NC Reconstruction of High Accuracy Spheres Grinding
The design of NC reconstruction of a machine tool and the parameters conversion are elaborated by means of an example of sphere grinding using a common grinding machine which has been reconstructed by special NC technologies. The grinding of a large size sphere is realized by using the linear instruction. The variable speed rotary grinding of a large size sphere is realized by using the arc instruction. The instantaneous compensation of the grinding wheel is realized by using the screw instruction. The function and application scope of NC technology are expanded because of variable speed rotary motion and instantaneous compensation of the grinding wheel.
