    摘要: A motor driving apparatus applicable to various types of motor driving apparatuses and having a power storage section for storing a regenerative current and supplying power to an inverter section at the time of acceleration. The motor driving apparatus further comprises a converter section, a DC link, and an inverter section, thereby driving a motor. Connected to the DC link is the power storage section including a capacitor, a charging circuit, a discharging circuit and a diode. The regenerative current produced at the motor deceleration is stored in the capacitor through the diode. The power stored in the capacitor is outputted to the DC link by turning a switching element of the discharging circuit ON at the motor acceleration. Furthermore, the charging circuit has a boost switching regulator circuit for charging the capacitor to the given upper limit voltage equal to or larger than voltage of the DC link and a current limitation circuit for limiting a charging current to the given upper limit. The upper limit of the charging current can be changed according to the type of the motor driving apparatus.

    摘要: A method for adjusting the gap between an upper nozzle of a wire electric discharge machine includes placing a spacer member of a known thickness between a forward end of the upper nozzle and a workpiece. The forward end of the upper nozzle is brought into contact with the spacer member, so that the forward end of the upper nozzle is prevented from coming into direct contact with the workpiece. A Z-axis position of the upper nozzle is controlled on the basis of the thickness of the spacer member and the desired nozzle gap to set the gap between the forward end of the upper nozzle and the workpiece to a predetermined value. In controlling the Z-axis position of the upper nozzle, correction is made to compensate for a deformation of the upper guide, the spacer member, the workpiece, and the upper nozzle, and/or for a displacement of the upper guide resulting from a pressure of a working fluid.

    摘要: A laser machining apparatus in which laser output can be easily corrected in view of secular change of components of the laser machining apparatus and influence of temperature. Output values of a laser oscillator operated according to a reference laser output command value Psc are stored as reference output values P(null) at different temperatures null in a table TB1. When the laser oscillator is started up, a measured output value Pr of the laser oscillator supplied with the reference command value Psc is obtained, and a new correction coefficient k is obtained to replace an old one. From a reference output value P(null) at a temperature at that time and the actual output measured value Pr, a correction value nullP is obtained and stored. Each time temperature null is measured, a reference output value (Pnull) at a measured temperature null is obtained from the table TB1, an estimated output value Pa is obtained by subtracting the correction value nullP from the reference output value (Pnull), and a new correction coefficient k is obtained to replace an old one. In other words, an output value at a different temperature is estimated on the basis of the correction value nullP obtained when the laser oscillator is started up, and a new correction coefficient k is obtained to replace an old one. When the temperature reaches a predetermined temperature, a new final correction coefficient k is obtained on the basis of the reference command value and a measured output value to replace an old one.

    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: If a machining program is reproduced in a robot controller and a robot is moved on a machining route, then a detection signal of a distance sensor is fetched through a distance sensor amplifier, and tracer control is carried out so as to keep a distance between a laser machining head and a workpiece at a predetermined value. In an acceleration and decoration processing in a corner, a restriction means that restricts a maximum acceleration and a maximum jerk is used to control an acceleration and a jerk of the robot not to exceed respective predetermined values, and prevents generation of a vibration when the laser machining head passes through the corner.

    摘要: An offline programming system making it easy to perform operations for correcting a positional deviation produced when a program, to which taught points have been added or position/orientation modifications have been made offline, is applied to a robot. A program P1 prepared by the offline programming system is applied to the robot, and a program P2 for which corrections of position deviation have been made is read in from a robot controller. Correction amounts E are each determined from a position/orientation deviation between corresponding taught points of the programs P1, P2. A program P3 is obtained by adding taught points to the program P1 or modifying taught points thereof. Expected correction amounts for the added or modified taught points are each calculated from the correction amounts of existing taught points near the position of the added or modified taught point. A program P4 obtained by modifying taught points in the program P3 using corresponding correction amounts is output to the robot controller which can easily correct actual position/orientation deviations because even the added or modified taught points have been modified with the expected correction amounts.

    摘要: When die machining including machining processes from a rough machining process to a finish machining process is carried out on the same workpiece along a closed machining path, each of the points equally dividing a length of the closed machining path by the repetition number of machining processes is defined as an approach point, so that the approach points are different from each other for each machining process. This makes it possible to avoid a concentration of the approach points at one points thereby preventing a dent from being formed at the approach point.
