PCT No. PCT/SE91/00227 Sec. 371 Date Nov. 23, 1992 Sec. 102(e) Date Nov. 23, 1992 PCT Filed Mar. 25, 1991 PCT Pub. No. WO91/14535 PCT Pub. Date Oct. 3, 1991.A process for machining mils and similar work pieces, especially for grinding the roll surface to a desired shape which process is characterized by continuously meshing the distance between the part of the work piece (1) which is subjected to working and a reference measuring means, preferably a measuring point of the tool or means cooperating therewith, which depends on the position of the working tool (2), with a distance measuring means (4), as well as the temperature of the work piece at or close to the spot of working and/or the distance measuring point with a temperature measuring means (3), submitting signals corresponding to the measured value from the distance and temperature measuring means resp. to a calculating unit (5) which is arranged to calculate the desired size value of the work piece corrected with regard to the temperature measured during the working (actual temperature), and to present (6) at least one of the corrected desired size values (7), the working depth (9) remaining to the corrected desired size value, and the actual size value (8), and/or arranged to automatically control the movement of the tool in relation to the work piece for achieving the desired size of the work piece, corrected to the actual temperature continuously measured during the working. The invention also relates to a device for carrying out this process. |
