摘要

A tool is rotated by a spindle mounted on a Z-axis table carried on a column and moved in the direction of a Z-axis to process a workpiece, while moving an X-axis table supported on a column rising from a bed in the direction of an X-axis and moving a Y-axis table supported on the X-axis table in the direction of a Y-axis to move the workpiece supported on the Y-axis. By controlling the movement of the X-axis and Y-axis tables in a contouring manner to move the workpiece along any path, holes having various sizes and shapes can be made by one type of the tool. Moreover, the wear of a cutting blade of the tool can be compensated by correcting the path of movement of the workpiece.
