摘要： A single machining program including turning and milling program steps together with a turning mode command or a milling mode command is stored in a program memory. When the turning mode command is read out from the program, a numerical control apparatus analyzes the program according to a G code architecture for lathe by numerical controller #1 for turning to control servo motors and a spindle motor. When the milling mode command is read out from the program, the apparatus analyzes the program according to the G code architecture for milling by a numerical controller #2 for milling to control the servo motors and the spindle motor.

摘要： A numerical control device for synchronously controlling the movement of a plurality of axes of a machine by repeatedly controlling a cyclic motion. An axis of the machine is designed to stop at a predetermined position upon the occurrence of an emergency stop. To achieve this stop position, an amount of retraction is set up to a position where a tool of machine does not interfere with a work piece or other obstacles. When an emergency stop signal is entered during a binary operation, because of an occurrence of an abnormality, a movement control amount for each period, corresponding to a set amount of retraction, is added to the movement control amount for each period of the binary operation and the axis is thereby driven by the resultant modified movement control amount. The binary operation is stopped upon the reaching of the stop position, and the tool can be held at this retracted position, by the set amount of retraction. Thus, the tool can be retraced to a predetermined position where it does not interfere with either a work piece or another obstacle.

摘要： For outputting an amount of backlash compensation according to the direction of reversal in the reversal motion of the moving axis, three output modes are prepared: (a) a mode in which a preset backlash compensation is outputted all at once, (b) a mode in which backlash compensation is outputted according to distance traveled, and (c) a mode in which backlash compensation is outputted according to time elapsed. It is determined whether the motion of the moving axis has been changed from positive to negative directions or from negative to positive directions, and with this determination result, any one of the above three output modes (a) to (c) is selected.

摘要： A numerical controller that can easily set parameter values related to servo control used within itself. Machine constants are set in the numerical controller. The numerical controller calculates the parameter values related to the servo control used in the numerical controller, from the set machine constants, and stores and sets them in a memory means within the numerical controller. The parameter values calculated are also fed to an output device such as a display device for an operator to check them. When a machine to be controlled by the numerical controller is determined, the machine constants can be easily obtained from the specifications or the like of the machine and set in the numerical controller. Since the numerical controller itself calculates and sets the parameter values related to the servo control, the setting can be easily carried out without full knowledge of the internal elements, structure and operation principle of the machine, the processing performed by the numeric control unit, etc.

摘要： When a read block includes a code for setting a machine coordinate system used for exchanging a tool or the like, it is determined whether a feed rate specifying modes, set by a parameter, is (a) specification by using parameters, (b) specification by a program, or (c) specification by using an external signal input. In mode (a), the rapid traverse speed set for movement according to machine coordinate system or different feed rate set by a parameter is selected and set as feed rate F. In mode (b), a feed rate specified by a program is set as feed rate F. In mode (c), an input signal is converted into a speed which is set as feed rate F. Then the movement command according to the machine coordinate system is executed with this set feed rate F.

摘要： Foreground program execution means executes a program, and outputs movement commands to a control object. Meanwhile, background program execution means checks abnormalities by executing the program, without outputting the movement commands, obtained by executing the program, to the control object. If a program abnormality is detected by the background program execution means, the abnormality is stored in association with the block in which the abnormality is detected. When the program is executed by the foreground program execution means, the program is interrupted at the end of a preceding block for which a program abnormality was stored.

摘要： A numerical controller controls an object for movement along a movement path according to a machining program. If consecutive command blocks are oriented in the same direction, they are set as a single vector. These three consecutive vectors (first, second, and third vectors) thus created are determined to be located at a pick-feed section if the first and third vectors are oriented in the same direction and if the length of the second vector is within a predetermined range. The movement path is corrected to a path that successively linearly connects the start point of the first vector, points on the first and third vectors, and the end point of the third vector.

摘要： A motor control system capable of securing stability and rapidity of motion even in a machine where the stability varies in accordance with a position of a driven member. The driven member and a motor for driving the driven member are operatively connected through a transmission mechanism including a nonlinear element such that a rate of change of the position of the driven member with respect to the position of the motor varies in dependence on the position of the motor. Optimum values of multiplier factors of operation constants with respect to the position of the driven member or the rotational position of the motor for the position control and the velocity control are stored in a data table. The values of the multiplier factors of the operation constants for a present position of the driven member or a present position of the motor are determined using the data table and the determined values of the multiplier factors are multiplied by reference operation constants to update the operation constants. The position and/or velocity control processing is performed using the updated optimum operation constants in accordance with the present position of the driven member or the present rotational position of the motor.
