Abstract
A grinding machine is provided with a workhead support means having pivotable shaft means on which the support means is pivoted by a servomotor/pinion arrangement controlled by a programmable controller and a position indicating means on the pivotable shaft means that inputs angular shaft position signals to the controller. Adaptive control components may also be included in the control arrangement. The workhead support means is thereby pivotable to vary the angular relationship of the workpart axis to the grinding wheel axis to effect a desired taper or contour grind or to compensate for changes in grinding parameters causing out of tolerance ground workparts. Special releasable clamps are provided to fix a desired position of the workhead support means and yet release same for pivoting movement. Fluid lift mechanisms are also provided to reduce friction between the workhead support means and the adjacent machine base member during pivoting.
