Beschreibung
Zusammenfassung:	The end-face processing step of this method comprises a position control step for controlling, by means of a control device 5, the position of a processing tool 2. The position control step includes: a preparation step S1 for placing the processing tool 2 at a reference position RP before the processing tool 2 is brought into contact with an end surface ES prior to the initiation of processing; a measurement step S2 for measuring the amount of displacement D of the processing tool 2 in an approaching direction CDa, or in a separation direction CDb, as the processing tool 2 is brought into contact with the end surface ES when initiating the processing; and a correction step S4 for setting, on the basis of the displacement amount D, the reference position RP of the processing tool 2 for the next round of processing.
