Research on Geometric Error Compensating Technique ofCNC P3G Grinding Machine
Kinematic accuracy is a key reason which influence workpieces geometric error precision on traditional working process of precisely CNC ( Computerized Numerical Control ) P3G ( polygon profile with 3 lobes ) grinding machine. A systematic geometric error model has been presented for CNC P3G grinding machine, proposed multi-body system theory integrate with the structure of CNC P3G grinding machine tools, researched on the machines space geometric errors. By means of separate geometric errors from the machine tools, build geometric mathematical error model. Then, identify 21 error parameters through method of 9 lines, analysis and calculate the total space geometric errors of the workpiece and wheel. Finally, formed a parameter-list and applied software error compensational technique, achieved real-time control to the motions of workpiece and wheel. Experimental results shown that the geometrical error modeling technique is accurate and efficient, and the precision of CNC P3G grinding machine is highly raised 70％.
