摘要： A laser beam machining method capable of preventing the occurrence of a notch portion (burn-through) at a machining terminating point on a product even when a work is machined into a shape in which a machining starting point and machining terminating point agree with each other, and an apparatus used therefor. A boring and periphery machining operations are started with a boring operation at a point P, and a cutting operation is then carried out from the point P to a point Q. A periphery machining operation is started at the point Q, and this cutting operation is carried out along a path 40 up to a point R. At the point R, the machining conditions are changed, and the laser beam reaches a point S, at which the periphery machining operation is completed. In order to carry out this boring and periphery machining operations, a CNC (10) subtracts a very short distance DELTA L1 between the points Q, S from a one-round machining path which starts at the point Q, to generate the machining path 40, which is then stored in a memory. This very short distance DELTA L1 is set to such a level that permits the portion of the work which is on the inner side of the periphery thereof to be removed speedily at the time of completion of the periphery machining operation. Since the machining finishing point S is set by subtracting the very short distance DELTA L1 from a one round machining path without having the starting and finishing points Q, S of the periphery machining operation agree with each other, the occurrence of a notch portion, which is encountered in a machining operation in which the starting and finishing points Q, S agree with each other, can be avoided.
摘要翻译：即使将加工成加工起点和加工终止点一致的形状，也能够防止产品的加工终点处的切口部（直通）发生的激光加工方法，以及用于其的装置。通过点P处的镗孔操作开始钻孔和周边加工操作，然后从点P到点Q执行切割操作。在点Q开始周边加工操作，并且该切割操作是沿着路径40直到点R.在点R处，改变加工条件，并且激光束到达周边加工操作完成的点S. 为了进行这种无聊和周边加工操作，CNC（10）从点Q处开始的单向加工路径中减去点Q，S之间的非常短的距离DELTA L1，以产生加工路径40 ，然后将其存储在存储器中。这个非常短的距离DELTA L1被设定为使得在周边加工操作完成时能够快速地移除在其周边的内侧的工件的部分的水平。由于通过从一个圆形加工路径减去非常短的距离DELTA L1而不使周边加工操作的起点和终点Q，S彼此一致来设定加工精加工点S，所以出现切口部分，其中可以避免起点和终点Q，S彼此一致的加工操作中遇到的。

摘要： A gap condition detector (3) detects a discharge machining condition of the gap between a tool electrode (1) and a work (2). The difference between this detection value Vg and a target value Vs is multiplied by axial components of a direction vector a &cir& _ in a retreating direction so as to obtain retreat speed command V2x to V2z. These values are added to speed commands V1x to V1z obtained by position loop control to obtain speed commands for speed loop control, and servo-motors (6x to 6z) are driven to regulate the gap described above. The retreat speed commands V2x to V2z are integrated by integrators (10x to 10z) to obtain the displacement of the tool when the speed commands are corrected. This displacement is added to the movement command inputted to the position loop, so as not to lose track of the tool.

摘要： In a method for effecting precision laser machining to a work by a laser machining head through additional operation shaft means (8) mounted to a robot body (1) of a multi-joint type laser robot, a required time (A+B) for taking the machining head by rapid feed from an origin point (OR) to a machining start point (E) according to various machining specifications stored in a rewritable storage means and a required time (C) for taking it similarly to the starting point without using rapid feed are calculated and compared with each other by arithmetic means (CPU) provided to a robot controller (10) of the laser robot. Only when the required time (A+B) is shorter than the required time (C), a rapid feed command is given automatically to driving motors (MA, MB) of the additional operation shaft means (8) so that the rapid feed operation of the laser machining head becomes effective to a predetermined laser machining trajectory. In this way, judgement is made automatically and laser machining efficiency can be improved.

摘要： A variable reluctance motor is driven by a circuit comprising a common switching element, and switching elements which correspond to the phases. The total value (total current it) of the currents flowing through the phase coils is found. In accordance with the difference between the total value and a current command icmd, and its sign (positive or negative), the duty ratio of the PWM signal for turning the common switching element on and off is calculated. Further, based on which phase is excited according to the electrical angle of the rotor, and on the sign of the difference, the turn on/off of the switching element corresponding to each phase is controlled. In this way, a current loop is controlled to permit the detected total current it to follow up the current command icmd. Therefore, even when the excited phases are switched over, the current is always controlled to suppress the torque ripple.
