Notes:
In conventional machining, cutting conditions such as cutting speed, feed rate, and depth ofthe cut have great influence on the surface roughness. In micro machining, however, the surface shapeis affected by not only the machining parameters mentioned earlier but also tool stiffness, systemstability, and workpiece properties caused by the miniatured structure and cutting tool. Especially, ina micro-machine system, the difference between the cutting forces in the recursive cuts introduces thevibration easily. A high spindle causes instability of the system, increases the temperature in thecutting process, and also changes the tool’s shape. This study introduces a method to predict thesurface shape of the workpiece based on the machining conditions in micro milling. The micro-milledsurfaces in different machining conditions are predicted by a computer simulation including thevibration model and the simulated results show good agreement with the experimental results
