Abstract
In the CNC machining on complex parts, how to compute contour error with high precision and distribute contour error correction quantity on each sampling period, is much significant to improve matching degree among each axis. Consequently, a CNC contour error compensation control approach with stable calculation error, high computing precision and satisfied real-time characteristic, is researched in detail in the paper. Firstly, compute the contour error according to the actual cutter position dots and the straightway approximate nodes; Secondly, add the obtained contour error to the following error of current sampling period, and send the results to CNC position controller to calculate position controlled quantity; Finally, the contour error compensation contrast experimentations are done on the three-axis linked CNC test table, and the experimental results show that the developed approach can reduce contour error effectively.
