Abstract

<p>A wireless holder system with acceleration sensors was constructed to measure radial and rotational acceleration on a rotary coordinate system. As a new application, we examined the spindle conditions of two types of machining centers, which were the same model with different specifications of maximum spindle rotation speed, and considered the machining characteristics while performing comparison with servo internal information. In addition, we performed monitoring of a ball end mill finishing process, which was difficult to diagnose with internal servo information. The results demonstrated that the proposed holder system made it feasible to monitor the phenomenon of chatter vibration due to anisotropy of rigidity in machine tools.</p>
