Abstract: In order to improve the accuracy of ball lead-screw
grinding, a new method of compensating input feedforward control is used
in the system of laser feedback error compensation for lead-screw
grinder. Theoretical analyses shows that this input-revising algorithm
can improve the accuracy and the transient response of the system. When
this method is used in the ball leadscrew grinding error compensation
system, the maximum error is effectively decreased.
Key words: Input revising Ball leadscrew grinding Laser feedback
