|---|---|---|
In practical machining, the multi-axis actual dynamic performances don't match well, which reduces the profile precision greatly. The computer numerical control (CNC) machine tools contour error coupled-control strategy based on line interpolation and curve interpolation is developed in the paper. After analyze the conventional CNC contour error control scheme, put forward the contour error coupled-control scheme based on line interpolation and curve interpolation; Then bring forward the contour error computing models based on line interpolation and curve interpolation; Furthermore, add the obtained contour error to the following error of current sampling period, and send the results to CNC PID position controller to calculate position controlled quantity in order to compensate contour error. The contour error compensation control experimentation results show that the developed approach can reduce contour error effectively and enhance profile precision further. |
