A fluting method for forming a flute in a workpiece while the workpiece is moved relative to a rotating tool by the combination of a rotating feed shaft with other feed shafts, the method comprising a machining process of relatively moving the rotating tool on a tool path that runs along the direction in which the flute extends and machining the workpiece using a rotating tool with a diameter that is smaller than the width of the flute. The machining process changes the relative position of the rotating tool with respect to the workpiece and performs machining multiple times so that the rotating tool makes internal contact with a circle that has the width of the flute being formed in the workpiece as the diameter.

Groove-forming method, control device for machine tool and tool path generating device

A tool path-generating method for computing a tool path to process a workpiece, wherein the tool path for a designated tool when processing using the designated tool is previously established. The tool path-generating method includes a path-computing process for computing, on the basis of the tool path for the designated tool, the tool path of a substitute tool differing from the designated tool when processing with the substitute tool. The path-computing process computes the portion that ultimately forms the machined surface when the workpiece is processed using the designated tool and sets the tool path for the substitute tool on the basis of the portion that ultimately forms the machined surface.

Tool path-generating method, machine tool control device and tool path-generating device

A machine tool control device includes a calculation unit for estimating, on the basis of the tool path for machining using a tool and information on the workpiece, the portion of the tool that forms the final machined surface. The control device also includes a feed rate-setting unit for estimating the fastest moving point, among multiple moving points contained in the portion that forms the final machined surface, for which the relative velocity of the tool with respect to the workpiece is maximum and setting the feed rates for the machine tool movement shafts so that the relative velocity of the fastest moving point is at or below a previously specified relative velocity.
