Grinding control system

Abstract

Abstract A METHOD FOR DETERMINING AND CONTROLLING THE DISTANCE BETWEEN A VARIABLE SURFACE AND A POINT ON A DEVICE WHICH CONTACTS THE VARIABLE SURFACE, REQUIRING MEASUREMENT OR CONTROL SOLELY OF QUANTITIES RELATING TO THE CONTACTING DEVICE WHERE A REFERENCE POINT A ON THE CONTACTING DEVICE IS CONSTRAINED TO MOVE ALONG A LINE A'' AND A POINT OF CONTACT P FROM THE CONTACTING DEVICE IS CONSTRAINED TO FOLLOW THE VARIABLE SURFACE AND THE ANGLE 0 BETWEEN THE LINE OF CONSTRAINT A'' AND A RADIAL LINE R BETWEEN THE POINTS A AND P HAS A NON-ZERO VALUE. THE METHOD REQUIRES THE MEASUREMENT OF AT LEAST FOUR OF THE FOLLOWING FIVE QUANTITIES: THE LENGTH OF LINE A'' FROM REFERENCE PLANE TO POINT A, THE LENGTH OF THE RADIAL LINE R, THE ANGLE 0, THE FORCE F ACTING UPON THE REFERENCE POINT A DUE TO THE CONTACT OF THE CONTACTING DEVICE WITH THE VARIABLE SURFACE MEASURED ALONG THE LINE OF CONSTRAINT A'', AND THE TORQUE T DUE TO THE CONTACT WITH THE VARIABLE SURFACE WHICH ACTS AROUND THE POINT. ONCE THESE QUANTITIES ARE MEASURED, THE DISTANCE B BETWEEN THE VARIABLE SURFACE AND THE POINT A ALONG THE LINE OF CONSTRAINT A'' MAY BE DETERMINED BY USING THE EQUATIONS B=A''+R COS 0 AND T=FR SIN 0. CONTROL OF THE QUANTITIES SHOWN IN THE ABOVE EQUATIONS CAN OF COURSE, CONTROL THE DISTANCE B. D R A W I N G
