摘要：

Micro-milling with cemented carbide micro end mills is characterized by high frequency tool loads and infeeds smaller than 100 mu m. In this paper, measurements of technological characteristics during the micromilling process are presented. The results are used to carry out a load analysis of current micro end mills. Interpreting this analysis, an innovative tool design of micro end mills is developed using the parameter technology in a FEM strain simulation. The new tool design presented here has been successfully verified by micro-milling the tool steel PM X190CrVMo 20 with a hardness of up to 62 H RC.
