Research on the Impact of CNC Servo Dynamic Characteristic for the On-Line Detection Precision

Abstract:

CNC machine tools are widely used in precision machining and automation production. The on-line detection technology provides an efficient testing method for quality control in CNC machining process. And the CNC servo dynamic characteristic is an important factor affecting the accuracy of on-line detection. In order to study the effects of servo dynamic characteristic, CNC servo system mathematical model was set up, probe system error model was established based on probe measuring time sequence and on-line detection error model was built. The cylindrical feature measurement example shows that on-line detection accuracy is improved through the secondary trigger measurement method and the probe path planning.
