Realization of Online Measurement Technology and its Application in the Intelligent Machining Cell

In view of the continuous unmanned machining of revolving workpiece, this paper has integrated the industrial robot with machine vision, mill-turning center and trigger online measurement systems into an intelligent machining cell. It has achieved the automatic loading and unloading material, automatic adjustment of the Machine Coordinate System (MCS) of workblank, automatic compensation of machining errors and workpiece diameter and roundness of the on-machine inspection. In order to ensure the accuracy of continuous unmanned machining of the intelligent machining cell, the main factors that affect the accuracy of online measurement system and the corresponding solutions are analyzed. On this basis, a machining instance is made to verify the validity of the trigger online measurement technique’s application in continuous unmanned machining of the revolving workpiece. The results of this study show that the intelligent machining cell can ensure stable unmanned machining with high precision for several hours.
