摘要： A numerical controller in which a servo motor is used selectively for position control or speed control. A distribution processing unit (3) forms a position instruction signal based on a part program (1) decoded by a decode processing unit (2). A mode control processing and speed instruction unit (41) or PMC (5) forms a mode signal and a speed instruction signal. A servo control processing unit (71) drives a servo motor (9) based on a mode signal, position instruction signal and speed instruction signal that are input through an axis control processing unit (61).

摘要： A knowledge base unit (IB) stores expert knowledge for finding the causes of troubles, and knowledge for retrieving DI/DO data (IOD) to be exchanged between an NC apparatus (11) and a machine tool (13) and NC internal data (ITD). In case trouble develops and the content of trouble is input from an alarm detect unit (11g), a deduction mechanism (ADPR) automatically reads the DI/DO data and NC internal data (IOD, ITB) using the expert knowledge corresponding to the content of trouble, grasps the phenomenon that is really taking place based on these data, recognizes the cause of trouble from the above phenomenon, and displays the cause of trouble and a method to cope with it.

摘要： A numerical control apparatus for a machining tool having a cross rail (13) movable in the direction of a W-axis and a quill (15) disposed on the cross rail (13) and movable in the direction of a Z-axis which is the same direction as that of the W-axis is provided with a switching device in which, when command strokes for the Z- and W-axes, which are supplied from an NC tape, are checked to find a movement command having a value larger than a limit stroke value set for each axis, that portion of the command stroke which exceeds the limit stroke value is converted to a command stroke for the other axis.

摘要： A numerical controller which controls multiple spindles through a plurality of channels (10, 20, 30). When the machining program of the first channel (10) is stopped in response to a single block signal (6), the machining programs of other channels (20, 30) are placed under the feed-holding condition. This makes it possible to maintain synchronism in executing the whole machining program and to prevent the machining from losing balance and from interfering.

摘要： A numerical controller which controls multiple spindles through multiple channels. The numerical controller includes a channel bus (1) having a plurality of slots; a plurality of channels (10, 20, 30) connected to the channel bus (1) to read, decode and execute numerical control instructions of a group of axes; and axis control modules (3, 4) for controlling a plurality of servomotors. These channels (10, 20, 30) share the processing, commonly utilize the external equipment, and constitute a more flexible numerical control system.

摘要： In the controller of a machining center in accordance with the present invention, a plurality of heads or cutters are connected to control shafts of a plurality of control systems, respectively, and are controlled independently by individual programs. The controller includes instruction means for giving a stand-by instruction or stand-by release instruction to the control systems in synchronism with one another and timing setting means for setting a timing of a stand-by instruction or a stand-by release instruction for which synchronization is established between the systems by the instruction means so that a timing of stand-by or stand-by release set for the program of one particular system determines a timing of stand-by control by the program of another particular system. Accordingly, a stand-by system and a system to be released from a stand-by state can be designated arbitrarily and control of a machine tool can be made efficiently.

摘要： A CNC control system for controlling the axes on the side of the CNC (20) from a PMC (10) coupled to the CNC (20). Instruction values of the axes and group classification data are sent from the PMC (10) to the CNC (20) which then initiates the pulse distribution after the instructions of the same group are all received. Therefore, movements can be started simultaneously on a plurality of arbitrarily combined axes on the side of the CNC (20).
