Abstract: A display apparatus which displays only a portion of an NC command program stored at a specific address. An NC command program stored in an NC command program memory (MEM) is transferred to a specific address portion selection means (SEL). When a selection command is input from a selective-display command input means (IN1), the specific address portion selection means (SEL) selects the portion of the NC command program corresponding to a specific address input thereto from a specific address input means (IN2). The selected NC command program portion is transferred to a display (DRY) where it is displayed.

Abstract: A method of numerically controlling a machine tool which has two or more tools (TL1, TL2, TL3), such as a multiple-spindle automatic lathe, comprises the steps of preparing numerical control dataspecifying a time and a positional relationship between movable spindles (X1, X2, X3, Z), numerically controlling the position of each of the movable spindles (X1, X2, X3, Z) on the basis of the numerical control data; monitoring to determine whether or not a period of time elapsed matches the time specified by the numerical control data; and, when the time elapsed is equal to a period of time specified by the numerical control data for a specific movable spindle, controlling the position of the movable spindle by means of subsequent numerical control data therefor.

Abstract: A controller, such as a numerical controller, displays the changewith time of input/output statuses or an internal status by a timing chart, to facilitate analysis of the cause of interference concerning signal timing. The controller has a status display unit (22) which includes: a keyboard (25) for inputting desired display data, display data input times, and display data input-inhibit conditions; a timer (26) which generates a clock signal at predetermined timing; a memory (27) which inputs desired display data during an interval of a desired input time in accordance with the conditions set through the keyboard; a display (28) which displays the data input to the memory when the input-inhibit conditions are satisfied; and a processor (29) which controls the memory and the display in synchronism with the clock signal.

Abstract: A method for determining the acceleration/deceleration time constant of a servo motor in planning the path of an industrial robot. When the time constant is determined, calculation is made taking into account the torque generated by the interference with another shaft caused when a plurality of shafts are simultaneously operated when the robot is moved along a desired path. Therefore, the path of the robot is not deviated since the torque is not saturated even when there is an influence of the interferential torque. In addition, when the influence of the interferential torque is little, a shorter time constant is given, and hence the cycle time is improved.

Abstract: A servo control circuit, which is employed to drive a servo motor at a commanded speed and torque, is provided with a servo motor voltage supply circuit, a servo motor drive current detection circuit, a servo motor revolution detector, a counter which counts revolution detection pulses therefrom, a processor which controls a current loop in accordance with an external torque command input, and also controls the output voltage of the voltage supply circuit, and a main processor which outputs the torque command. It is possible to omit the counter which is conventionally employed for inputting positional data, since the number of pulses generated during a period T1 for the current loop control is counted and utilized as positional data during a period T2 for the main processor. Therefore, the servo control circuit is advantageous from the viewpoints of both construction and economy, and is applicable to the control of various kinds of DC or AC servo motor.

Abstract: A wire cut electric spark machine provided with a tapering control unit improved so that a tapering process can be carried out with a high accuracy even when the rigidity of a wire electrode varies due to the variations in the temperature thereof which occur when a working current varies. The information representing the relation between a working current and a tapering angle in the whole control range of a taper angle to be controlled is prepared in advance. A means for setting a working current, and a means for inputting a current program so that the working current varies with the lapse of time, or a means for detecting the working current are provided. The above information is read in response to the working current set, and program-inputted so that the current varies with the lapse of time, or detected. Computation is carried out on the basis of this information, if necessary, to determine a correction value with respect to the tapering angle. The tapering angle is corrected by using this correction value, and a tapering process is then carried out by using the corrected tapering angle.
