摘要： Voltage fluctuating time integrating means integrates voltage fluctuating time when voltage of a sensor electrode fluctuates as a voltage fluctuation integrated time, and voltage fluctuation occurrence rate computing means computes a rate of occurrence of voltage fluctuation for time on the basis of the voltage fluctuation integrated time integrated. By doing so, quantity of generated plasma can be taken as the rate of occurrence of voltage fluctuation, and plasma detection judging means can easily detect large volume of generated plasma on the basis of the computed voltage fluctuation occurrence rate. Then, it is not necessary to provide a circuit for measuring electric resistance between the sensor electrode and a workpiece as a conventional way, thereby avoiding complexly structured plasma detector.

摘要： A sensor 42d is provided for detecting release of a state of a workpiece fixed and held with workpiece holding members during rotation of a spindle 9. When the release of the state of the wokpiece fixed and held is detected, the sliding members are driven in a direction of an axial center (in a direction as shown by an arrow D) by a reciprocating drive means 42. Even if holding force, such as the oil pressure of the workpiece holding member, is lowered, the decrease of the holding force of the workpiece can be extremely avoided by moving the sliding members in the direction of the workpiece.

摘要： A laser processing unit includes a torch that is automatically mounted on a processing head. The torch has an assist gas chamber and a balance chamber, and the assist gas is supplied to the chambers. Constantly, equal pressures act on the both chambers, and an upward first force and a downward second force that act on a lens holder offset each other because pressure reception areas are equal. Gas is supplied to a gas spring chamber to provide a constant upward force to the lens holder. A driving device has an arm driven by a servomotor. The arm is in contact with a pin and the lens holder is moved to a predetermined position for automatically adjusting a focus position FC of a collective lens.

摘要： The invention provides a method for fabricating a large sheet metal product having a three-dimensional shape such as a cover of a machine tool, without performing a welding process, and a product fabricated by the same. A cover unit 1 of a machine tool is fabricated by fixing to a circumference edge portion of a cover sheet 10 edge members 110, 120, 130, 210, 220, 230, 310 and 410 via fastening members such as bolts and nuts. The cover sheet 10 and each of the edge members are formed by nesting an expansion plan based on a three-dimensional solid model data of the cover unit 1 on a sheet metal material on a laser beam machine, and subjecting the same to laser processing. At this time, various information such as bend lines and bend angles required in the post process are marked off on each component via laser processing. The components having been subjected to high-precision laser processing are subjected to necessary bending process. The components are then assembled using fastening members to fabricate a large sheet metal product having a three-dimensional shape without performing a welding process.
