摘要： A motor controller is configured to judge whether or not the amount of displacement of a driven body after the direction of movement of the driven body is reversed, exceeds a predetermined threshold value, and whether or not the amount of displacement of a motor after the direction of movement of the motor is reversed, exceeds another predetermined threshold value. When the amount of displacement of the driven body exceeds the threshold value, or the amount of displacement of the motor exceeds a second threshold value, the correction of the commands to the motor is terminated.

摘要： A method is employed to eliminate undesired velocity reversal in a motion profile. A start speed, a start acceleration, a speed limit, an acceleration limit, a deceleration limit, an acceleration jerk limit, and a deceleration jerk limit are programmed for the motion profile. A critical jerk value needed to avoid velocity reversal associated with the motion profile is calculated. The critical jerk value is compared to the programmed deceleration jerk limit. The larger of the critical jerk value and the programmed deceleration jerk limit is set as a computed maximum deceleration jerk limit for use with the motion profile. In this manner, the computed maximum deceleration jerk limit will never be lower than the critical jerk and undesired velocity reversal is eliminated.

摘要： The servo control method operates a set value of a first-order lag time constant of a feedback compensation by both a detected mechanical position value and a transfer function corresponding to a change of an angular velocity about each axis under a multiple-axes simultaneous control. Further, the servo control method sets a feedforward amount so that the transfer function about the each axis is the same.

摘要： The feed system (30) for a honing machine (10) provides a capability to dynamically correct in real time errors in bore size inferred arising from variations in feed force, and a method of operation of the same. The system (10) allows a user to select between rate and force controlled honing modes, which provides one or more of the advantages of both modes. The system provides capabilities for automatic rapid automatic bore wall detection, compensation for elasticity of elements of the feed system (30) and honing tool (14), and automatic tool protection. The system is automatically operable using feed force, feed rate and positional information for honing a work piece (20) to one or more target parameters, such as one or more in-process sizes and a final size.

摘要： A numerical control device which controls a feed axis of a machine tool has a storage unit which divides a range of movement of the feed axis into a plurality of regions and stores a plurality of control parameters corresponding to the divided plurality of regions in advance, a position detection unit which detects a position of a feed axis at the time of machining a workpiece, a parameter selection unit which reads out control parameters corresponding to a divided region to which the detected feed axis position at the time of machining a workpiece belongs, and a servo control unit which controls the feed axis using the read control parameters. Due to this, it is possible to provide a numerical control method of a machine tool which realizes stable machining precision without regard as to the feed axis position and a numerical control device which conducts that method.
