直到目前为止,都是利用实验所得的关系式来计算在切削金属时作用于切削刀具上的切削力。这些通过实验途径所求得的关系式,可以使我们算出的切削力,对于实际应用中能具有足够的准确性。为了求得各种被加工金属的这种关系式,就得进行许多专门的实验。而这些实验,又因为影响切削力的因素很多的缘故,往往需要进行若干次,方能得到满意的结果。自然,有必须要把切削力,比如使金属切削产生变形的力,与被加工金属材料的强度特性、塑性特性、刀具的几何形状、及金属切削层的尺寸连系起来。当我们得到了表示切削力与被加工金属的物理机械特性之间的关系,并能得出可靠的结果的方程式之后,则用来直接决定切削力的一切繁难而又
Until now, the experimental correlations were used to calculate the cutting forces acting on the cutting tool during the cutting of the metal. These relations obtained through the experimental approach, we can calculate the cutting force, for practical applications can have sufficient accuracy. In order to find this relationship between the various metals to be processed, many specialized experiments are required. And these experiments, but also because of the many factors that affect the cutting force, often need to be carried out several times in order to be able to get satisfactory results. Naturally, it is necessary to link cutting forces, such as the forces that deform metal cutting, with the strength characteristics, plastic properties, the geometry of the tool, and the size of the metal cutting layer being machined. After we have obtained an equation that expresses the relationship between the cutting forces and the physical and mechanical properties of the metal to be machined, and which yields a reliable result, all the forces that are used to directly determine the cutting forces
