ABSTRACT:
A numerical control system has a tool holder which supports tools . . . attached to at least two intersecting sides, preferably three sides of a rectangular shape. The tool holder is movable along plural axes, e.g., X and Y-axis directions. A memory circuit is provided for storing the positional data regarding the tips of the tools and a workpiece diameter when the tool holder is predetermined reference points. When a workpiece is to be machined by a selected tool, the data regarding the selected tool and the workpiece diameter are called from the memory circuit, the distance from the tool tip to the outer periphery of the workpiece is computed, and the tip of the tool is moved to the outer periphery of the workpiece. With this arrangement, tools can be changed quickly.
