摘要： A machine tool is fitted with a position detector for detecting a position of a moving axis of the machine tool and an on-machine measuring device for measurement on the machine tool. An axial position detection signal output from the position detector and a measurement signal output from the on-machine measuring device are received through interfaces by a numerical controller that controls the machine tool. These interfaces are designed so that the numerical controller receives the axial position detection signal and the measurement signal with the same timing.

摘要： In a machine tool having an on-board measuring machine and controlled by a numerical controller, a method of measuring a shape of a workpiece presets a reference point for temperature drift correction on the workpiece, moves a probe to the reference point, resets a coordinate system of the probe to correct a temperature drift of the probe, and carries out shape measurement of the workpiece along a first measuring path. Next, the method moves the probe to the reference point again, resets the coordinate system of the probe to correct a temperature drift of the probe again, and carries out shape measurement of the workpiece along a second measuring path. Thereafter, similar temperature drift correction is carried out for each measuring path until the shape measurement of the workpiece is carried out along the last measuring path.

摘要： A measurement program is created for measurement performed by moving X- and Z-axes so that a central axis of a probe is perpendicular to the surface of a reference sphere, and errors are obtained between original probe position data and probe position data obtained by measurement performed at two different angles θ1 and θ2 of a rotary axis according to the created measurement program. Position coordinates of a tip end of the probe at the two different angles θ1 and θ2 of the rotary axis are corrected so that the errors are zero. Then, the X- and Z-axis coordinates are corrected based on a positive or negative phased shift amount, and measurement errors are obtained by calculation. A real probe tip position is defined by the X- and Z-axis coordinates corrected by a correction amount with which the obtained measurement errors become minimum.

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： A machine tool capable of automatically correcting an orientation of a workpiece or machining attachment based on detection results from position detectors that the machine tool inherently has. The machine tool comprises: position detectors; position deviation determining means; contact detection means that detects a contact between a probe and a surface of the workpiece or the machining attachment based on a position deviation; movable axis stopping means; coordinate value detection means; inclination determining means; and correction means. The inclination determining means moves linear axes to perform detection of contacts between the probe and the surface of the workpiece or the machining attachment at least two different points, and determines an inclination of the workpiece or the machining attachment using the obtained coordinate values. The correction means corrects a mounting error of the workpiece or the machining attachment, or corrects the machining program based on the determined inclination.
