Fabrication of Minitype Cutting Tool Based on the Electrode Dressing Technique

Abstract:

Based on the electrode finishing technique in electrical discharge machining (EDM), a new method is proposed in the article to fabricate minitype cutting tool efficiently. The research on the techniques to attain the minitype cutting tool was based on analyzing the feature of EDM on minitype cutter. The process of fabrication for minitype cutting tool is determined, and the minitype grooving tools with the characteristic sizes of 70 μm were made of two types of materials. This fabrication method proved to be applicable to high efficiency fabrication of minitype cutting tool. The factors affecting precision of minitype cutter were analyzed, the causes for worse shape precision and surface roughness were described specifically, and the suggestions to improve the machining quality were proposed.
