由Kennametal公司的研究报告可知,如果在机床上配备联机刀具磨损测量系统,机加成本可降低40％。为此,联机的刀具磨损测定装置的开发受到了广泛的重视。测定装置的核心是传感系统,现在各种传感系统已相继出现。 1.间接磨损测定法在通过测试切削阻力检测刀具磨损方面,Sandvik公司开发了测试进给方向阻力的 The study by Kennametal shows that machine cost can be reduced by 40% if an on-line tool wear measurement system is installed on the machine. For this reason, the development of on-line tool wear measuring apparatus has received extensive attention. The heart of the measuring device is the sensing system, and various sensing systems are now available. 1. Indirect wear test In testing tool wear through the test cutting resistance, Sandvik has developed a test of the direction of feed resistance
