Workpiece-attachment-information reporting device

A workpiece-attachment-information reporting device including a control unit comprising:

• a movable range setting unit which sets a movable range of a machine tool, comprising a cutting tool, in a predetermined rotational feed axis direction;
• a posture setting unit which sets a mounting posture of the workpiece mounted on a workpiece mounting surface of the machine tool;
• a path setting unit which sets a tool path based on the mounting posture of the workpiece set at the posture setting unit;
• a range calculating unit which calculates an operating range of the machine tool in the predetermined rotational feed axis direction when assuming that the cutting tool moves relative to the workpiece along the tool path set at the path setting unit;
• a target posture computing unit which finds a plurality of target mounting postures of the workpiece by which the operating range calculated by the range calculating unit becomes within the movable range set at the movable range setting unit;
• and
• a reporting part which reports to and displays on a display unit a range of mounting postures of the workpiece which eliminates stroke-over of the predetermined rotational feed axis based on the plurality of target mounting postures found by the target posture computing unit,
• wherein the posture setting unit sets a plurality of mounting postures of the workpiece,
• the path setting unit sets tool paths corresponding to the plurality of mounting postures set at the posture setting unit,
• the range calculating unit calculates operating ranges in the predetermined rotational feed axis direction corresponding to the tool paths set at the path setting unit, and
• the target posture computing unit judges whether the operating ranges calculated at the range calculating unit are in the movable range set at the movable range setting unit so as to find the target mounting posture, and
• wherein the machine tool comprises a plurality of rotational feed axes, and the reporting part displays the target mounting posture to eliminate stroke-over of the rotational feed axes in an angular range in a plurality of directions.
