The Research of CNC Grinder System with Online Detection

Abstract

Analyses the main methods of on-line detection technology in CNC system, and puts forward a method based on eddy current sensor. Because of the grinder’s special structure that different from the lathe’s, fixed the detection device on the Z axis with the cutter, which was proved available. Designed a new sensor structure and using impedance to analyze the signal and process, the experiments show that it has a high precision relatively. Programmed PC software in VB, through G code compiler, the PC can detect and control the system synchronously in the form of motion control card.
