Instable process behaviour is one of the biggest challenges in micromilling and has a significant impact on tool wear. This leads to reduced workpiece quality and higher scrap. Therefore, it increases the resource and energy consumption. This paper presents a new simulation method and uses the example of a micro ball end mill for machining X37CrMoV5-1 to show how tool deflection and process forces can be determined as a function of individual process parameters and how optimal process kinematics can be achieved. For this purpose, the individual modelling steps are presented and it is explicitly shown how the necessary characteristic values for the simulation can be determined experimentally.

摘要

Instable process behaviour is one of the biggest challenges in micromilling and has a significant impact on tool wear. This leads to reduced workpiece quality and higher scrap. Therefore, it increases the resource and energy consumption. This paper presents a new simulation method and uses the example of a micro ball end mill for machining X37CrMoV5-1 to show how tool deflection and process forces can be determined as a function of individual process parameters and how optimal process kinematics can be achieved. For this purpose, the individual modelling steps are presented and it is explicitly shown how the necessary characteristic values for the simulation can be determined experimentally.
