Tool path generation method

A tool path generation method includes inputting a first function derived from a polynomial expression including a plurality of coefficients representing a first curved surface, generating a first tool path based on the first function, inputting the first tool path to an NC device of a machine tool and machining a workpiece by relative movement between a tool and a workpiece along the first tool path, measuring the shape of the workpiece at a plurality of measurement points on a surface of the machined workpiece, calculating, for each of the measurement points, a symmetrical position with respect to the first curved surface in a direction perpendicular to the first curved surface as a correction point, obtaining a second function representing a second curved surface based on a series of position data of the correction points, and generating a second tool path based on the second function.

Tool path generating method

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

This tool path generating method, which generates a tool path for machining a corner section at which a recess section machined in a workpiece intersects with the outer circumferential surface of the workpiece, includes: a step for calculating a virtual traveling direction, which is a movement direction of a point on the rotational axis line of a rotating tool when the recess section is machined; a step for calculating the position of the corner section from the virtual traveling direction and shape data of the workpiece; and a step for generating a tool path for machining along the calculated position of the corner section.

Tool path generating method and tool path generating apparatus

A cutting method in which a workpiece is cut on the basis of a plurality of tool paths parallel to one another into a shape having a corner that protrudes outward. A machining step for machining the workpiece on the basis of one tool path and a moving step for moving to the starting point of the next machining step after the completion of the one machining step are repeated. In the machining step, a cutting step for cutting the workpiece in the one tool path and a removing step for removing a burr by moving a tool relatively to the workpiece in the same tool path as that of the cutting step in a region forming the corner are successively performed.

Cutting method and tool path generating device

In this machining method, in which a rotary tool is moved relative to a workpiece and/or the workpiece is moved relative to the rotary tool so as to machine a curved surface on said workpiece, rotation in the direction of said curved surface is added to the workpiece such that the positions of reversal marks left on the curved surface per tool path are dispersed in the direction of said rotation.

Machining method and a control device for a machine tool

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.
