    摘要: A numerical control device is disclosed having a parameter memory section 12B that stores discrete optimum parameters for respective operational modes, an operational mode setting switch 20 to allow operational modes to be selectively set through user's operation, and a defect content setting means for registering defect contents of machined results. The optimum parameter, suited for a particular operational mode selected and set with the operational mode setting switch 20, is retrieved for executing setting of the parameter while enabling setting of the parameter based on information obtained with the defect content setting means.

    摘要: A feed velocity of a control axis and acceleration thereof do not exceed a maximum feed velocity and a maximum acceleration defined in mechanical specifications even if a radial operation is carried out for the purpose of a cut-in or escape operation in a contour describing control A radial permissible maximum velocity (Vnp) and a radial permissible maximum acceleration (nullnp) in a contour describing control using a circular interpolation is set separately from a setting value of a maximum feed velocity (Vm) of a control axis and that of a maximum acceleration (nullm) thereof set as mechanical specifications, and when a command of the circular interpolation is given, limitations are given to a radial velocity (Vn) and acceleration (nulln) so that the radial velocity (Vn) and acceleration (nulln) do not exceed the radial permissible maximum velocity (Vnp) and permissible maximum acceleration (nullnp).

    摘要: A portion (14a, 14b) of a chip remover (14) is defined to be vibratory to give an NC machine tool (MT1) a vibration transferable onto a surface (FS) of a work (13) under a finishing by the NC machine tool (MT1), a decision is made whether the NC machine tool (MT1) enters the finishing, and vibration of the vibratory portion (14a, 14b) is controlled, as the decision is true. A chip removal method and an NC machine tool equipped with a spiral chip remover (113) as a chip remover have various chip removal rules for determining permission/prohibition of the operation of the spiral chip remover (113). This spiral chip remover (113) operates based on commands described in a machining program. When a command in the machining program is executed, the permission/prohibition of the operation of the spiral chip remover (113) is controlled according to the chip removal rules.

    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.
