SETTING DEVICE FOR COORDINATE SYSTEM OF MACHINE TOOL

摘要

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, but contains an error actually. The difference between measured value data XIN and position data XDP is calculated by an arithmetic means 4, whose arithmetic result is stored in a data memory 7; and a correction value is read out of a correction data memory for each tool and a deviation in tool fitting is corrected in the device to facilitate work machining.
