摘要
En 中文
In this paper we studied the influence of micromachining parameters on processed surface quality. Usually in discussions about micro-cutting or micromachining, the grinding or diamond turning processes are considered. Cutting tools used in the mentioned processes do not have regular constructive geometry and, in this case, it is difficult to use constructive geometric parameters such as clearance angle alpha or rake angle gamma to optimize the quality of the machined surface. In order to determine the influence of the cutting tool's constructive geometry on the hardness of the machined material, we used a fractional factorial design of a centered and rotatable type 2(6-1). A mathematical model based on five independent cutting parameters was created that allowed optimization of surface quality based on obtained roughness. The results can be applied in micromilling or microturning.
