Abstract
A method for controlling the process during rough grinding of a workpiece provides that the workpiece is measured during grinding by a sensor to ascertain an actual size, and the measured actual size is corrected in a continuously automatic manner to attain a predetermined specified size according to grinding time. Additionally, a grinding machine for carrying out the method comprises a grinding wheel for rough grinding a workpiece on a grinding spindle head. The grinding machine also has a sensor for detecting a ground workpiece dimension, and a machine controller. The workpiece is held between a workpiece spindle and a tail spindle. The sensor is arranged primarily in a plane defined by a current contact area of the grinding wheel on the workpiece which rotates, and during rough grinding, the sensor continuously transmits measurement signals to the machine controller. The machine controller controls the grinding wheel based on these signals in such a way that the grinding process can be executed as an in-process, i.e., real-time, control.
