行线性回归分析,拟合出了切削力经验公式,验证了该经验公式在实际的加工中的指导意义,为进一步研究钛合金的切削机理奠定了研究基础。A iming at titanium alloy cutting force calculation formula of centerless lathe is difficulty and complexity at present, the cutting law of difficult-machining titanium alloy is explored by measuring the main motor current. It has broken the traditional experiment platform of measuring cutting force and it no need to build a test platform. At the same time, according to the data of centerless lathe＇s main spindle motor current, cutting depth and feed speed, an experience formula of cutting force is fitted out in SPSS by making the linear regression analysis. This empirical formula was verified has actually guided significance in the process and set the stage research for the further study of cutting mechanism of titanium alloy.
