Abstract: A cam plate type axial piston pump capable of operating a control lever operatively connected to a cam plate to control an inclination angle of the cam plate and control its discharge depending on the inclination angle. A piston pump of such type exhibits self-return force toward a position nearer its neutral point when it reaches a position near the neutral point. The pump of the present invention is so constructed that a thrust plate provided on a cam plate is pivotally moved in order to positively utilize the self-return force.

Abstract: An apparatus in which a wire electrode is pulled off a supply reel, passes through a predetermined path, is led to the machining portion of a work piece to cut the work piece, thereafter, the wire electrode is turned back, is returned along the path it has come to the machining portion of the work piece, and is used again to work the same work piece. At least one of these two segments of the wire electrode is advanced in a zig-zag path along the machining line when the work piece is cut, thereby allowing the working gap to be widened for improving the efficiency and accuracy of machining.

Abstract: An EDM method and system in which a DC output is pulsed to produce a succession of discrete, time-spaced, essentially unidirectional current pulses of a short duration not in excess of 10 microseconds for finish-machining a workpiece with a tool electrode across a fluid flooded EDM gap, each of the discrete current pulses having an essentially half-cycle sinusoidally rising and falling current-time characteristic and a peak current in excess of a predetermined current level. According to the invention, a peak current portion of each of the current pulses beyond the predetermined level is clipped to produce a reformed gap current pulse which is substantially square- or trapezoid-edged and has the predetermined current level.

Abstract: This invention relates to improvement in a laser machining apparatus using both a working laser generator (101) and an auxiliary energy supplying apparatus (110) such as a plasma or the like. A feature of the invention is that an auxiliary energy generated from the auxiliary energy supplying apparatus is radiated on a workpiece (118) to a location which is slightly apart from an irradiation point of a working laser beam. In a preferred embodiment, the auxiliary energy supplying apparatus (110) is attached to a rotary disk (113) thereby allowing the auxiliary energy to be radiated to a location which is always preceding an irradiation point of the laser beam in the working progressing direction. The auxiliary energy may be radiated onto a surface opposite to the surface of a workpiece to which the laser beam is radiated. With such an arrangement, working efficiency and accuracy are improved and a structure of the whole system is also simplified, resulting in less failure. To further improve the working efficiency, in a desirable embodiment, an abrasive grain may be supplied to the working portion, or a high-pressure working fluid may be jetted thereto, or a working fluid to which an ultrasonic vibrational energy was applied may be supplied thereto. Further, a focal point automatic adjusting mechanism of the laser beam may be provided.

Abstract: A grinding wheel capable of detecting and a method of monitoring it to detect, the development of a crack or like damage therein are disclosed. The wheel is constituted of an electrically nonconductive body having an electrically conductive strip, e.g. a thin film of an electrically conductive ink printed, of an electrically conductive paint applied, of a metal electrolessly or chemically deposited or of a metal electrolytically deposited, in a pattern, say, of quasi-circular or spiral configuration, on a portion of at least one side surface of the body. A current source is connected to the opposite ends of the conductive strip to pass an electric circuit therethrough. When a crack or like damage develops in the wheel body being rotated to perform a grinding operation, the circuit will be broken or a change in the current will occur, signaling the damage or crack formation.

Abstract: A capacitor-type power supply for electrical machining has a capacitor connected across a machining gap while a high-frequency power generator is disposed at a location remote from the machining gap and provides a high-frequency electric power. A feeder connects the power generator with the capacitor to permit the capacitor to be charged with pulses of the high-frequency electrical power. The system permits the high-frequency source to be located distally from the machining gap.

Abstract: A drive mechanism for a machine such as a machine tool or robot includes a rotatable shaft, e.g. a lead screw or spindle, drivingly connected with a movable element, e.g. a worktable or tool support, in the machine, a drive shaft for rotation by a motor and a coupling unit, e.g. clutch or gear transmission, for drivingly connecting the drive shaft with the rotatable shaft to move the movable element in a predetermined form of movement under a variable load in the machine. Encoders are provided in a rotation-sensing relationship with the drive shaft and the rotatable shaft, respectively, to feed two trains of rotation-responsive pulses into a differential counter which provides a difference in angle of rotation signal representing an instantaneous torque produced at the drive coupling unit between the drive and rotatable shafts. The differential signal and a preset signal set in a setting circuit, representing a predetermined value of torque are processed in an output circuit which produces a control signal which is used to control the motor or the coupling unit so as to maintain the torque between the drive and rotatable shafts substantially at the reference value.

Abstract: An NC-EDM machine is safeguarded against feed errors arising from both mechanical and erosive-machining effects. The disclosed safety arrangement includes two detecting circuit units. The first unit is arranged to respond to NC-furnished driving command signals for producing a first detection signal representative of a commanded relative displacement to be effected between the tool electrode and the workpiece along a programmed machining path in a given time period. The second detecting unit is arranged to respond to effective electrical discharges caused in the EDM gap to produce a second detection signal representative of an actual relative displacement effected between the tool electrode and the workpiece along the path in the given time period. A comparator is connected to the two detecting units for comparing the first and second detection signals to produce an output signal indicative of a deviation of the actual advancement from the commanded advance.
