Compensating the cutting edge displacement during micro milling - a mechatronic approach

摘要

The turnover of micro system technology (MST)-based products increases within the next years. This leads to the challenge of reliable processes with narrow tolerances. Processes as micro milling still have to deal with scale effects and narrow tolerances usually are only producible with high efforts. This article shows a mechatronic clamping system to compensate several inaccuracies at once. The cutting edge displacement results from inaccuracies in the machine tool, the clamping system and the milling tool. Compensating the cutting edge displacement while rotating with nominal rpm is an effective way to increase the accuracy up to 1μm.
