在金属切削中,切削力有着重要意义,它是设计和使用机床、夹具、刀具的基本依据。切削力的大小可采用理论公式及经验公式两种方法来计算。但由于金属切削过程本身的复杂性,目前还没有成熟的理论计算公式供选用。现有公式算出的切削力与实测相差甚远;经验公 In metal cutting, cutting force is of great significance, it is the basic basis for the design and use of machine tools, fixtures, tools. The size of cutting force can be calculated using theoretical formula and empirical formula two methods. However, due to the complexity of the metal cutting process itself, there is no mature theoretical formula for selection. The cutting force calculated by the existing formula is far from the measured value;
