SYSTEM AND METHOD FOR FEEDBACK-BASED DRESSING OF A GRINDING WHEEL
A method and a system are provided for automatically dressing a grinding wheel used to grind workpieces. A workpiece is scanned to determine dimensions of the workpiece. A computer-readable dimensions datafile is generated containing the dimensions of the workpiece. A processor electronically compares the dimensions of the workpiece with reference or desired dimensions to obtain comparison results, and generates a computer-readable comparison datafile containing the comparison results. The processor transmits the comparison datafile containing the comparison results to a CNC controller, which utilizes the comparison results to control a shaping tool used to shape or dress the grinding wheel so that the grinding wheel produces workpieces having the reference or desired dimensions.

Method for compensating temperature-induced deviations in a grinding machine and machine being equipped corresondingly
Method for compensating temperature-induced deviations in a grinding machine includes controlling the movements of the dressing tool relative to the grinding tool in order to relatively move the dressing tool towards the grinding tool; checking whether a first-cut detection signalizes a contact of the grinding tool and the dressing tool; repeating the controlling and checking steps until a contact between the grinding tool and the dressing tool is detected, and when the contact is detected, then (i) recording the Current Position, and (ii) carrying out a compensation calculation using the Current Position and a reference position.

GRINDING METHOD OF WORKPIECE
A grinding method includes a first grinding step of executing grinding feed of a rough grinding unit and grinding the workpiece to a predetermined thickness while supplying grinding water with a first grinding water amount that allows suppression of wear of grinding abrasive stones and a second grinding step of, after executing the first grinding step, promoting dressing of the grinding abrasive stones to prepare for processing of the next workpiece through executing grinding feed of the rough grinding unit and grinding the workpiece to the finished thickness while supplying the grinding water with a second grinding water amount that increases wear of the grinding abrasive stones and promotes self-sharpening through reduction relative to the first grinding water amount.
