Dynamic cutter runout measurement with laser sensor

Abstract

The cutter runout is very common in machine milling and has a great effect on the surface accuracy. In this paper, a measurement of radial cutter runout in revolving milling tool is proposed by using the laser sensor. A laser beam is projected onto the milling tool edge and subsequently reflected. The diffuse reflection is captured by the sensor and the displacement between the cutter and the laser sensor is obtained. Based on the dynamic displacement, the cutter runout is calculated. The experimental results show that the radial cutter runout is dynamically varying in the constant rotation speed and the runout fluctuation largens with the increasing speed. © Springer-Verlag Berlin Heidelberg 2012.
