摘要： A graphic display apparatus for drawing the path of a tool (tool locus) determined according to commands given by a numerical control (NC) machining program is improved to make it possible to easily identify the NC machining program content by which the path of each part is determined. For this purpose, a movement command block is previously stored which corresponds to the starting point of each tool locus prepared by decoding the movement command block, and a cursor is moved along each tool locus by the input of a cursor moving command. When the cursor has passed the starting point of the tool locus, the movement command block corresponding to the starting point is displayed on a display screen.

摘要： An output system for determining an axial speed for a CNC apparatus which controls the speed depending upon a residual error between the position instruction and the detected position data in order to control positions of the axes. This system comprises means for determining the present speeds of axes from the residual errors, means for determining the present actual speed by combining the present speeds of the axes, and means for producing an output that represents a ratio of the present actual speed to a predetermined maximum speed. An error register stores a residual error (residual quantity) between the position data detected by the position detector and position instructions for the axes from the MPU in the CNC apparatus. A speed instruction is generated from the error register to control the speed. In this case, there exists a predetermined relationship between the residual error and the present speeds of the axes, and this is utilized to derive the present speeds of the axes from the residual errors. When the present speeds of the axes is obtained, the actual speed of the work table can be determined by combining the speeds of the axes. The actual speed thus obtained is converted into an output that represents its ratio to the system's maximum speed which has been set according to a parameter.

摘要： A power supply apparatus for supplying backup power (12) to pulse encoder (24, 34) for detecting the rotation speed of a servomotor. In normal operation a negligible voltage drop occurs, while in the event of a short circuit the current is decreased. Instead of the conventional fuse, a heat-sensitive, protective resistor (R) is provided between the pulse encoders (24, 34) as an external unit and the backup power (12) so as to save labor of exchanging the fuse.

摘要： A system for processing MST functional instruction in a numerical control system which consists of a numerical controller (CNC, 10) and a PMC (programmable machine controller, 20). The numerical controller (10) produces strobe signals MF, SF and TF in the logic state opposite to that of completion signals MFIN, SFIN and TFIN. The PMC (20) judges that an instruction is produced when the strobe signal logic becomes opposite to the completion signal that is being produced. When the execution of MST function is finished, the completion signal is rendered in the same logic state as that of the strobe signals MF, SF and TF. When the completion signal becomes the same logic as the strobe signal, the numerical controller (10) determines that the processing of MST function is finished. Therefore, it is determined that the instruction is issued when the completion signals and the strobe signals are different from the respective output signals. Further, when the strobe signals and the completion signals are in the same logic state, it is determined that the processing is finished. Therefore, no cycle is required for confirming the signals, and the processing time is shortened.

摘要： A method and apparatus for dealing with an instantaneous voltage drop of the power supply in a CNC equipment, by which any input unit for switching on/off the external power supply can be dispensed with and the button operation is simple. In a CNC equipment (3), provided are a power supply circuit (31) which is connected to an external power supply (1) and forms a DC power supply used in the CNC equipment (3), a voltage monitoring circuit (33) which issues to a CPU in the CNC equipment an interruption instruction for stopping a servo system when it senses the voltage drop of the output of the power supply circuit (31), and a means (32) for generating a reset signal, which outputs a reset signal to the CPU when it receives from the voltage monitoring means (33) the signal representing that the power supply has been restored from the instantaneous voltage drop. Upon the restoration from the voltage drop, the means (32) keeps the CPU (34) in a reset state for a certain time and then releases the reset stage of the CPU (34) to run the system program. Thereafter, by pressing the start button of the CPU (34), a programmed operation can run.

摘要： This invention relates to a numerical control device for transfer machines that control multiple transfer machines installed in a transfer line. The numerical control device is comprised of an NC part (13) that controls the spindles of the transfer machines, and a PMC part (14) that executes sequence control. The PMC part (14) reads the current position data from a current position register (16) through a window for comparison operation with a pre-set area data (19). A functional instruction (18a) executes the alteration control of the execution sequence using the operation result as an area signal, thereby setting of a highly accurate area signal is made possible.
