    Abstract: 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.

    Abstract: A shape measurement data is acquired by measuring along a spiral measurement path a lens shape which is machined along a spiral machining path. An interpolated shape measurement data at intersecting points of a radial line passing through a center of the lens shape and the spiral measurement path is acquired by interpolating the shape measurement data, and a compensated machining amount for removing a machining error at each of the intersecting points (the machining points) is calculated from the interpolated shape measurement data by interpolation. Further, a machining point compensated machining amount at each of the machining points on the spiral machining path is calculated from the calculated compensated machining amount, and a compensated machining path is created on the basis of the machining point compensated machining amount.

    Abstract: A machine tool having an onboard measuring device automatically carries out various works which include ultra precision machining, washing and onboard measuring, by a numerical controller, without any interposition of a worker. For achieving this, an operation region of drive axes of the machine tool is previously divided into a machining region, a washing region and a measuring region. Positions of the drive axes are always monitored by the numerical controller, and when the drive axes enter each of the regions, a work allocated to each of the regions is automatically started and the work is continuously carried out until drives axes exit the region.
