Abstract

In order to realize the functions of tool, workpiece replacement, surface roughness, machining defect and tool wear detection in the process of intelligent manufacturing, a system which can realize in-machine detection is proposed by combining robot with machine vision detection technology. The overall structure of the system is composed of CNC machine tools, cutting tools, tool shank, camera, lens, computer and so on. The manipulator is calibrated by the method of simultaneous calibration of hand and eye, the clamping device and camera are installed on the manipulator, and the replacement of cutting tool and workpiece can be realized by using industrial image processing algorithm, as well as the in-machine detection of surface roughness, machining defects and tool wear. The experimental results show that the method can meet the requirements of some tests.
