Abstract: A method for evaluating a toolpath traveled by a rotating tool when the rotating tool machines a workpiece while moving relative to the workpiece, including: a calculation step for, based on a predetermined target toolpath and the shape of the workpiece before the workpiece is machined by moving the rotating tool along the target toolpath, calculating the dimensions of a contact area of the bottom surface portion of the rotating tool where the bottom portion is predicted to be in contact with the workpiece when the workpiece is actually machined by moving the rotating tool along the target toolpath, said bottom surface portion intersecting the rotational axis line of the tool; and a determination step for determining that the target toolpath is inappropriate if the dimensions of the contact area exceed predetermined threshold values when the rotating tool is positioned at any location along the target toolpath.

Abstract: A tool path generating device for generating a machining program is provided with a determining unit which determines whether or not the effective cutting length of a tool would be insufficient if machining were performed using a first tool path, and an estimating unit which estimates a section of insufficiency, being the section in which the effective cutting length of the tool is insufficient. The tool path generating device is provided with a post-move travel path generating unit which generates a post-move tool path in which the path corresponding to the section of insufficiency has been moved relative to the first tool path to a path whereby the section of insufficiency can be machined using the section of the tool within the effective cutting length, and an auxiliary path generating unit which generates an auxiliary tool path for machining the uncut section remaining in the workpiece.

Abstract: A processing program generation method for generating a processing program (PR) for a work machine on the basis of use-results information for a tool (4) attached to a work machine (2), wherein the use-results information for each part of the tool (4) is obtained, a target use part of the tool (4) is set on the basis of the obtained use-results information, and the processing program (PR) is generated in a manner such that a workpiece (W) is processed using the set target use part of the tool (4).

Abstract: A workpiece-attachment-information reporting device includes a range-setting unit for setting a movable range in a prescribed feed-shaft direction of a work machine, a position-orientation-setting unit for setting the attachment position or orientation of a workpiece, a route-setting unit for setting a tool route on the basis of the attachment position or orientation of a workpiece, a range calculation unit for calculating the operational range in the prescribed feed-shaft direction of a work machine when the tool has moved relative to the workpiece along the tool route, a target-position-orientation calculation unit for obtaining the target attachment position or orientation of the workpiece with the calculated operational range being within the movable range, and a reporting unit for reporting the target attachment position or orientation.
