摘要：

This paper describes the development of a miniature abrasion-detecting device for a small precision lathe. The device works by detecting the amplitude of the first natural frequency of the cutting tool, which increases with abrasion. By employing a small unimorph piezoelectric vibrator as a sensor and using an electric power control with an analog switch, a miniature, low power device for detecting abrasion is developed. The 30 mm by 30 mm device does not need a regulator in the electrical circuit and runs continuously for more than a week on a coin-sized battery. (C) 2003 Elsevier B.V. All rights reserved.
