Abstract
The invention concerns a method and a grinding machine (4) for machining a workpiece (1) comprising a desired helical groove. The method comprises a step of grinding a calibration groove (12) on the surface (10) of the workpiece according to a predetermined helix pattern of the desired helical groove and by means of an abrasive wheel (2) of the grinding machine. The calibration groove (12) has a calibration length that is equal or smaller than the predetermined length of the desired helical groove and has a calibration depth (120) that is smaller than the predetermined depth of the desired helical groove. The method comprises steps of: determine an abrasive wheel dimension (22, 23, 24, 25) of the abrasive wheel (2) by measuring the calibration depth; and using the determined wheel dimension (22, 23, 24, 25) for grinding the desired helical groove by means of the abrasive wheel (2).
