Patent number: 10088832Abstract: 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.Type: GrantFiled: September 13, 2013Date of Patent: October 2, 2018Assignee: MAKINO MILLING MACHINE CO., LTD.Inventors: Yuki Tanigawa, Yuji Otomo, Soichiro Asami

Patent number: 10088824Abstract: 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.Type: GrantFiled: September 13, 2013Date of Patent: October 2, 2018Assignee: MAKINO MILLING MACHINE CO., LTD.Inventors: Yuji Otomo, Yuki Tanigawa, Soichiro Asami
