| Abstract: | A method based on programmable logic controller(PLC) to control the teeth-separated precision of numerical control(NC) rack-ground machine was reported.PLC acted as the core of the method.Basing on the existing rotary encoder of servomotor and ballscrew,a grating scale was added to form a closed loop control.And the high-speed counting module and interrupt of PLC was applied to process the position feedback.The control structure diagram was presented.The grating scale measuring system and the control implem... |
