摘要： When an operation state of a numerical controller which controls a machine tool is (1) in a state were rotation of a spindle is being stopped, (2) in a state where cutting feed rate of a tool with respect to a work exceeds a set maximum cutting feed rate corresponding to a work material, or (3) in a state where the tool moves in a direction different from the work cutting direction of the tool, it is checked whether or not the tool and the work interfere with each other. In other operation states, an interference check is not executed.

摘要： Any commands, selected in a program, are set as a reference time data command, an elapsed time data command and a time data command. The program is read and original processing of the commands is performed, and if the reference time data command is read, a time then is stored as a reference time. If the elapsed time data command is read, elapsed time from the reference time is acquired and stored as execution elapsed time. If the time data command is read, the time then is stored as an execution time. Thus, it is possible to easily check the execution time of any program command.

摘要： A numerical controller that shortens time required for transferring control of a spindle between control systems. When the spindle control command is included, the command is carried out and information on designation of the spindle, commanded rotational velocity and direction is stored in a case of a velocity control mode, and information on designation of the spindle, commanded rotational position and velocity is stored in a case of a position control mode. When a command to cancel the control of spindle is read, the control of the designated spindle and also the stored information on the control status of the spindle are transferred to the other control system. A command to acquire the control of the spindle is read in a machining program for the other control system, the control of the designated spindle is started by the other control system according to the transferred control status of the spindle.

摘要： A pulse distribution unit notifies a mode control/instruction unit of an output start signal. The mode control/instruction unit outputs a mode setting signal, a speed command signal, and a compensation pulse to an axis control unit. In a position control mode, the mode control/instruction unit continues outputting the speed command signal to the axis control unit until the mode control/instruction unit receives the output start signal from the pulse distribution unit, and stops, up receiving the output start signal, outputting the speed command signal. The compensation pulse is output to the axis control unit to cancel the difference between a spindle position and the position control start reference position of the spindle. The axis control unit adds the compensation pulse to the position command signal of the spindle output from the pulse distribution unit and outputs the result to a servo control unit.

摘要： A numerical controller which has a plurality of command systems and controls a machine having a plurality of spindles, and in which a program can be prepared without taking account of the correspondence between the command systems and the spindles. The numerical controller has n number of command systems and controls a machine tool or the like that has n number of spindles and a required number of other axes. A signal indicative of the correspondence between each command system and a spindle is inputted from external signal input means to a selecting/switching section. The selecting/switching section selects, among the spindles 1 to n, a spindle of a destination such as a command S1 for spindle control outputted by each command system in response to the input signal by software processing. The position of a tool or a workpiece to be machined can be changed in accordance with a change of the correspondence between the command systems and the spindles.

摘要： A laser oscillator includes a housing which seals a laser medium gas from the atmosphere, concave mirrors (or a set of concave and convex mirrors) positioned in the housing and having the laser medium gas therebetween, an apertured mirror positioned between the concave mirror and the other concave or convex mirror on a line connecting the spherical centers of the mirrors at a predetermined angle relative to the line, and a window through which a laser beam reflected by the apertured mirror is output from the housing. The apertured mirror has a curved reflective surface, thereby simplifying the optical system in the housing and increasing the system's reliability.
