Provided is a tool path generation method for generating a tool path (Tp), along which a workpiece is machined as a tool (T) moves over a tool movement curved surface (So) generated along a work surface of the workpiece. In this method: a scanning policy is set, which is a rule for establishing a path along which the tool is to move over the tool movement curved surface (So); a dividing line (Cd) is disposed on the tool movement curved surface (So); and the location of an intersection of the dividing line and a trajectory of the tool moving over the tool movement curved surface is calculated on the basis of the scanning policy. A tool path is generated, the path being represented by a movement command for curve interpolation using a curve that passes through the location of the intersection.

This machining program generation device is provided with: a storage unit that stores machining conditions for respective tool regions determined on the basis of the number of effective edges in a multi-blade tool; a contact region calculation unit that calculates a tool region which comes into contact with a workpiece during machining on the basis of the shapes of the workpiece and the edge portion of the tool and of a tool path; and a machining program generation unit that generates a machining program on the basis of the tool path and the machining conditions stored in the storage unit in association with the tool region coming into contact with the workpiece.

Machining program generation device and machining method

The present invention sets a single machining point on a plurality of tool path rows, selects a machining point in a prescribed range with the point to be machined as the center, calculates the tool orientation at the point to be machined by way of averaging the tool orientation of the selected machining point of interest, corrects data pertaining to the tool orientation of the point to be machined by way of the calculated average tool orientation, acquires the shape data of a workpiece to be machined and the shape data of a ball end mill to be used, performs an interference check for the workpiece and the ball end mill on the basis of the corrected tool orientation data, and generates a new tool path on the basis of data pertaining to the corrected tool orientation when no interference between the workpiece and the ball end mill occurs.

Tool path generation method and device

The invention is a workpiece machining surface display method by means of which a machining mark generated when a workpiece machining surface is machined by a rotary tool comprising a cutting edge is displayed on a display device. Said workpiece machining surface display method contains: a first step in which the shape and position of an indentation generated by the cutting edge shaving the workpiece machining surface are predicted; and a second step in which an indentation image representing the shape of the indentation that has been predicted in the first step is displayed in association with the predicted position.
