摘要： PROBLEM TO BE SOLVED: To provide a machining apparatus and a machining method, for machining according to a machining model simply and accurately while varying the contraction scale in the height direction. SOLUTION: A non-contact displacement gauge 3 is fitted to one surface of a tool table 1. A tool 2 is fitted to the other surface thereof. A machining model 5 is disposed opposite to the displacement gauge 3. A work 6 is disposed opposite to the tool 2. The displacement gauge 3 measures the distance to the machining model measured by a probe 3a, and sends an output signal. The output signal is amplified by an amplifier to drive an actuator for projecting the tool 2. The degree of amplitude of the amplifier is made adjustable. Thus, the contraction scale in the direction of height is varied to the machining model 5 to machine the work. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To monitor displacements between a movable scale and a fixed slit of an optical encoder and excess load related to the displacements without having to use a separately placed displacement sensor. SOLUTION: Light from a light source part is irradiated to the movable scale 1 mounted to a rotating shaft etc. of a fluid bearing motor to generate signal light of an A phase, a B phase, etc. The signal light of each channel is passed through each opening of the fixed slit and made incident onto a light receiving part to generate an electric signal of each phase. The peak of output Vin of any phase is held by a peak hold element and compared with a peak voltage Vref at normal times to acquire an output voltage Vo as monitor output. On the basis of a code and an absolute value of Vo, it is possible to monitor displacements of the movable scale and a rotor in directions along the rotating shaft or the size of load (an external force) exerted on them and detect anomalous displacements, excess load, etc. COPYRIGHT: (C)2005,JPO&NCIPI

摘要： PROBLEM TO BE SOLVED: To reduce an electromagnetic torque ripple, to obtain excellent characteristics to biased load, to improve the positional accuracy of a winding and to miniaturize size in the axial direction.
SOLUTION: When a member constituting an air bearing is arranged on the fixing side of the motor 1, the uniformity of a magnetic field forming the torque of the motor 1 is maintained by disposing the components of the air bearing so as not to disturb the reluctance distribution of the magnetic core of the motor 1, and an electromagnetic torque ripple is reduced. The fixing side is formed in slotless structure in the above-mentioned arrangement, and a mechanical structural torque ripple is decreased. In the above-mentioned arrangement, configuration in which the components (an opening and a gas duct) of the air bearing having an effect on the magnetic characteristics of the motor 1 are positioned at places separate from the magnetic core can be formed. In the configuration, the gas duct and the opening in the components of the air bearing are disposed at places separate from the magnetic core.

摘要： A machining apparatus capable of irregularly forming a plurality of dimples on a surface of a workpiece in a short period of time. The machining apparatus includes a tool for machining a plurality of dimples on a surface of a workpiece, each dimple having a depth in a first direction; a drive unit for displacing the tool relative to the workpiece in the first direction and a second direction generally perpendicular to the first direction; a controller for controlling the drive unit so as to displace the tool relative to the workpiece in the first direction such that the tool cuts into or leaves the workpiece, while the tool is being moved relative to the workpiece in the second direction, wherein a trigger of the displacement of the tool in the first direction is timing calculated by using a second waveform, the second waveform being determined by comparing the magnitude of a first waveform with a predetermined threshold, at least one of frequency and amplitude of the first waveform being irregular.

摘要： An ultra-precision machine tool capable of accurately detecting a machining start position, in which movable axes are supported by fluid bearings. A workpiece is mounted on a rotary table of a B axis, and the rotary table is mounted on an X axis that is a linear motion axis. A tool is mounted on a Y axis. The Y axis is mounted on a Z axis. The X axis is moved reciprocally each time the Z axis is moved a predetermined amount, a machining surface of the workpiece is scanned, and it is determined whether or not position deviation of the X, Y and B axes reaches or exceeds a reference value. The Y axis is driven and the tool is moved toward the workpiece a predetermined amount, and the above-described scan is performed. When the position deviation of the X, Y and B axes reaches or exceeds the reference value it is determined that contact between the tool and the workpiece has occurred, and this contact point is stored as the machining start position, the Y axis is skipped, and the tool is moved a predetermined amount in a direction away from the workpiece, thus enabling a point of maximum protrusion from the machining surface of the workpiece to be simply detected as the machining start point.

摘要： An air balance structure that compensates for the weight load of a movable member driven in a straight line along the vertical axis, with a simplified structure and at reduced cost. The box-shaped movable member has an open bottom that accommodates the stationary member therewithin, in which state the movable member is movably supported in the vertical direction by an air bearing created using a gap between the stationary member and the movable member. An air balance chamber that contains pressurized air is formed inside the movable member. After pressure-adjusted air is supplied from the outside to the gap from a jet port through a pipe inside the stationary member, the air flows into the air balance chamber. This flow seals the pressurized air inside the air balance chamber. Pressurized air exhaust is exhausted externally from an exhaust port through a pipe and a flow adjusting device.
