摘要： A numerical controller has a tool retraction function for retracting a tool so as not to damage the machined surface of a workpiece when machining of the workpiece by a machine tool is interrupted. The numerical controller identifies a machining method for the machining to be interrupted when a command to interrupt the machining is detected, determines the direction of the retraction of the tool, based on the identified machining method and the feed direction and the rotation direction of a spindle in the machining to be interrupted, and generates a movement path of the tool in the determined retraction direction.

摘要： A numerical controller suppresses change of a axis speed to be slow even when a lookahead distance varies with small steps. The numerical controller includes: a lookahead unit that looks ahead a plurality of instruction blocks from an NC program; an analysis unit that analyzes the looked ahead instruction blocks and creates motion instruction data; a target speed calculation unit that calculates a target speed of the axis based on a lookahead distance; an interpolation unit that generates interpolation data based on the motion instruction data and the target speed; and a servo control unit that controls a motor based on the interpolation data. The target speed calculation unit refrains from recalculation of the target speed when a change of the lookahead distance is within a margin.

摘要： A numerical controller reads out an instruction block included in a machining program, obtains machining information indicating a feature of a tool path instructed by the read instruction block, and stores a machining conditions related to a movement of a tool in association with the obtained machining information. Further, the machining information obtained together with the instruction block is determined, and a machining condition in the movement of the tool instructed by the instruction block is changed based on the determined machining information and the stored machining condition.

摘要： A numerical control device of the present invention includes a control unit that controls a machining tool including a main axis having a screw-hole inspection gauge attached thereto in such a way that a feed-axis motor and a main-axis motor for the main axis perform operations for screw-hole inspection based on a machining program and a determining unit that determines acceptance/defect of inspection of a screw hole machined on a workpiece based on a condition of the feed-axis motor or the main-axis motor during control by the control unit.

摘要： A numerical controller includes a reading analysis unit that reads a CNC program and additional information, a path generation unit that determines a movement path of a tool, and a velocity control unit that determines a velocity for moving the tool according to the movement path of the tool, and machining errors, deterioration of a machined surface quality, or an increase in a cycle time are reduced without increasing a CNC program size and a calculation time associated with control more than necessary.
