Research of On-Machine Laser Measurement Method for Cutting Tools

Article Preview

Abstract:

To successfully achieve high precision machining, process technology and on-machine measurement is essential. On-machine laser measurement will be widely used in industry because it is non-contacting, real-time and high-precision. However, proper method for tool shape monitoring and dimensional control are important to research. In this study, the measurement system consists of a laser light source and a quad photodiode array. And two different edge detection algorithms are introduced to determine the position of the tool edge accurately in order to measure the diameter of cutting tool and errors caused by tool runout. The experimental results verify the validity of measuring tool diameter and runout error.
