The Application of System Parameters in Eliminating Oscillation and Improving Machining Accuracy of CNC Machine Tool

Abstract:

The measures of eliminating system oscillation by using parameters were put forward in semi-closed loop and closed loop control. The setup procedures of parameters were introduced, which included position loop gain, bi-position feedback, mechanical speed feedback. The setting of the parameters such as acceleration of backlash, compensation for static friction, feed forward and look-ahead feed forward of servo were also proposed, for purpose of improving the position accuracy and interpolation accuracy. The application of the system parameters is significant for improving the machining accuracy and ability of CNC machine tools.
