Beschreibung
Zusammenfassung:	PURPOSE:To easily set the reference of work machining by compensating an error in the machining origin of NC data in the device on the basis of the measured value of a cutting position. CONSTITUTION:Position data XDP from a machining origin after trial grinding is a value read out by a tape reader 1. A position measured value XIN contains an error based upon the position data XDP actually. The measured value data XIN is replaced with position data, and the difference between data XDP and measured position data XIN is calculated by an arithmetic means 4, whose arithmetic result is stored in a correction data memory 5 and used as a following data reference.
