Abstract: The transferring of electronic signal from rotating work piece or cutter presents a challenge problem. In this paper, a wireless communication method is proposed to transmit signal from rotating bodies. The corresponding device including the signal input & transmission module and the signal receiving and processing module was fabricated. The working principle of the wireless system is introduced, and a series of experiment is set up to calibrate the system accuracy and to measure the cutting temperature of the rotating work piece. The experimental results show that the wireless system has a satisfactory reliability and temperature measurement accuracy.

Abstract: Glass is a kind of difficult-to-machine material due to its hard and brittle properties. Although many special hole machining methods for brittle and hard materials have been developed, the traditional drilling is still widely applied because it is simple and reliable. However, the drilling tool for hard and brittle material is an obstacle, especially for small hole drilling. In this paper, two types of diamond abrasive core-tools which are made by electroplating and sintering process are used to machine small holes in glass plates, their structures are introduced and their machining performances are compared. The experimental result indicates that these diamond abrasive tools are satisfied for small hole machining in glass, and the performance of electroplating tool is better than that of sintering one.
