Abstract: To improve inspection efficiency of machining centre for complex workpiece size, an on-line composite inspecting design method in machine centre was presented, which focused on the structure, working principles and software implementation of the inspection system. Based on the principles of non-contact and contact inspection, a composite inspection equipment with embedding function was designed which could be integrated in tool magazine. Thus the criterion of composite inspection was proposed. To satisfy the inspection accuracy demands for different features of workpieces and reduce the entire process cycle, different inspection modes were selected for different demands in machining process, which significantly improved on-line inspecting efficiency. Through the data fusion and the post-process data analysis, the machining quality analysis report for workpieces was given. To prove the method's validity and feasibility, a step gauge was taken as an object to generate 2D and 3D inspection results according to the operation parameters and the precision features, and the rationality of proposed method was validated. It provided a new method for on-line inspection of machining center.
