Kurzfassung

Machining three-dimensional structures by micromilling places high demands on the design of the process. A simulation of the process allows identifying critical process condi-tions in advance and to adjust the process parameters accordingly. To simulate the cutting forces, a geometric simulation is used. The simulation is able to calculate the exact volume of actually machined material at any point of time during the process by using a geometric model. The determined shapes of the machined material are very accurate and are used to calculate the resulting cutting forces by means of an adapted cutting force model. The presented paper focuses on the measurement and simulation of the cutting forces. The influence of downscaling the tool diameter to the cutting forces is analysed and simulated.
