摘要： The present invention pertains to a tracer control system for a system performing tracing in an arbitrary direction using a combination tracer control-numerical control unit which is a combination of a tracer control unit and a numerical control unit, and is intended to increase the cutting accuracy and cutting speed by controlling the feed by tracer control, as compared with a conventional system which controls the feed by numerical control.The numerical control unit is provided with a signal generating device, such as a controller, for generating a signal representing the angle of a feed shaft according to numerical information indicating a path of cutting. The tracer control unit is provided with a first coordinate transformation circuit which generates a displacement component signal in the direction of the feed shaft and a second coordinate transformation circuit for converting, according to the output of the signal generating device, a signal representing the velocity in the direction of the feed shaft into signals for controlling feed rates along the X-axis and the Y-axis. Thereby feed along the X-axis and the Y-axis is controlled by the output of the coordinate transformation circuit.

摘要： A method and apparatus for sensing the present position of a movable machine element in a position control system when a position control loop in the system is placed in the open state. In the position control system, error storage means computes and stores an error which corresponds to the difference between a command value produced by a control unit and an amount of movement sensed by a position sensor provided on a motor shaft or on the movable machine element. A speed control circuit controls the motor in accordance with the error from the error storage means. The method of sensing the present position includes the steps of reading and storing the error from the error storage means as a steady deviation immediately before the position control loop is switched from the closed to the open state, reading the error in the error storage means when the position control loop is in the open state, updating the content of a present position register on the basis of an arithmetic difference obtained by subtracting the steady deviation from the error read from the error storage means when the position control loop is in the open state, and revising the content of the error storage means in dependence upon the arithmetic difference.

摘要： An apparatus and a method for laser machining with a gap or tracing control, capable of shortening time required for moving a machining head from a machining end point of one machining shape to a machining start point of next machining shape. The laser machining is performed with the gap or tracing control in which a gap amount between the machining nozzle and the workpiece is controlled to be constant. Driving of a Z-axis is started at a predetermined velocity when the machining nozzle reaches a machining end point of one machining shape. In the drive of the Z-axis, when the Z-axis is driven by a predetermined amount, driving of an X-axis and a Y-axis is started so that the machining nozzle moves to the next machining start point by rapid traverse. A direction of driving of the Z-axis is reversed at a middle point between the machining end point and the machining start point. The driving of the Z-axis may be discontinued at a retreated point. When the gap amount reaches a predetermined amount, the gap control is started. A length of the motion path from the machining end point to the machining start point is made shorter and frequency of stopping/switching operation of the gap control axis and the machining feed axes is reduced to shorten a time required for the transition to the machining start point of the next machining shape.

摘要： A laser machining apparatus capable of effecting a feedback control of a laser output from an early stage of operation and detecting an abnormality of the laser output quickly and precisely. A laser output command issued from a laser output commanding section is subjected to a feedback control and inputted to a laser pumping power supply for a laser oscillator. An output of a laser power sensor is amplified by an amplifier and compared with an output of a measurement simulating section for estimating the measured value of the laser output. A difference of the measured value and the simulated value of the laser output is inputted to the feedback control section and also to an output abnormality detecting section. A measurement input estimating section calculates an average power which should be outputted in a normal condition of the laser machining based on data of the laser output command. A fist order delay system can be adopted as the measurement simulating section. The laser output abnormality detecting section determines whether or not the difference of the measured value and the simulated value is within an allowable range for the detection of an abnormality of the laser machining.

摘要： A maintenance schedule monitoring device is provided for a laser beam machine system, which is designed to monitor the maintenance schedule of the laser beam machine system. A time measuring unit (A) measures the time for which an object requiring maintenance is operating, according to information on the operation of the object requiring maintenance in the laser beam machine system. A time alarm unit (B) detects that the measured time has reached a preset time, and causes a maintenance schedule display control unit (C) to display an instruction that it is time to carry out a maintenance of the object, on a display unit (D). Thus, the maintenance and inspection schedule of the object requiring maintenance is automatically managed by automatic chronological time measurement, and when it is time to carry out the maintenance and inspection, an indication that it is time to carry out the maintenance of the object requiring maintenance is automatically shown on the display unit (D).

摘要： A three-dimensional shape machining laser device for performing three-dimensional machining. The device comprises a teaching box (20) for teaching NC commands, a sensor (43) for detecting the distance between the distal end of a nozzle and a work, a control apparatus (10) which includes command storage apparatus for storing the NC commands, NC command execution apparatus for executing the NC commands, tracing apparatus for controlling the gap between the nozzle and the work to a predetermined value, interrupt control apparatus for interrupting the execution of an NC command program, correction value calculation apparatus for calculating correction command values used for correcting coordinate values, and correction apparatus for correcting command values in accordance with the correction command values, etc. Tracer control is performed during execution of the NC commands, and when an amount of deviation from a path according to the NC commands exceeds a predetermined value, correction values are inserted to correct the path. Alternatively, the NC commands are executed without performing the tracer control. When an amount of deviation of the gap exceeds a predetermined value, correction values are inserted to correct the path. Teaching data can therefore be easily checked for accuracy and corrected, whereby reliable teaching data can be obtained.
