Research on Tool Wear Form in Micro Turn-milling Process

摘要

In micro machining,turn-milling tool wear is a key factor for part surface quality.This paper carries on experiments on end mills wear in micro turn-milling machining,aiming to research the wear form and provide some reference data for developing wear standard of small diameter end mills.To measure wear condition of end mills,machine vision technique is utilized.This paper designs and sets up an online end mill wear measurement system for a micro turn-milling process center.With a series of experiments on small diameter end mills,wear conditions of different cutting positions are researched.Based on analysis of experiment data,wear characteristics and wear rule for micro turn-milling process are summarized in this paper.
