High-speed 3-D Measuring System for Wheel working Face on the Machine

Abstract

In grinding, it is required to clarify the processing phenomenon and the process to be made intelligent. The acquisition of detailed tool information is necessary for the purposes. Consequently, not a small number of measurements for wheel working face has been reported. This measurement is expected to be high-speed and performed on the machine. However, there is no measuring system, which is suitable for these purposes. Therefore, this paper describes a high-speed 3-D measuring system for wheel working face on the machine. In this system, a sensing head similar to a laser displacement meter is used. The sensing head is attached to grinding head by two automatic stages. The wheel rotating at 30m/s peripheral speed is scanned by these stages. The scanning resolution is 3μm for X, Y, and Z respectively. This system essentially does not have any limitation for the measurement area. The results of measurements are studied experimentally. As a result, the data obtained by this system is in good agreement with that by a laser microscope.
