Abstract

In micro-milling, the diameter of the micro-milling cutter is smaller than tens of microns, making it difficult to achieve precise positioning with the workpiece, which affects the machining accuracy and the safety of the micro-milling cutter. To solve these problems, the coordinate system has been analyzed. A micro-milling precise automatic tool setting technology has been proposed, which based on the micro-energy pulse discharge sensing principle. A tool setting scheme is proposed to determinate the Central coordinates of workpiece, which is realized by repeating automatically the precise sense from four directions. Experiment is carried out to verify the feasibility and correctness of the technology by analyzing the perceived results.
