Abstract
A grinding device is operated by grinding of a surface of the workpiece with at least one grinding medium while recording actual data of the surface after grinding with at least one data collection device. Actual data recorded during grinding is then compared with target data stored in an electronic memory in an electronic data processing device. Based on the comparison, adjustments are made to at least one grinding parameter if a deviation of the actual data from the target data exceeds a predetermined limit.
Claims10
A method for operating a grinding device, comprising:
- grinding of a surface of a workpiece with at least one grinding medium,
- recording actual data of the surface of the workpiece after grinding with at least one data collection device,
- comparing the actual data with target data stored in an electronic memory in an electronic data processing device,
- adjusting at least one grinding parameter if a deviation of the actual data from the target data exceeds a predetermined limit,
- collecting the actual data at different points in time,
- using the actual data collected at the different points in time to identify a change in a grinding result,
- determining a condition of the at least one grinding medium based on the actual data collected at the different points in time,
- determining an exchange time at which the at least one grinding medium is changed, and
- emitting one or more of an optical signal and an acoustic signal when the exchange time is reached,
- wherein the at least one data collection device has at least one optical system that comprises one or more of at least one camera, and at least one light source, wherein the optical system is configured to collect the actual data on at least one part of the surface of the workpiece, and
- wherein the optical system collects the actual data on an entirety of the surface of the workpiece.
