    摘要: A numerical control device adapted to control a plurality of transfer machines mounted on a transfer line. The numerical control device is composed of an NC section (13) for controlling the axes of the transfer machines and a PMC section (14) for executing sequence control. The PMC section (14) reads current position data from a current position register (16) of the NC section (13) through a window, and compares the read data with previously set zone data (19). A function instruction (18a) delivers the result of the comparison as a zone signal, and executes a modification control of an execution sequence by using the zone signal. Therefor, a high-accuracy region signal can be set.

    摘要: A rotation control system for a screw of an injection molding machine is so arranged that an injection shaft 2" and a screw (2) are driven by electric motors (20) and (22). An output signal from an injection shaft position sensor (21), which provides information indicative of rotation of the electric motor (22) driving the injection shaft 2", is applied to an error register (35-1). The position of the injection shaft is sensed by monitoring the error register (35-1), and the rotational speed of the screw (2) corresponding to the position of the injection shaft 2" is obtained by utilizing an override function.

    摘要: A numerical control method for a numerical control system having a numerical control unit (NC) for numerically controlling a machine tool or the like, as well as a programmable controller unit (PC), wherein when machining is suspended and then resumed, the NC unit (1) runs the machining program from the beginning of the machining program up to a prescribed block at which machining is to be resumed, without peforming a distribution operation. During running of the program, data regarding M-, S- and T-functions in the machining program are successively delivered to and stored in the PC unit (2). At this time the PC unit (2) does not send these data to the machine side. Machining is resumed at the conclusion of a search operation up to the prescribed block. However, since the M-, S- and T-functions have already been set automatically in the PC unit (2) to conditions exactly the same as those that prevailed at the suspension of machining, the machining operation can be resumed smoothly from the instant of machining resumption.

    摘要: A tapping machining method for moving a tapping tool to a commanded position in synchronism with rotation of a spindle, to subject a workpiece to threading, and thereafter rotating the spindle in the reverse direction and withdrawing the tapping tool from the workpiece in synchronism with rotation of the spindle. The steps of the tapping machining method include moving and positioning a spindle, namely the tapping tool (4), from an initial point (Pi) to an approach point (Pr) in the depth direction (along the Z axis) while being rotated at a constant velocity. Then a pulse distribution calculation is started by using the pitch of a screw and pulses of a frequency proportional to the rotational velocity of the spindle, and threading is performed while the tapping tool is moved toward a target position (Pe) by the distributed pulses. Next, a spindle reverse rotation command is produced for rotating the spindle in the reverse direction without halting the pulse distribution calculation, even when the tapping tool arrives at the target position (Pe). Thereafter, the tapping tool is moved in the depth direction in synchronism with rotation of the spindle during forward due to inertial rotation. The tapping tool (4) is raised up to the approach point (Pr) by the distributed pulses after the spindle rotates in the reverse direction at a point (Pm), and the pulse distribution operation is ended after the tapping tool arrives at the approach point (Pr).

    摘要: A machining end detecting device detects whether each hole or the like has completely been drilled to its bottom or not, and the latest drilling information is stored in a nonvolatile memory. In the nonvolatile memory are also stored modal data sequence numbers assigned to drilling start position determining blocks and the latest information on a drilling restart position. Upon inputting a drilling restart command from key input means such as a cycle start button, a restart block indexing device indexes, from a numerical control machining program, a restart block necessary for resuming drilling of an unfinished hole or the like on the basis of the sequence numbers and the machining end detection information stored in the nonvolatile memory. A restart positioning device positions a drilling machine at the drilling start position stored in the nonvolatile memory, and a control device causes the drilling machine to restart with the indexed restart block from the specified position.
