A processing method includes: a step of setting a workpiece having a workpiece surface made of a material containing metal, on a precision processing machine; and a forming step of forming multiple grooves having a V-shaped cross-section, at intervals of a constant pitch in a predetermined area on the workpiece surface, using a tool provided in the precision processing machine to thereby form a V-groove pattern made up of the multiple grooves, in the predetermined area. In the forming step, each time one groove is formed, the relative position between the tool and the workpiece is moved in a direction intersecting the longitudinal direction of the groove and the angle of the groove face of the groove is gradually varied so that a uniform color can be visually recognized in every location in the predetermined area when the predetermined area is observed from a predetermined viewpoint.

Processing method and object

An on-machine measurement device that locates a tip position of a blade of a machining tool provided on a machining device includes: a measurement unit configured to measure, in a workpiece that has been machined by the machining tool, a height of a reference plane not machined by the machining tool and a height of a machined surface machined by the machining tool; and a locating unit configured to locate the tip position of the blade of the machining tool based on information on a machining depth specified at the time of machining of the workpiece, and the height of the reference plane and the height of the machined surface that are measured by the measurement unit.

On-machine measurement device, machine tool, and on-machine measurement method

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.

In a simultaneous multi-axis measuring machine tool system including linear drive axes and rotation axes to measure a surface shape of an object to be measured by using an on-board measuring device having a probe mounted, at one end thereof, with a spherical contactor, a numerical controller controls driving of the linear drive axes and the rotation axes so that a central axis of the probe is always oriented in a direction perpendicular to the surface of the object to be measured and that the spherical contactor of the probe comes in contact with and follows a surface of the object to be measured.

There is provided a contact type measuring instrument in which the contact force of a probe is adjusted by a force created by compressed air and an attraction force between a permanent magnet and a magnetic body. This measuring instrument gives a pulling-in force or a pushing-out force to the probe by controlling a fluid pressure in a probe body. Also, between the permanent magnet attached to the tip end of a movable part of a micrometer attached to the probe body and a plate-shaped member attached to the end part on the side opposite to a contact of the probe, an attraction force according to a distance between the permanent magnet and the plate-shaped member is created.

Contact type measuring instrument

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.

A plurality of electrostrictive elements,are located about the perimeter section of a table,. The table is fixed to a table fixing member,. The table fixing member,is prohibited from rotating by guide pins,. When a servo motor,&prime; constituting a rotational drive mechanism,is driven by passing a current through a stator,therein, the rotor,rotates. Thereby, the table fixing member,, which has a female screw thread,that engages with a male screw thread,formed in the rotor,, moves in a vertical direction. The table,also moves in a vertical direction and can be registered in a desired position. Inclination of the table,caused by processing errors in the male screw,and female screw,is adjusted to a horizontal position or a desired angle, by driving the electrostrictive elements
