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.
A processing method, comprising:
An object having a workpiece surface made of a material containing metal, the object comprising a V-groove pattern formed in a predetermined area on the workpiece surface, the V-groove pattern having a plurality of grooves of a V-shaped cross-section which are formed at intervals of a constant pitch, wherein an angle of a groove face of the groove is gradually varied depending on a position of the groove so that a uniform color is visually recognizable in every location in the predetermined area when the predetermined area is observed from a predetermined viewpoint.

This application is based upon and claims the benefit of priority from Japanese Patent Application No. 2019-206632 filed on Nov. 15, 2019, the contents of which are incorporated herein by reference.
The present invention relates to a processing method and an object.
Japanese Laid-Open Patent Publication No. 2010-012520 discloses a processing method in which a surface of a solid material (workpiece) is cut by moving a processing tool in a pulse-driven state relative to the surface of the workpiece and bringing them into contact with each other, thereby forming a fine structure on the surface of the solid material. In Japanese Laid-Open Patent Publication No. 2010-012520, drive pulses generated at a fixed time interval are applied while the processing tool and the processed object (workpiece) are being moved at a fixed relative speed, whereby fine grooves are formed at equal intervals.
FIG. 1 is a perspective view showing part of an ultra-precision processing machine that can be used in a processing method according to an embodiment;
FIG. 2 is a block diagram showing the ultra-precision processing machine that can be used in the processing method according to the embodiment;
FIG. 3 is a diagram showing a mechanism by which a specific color is visually recognized;
A processing method and an object according to the present invention will be detailed below by describing a preferred embodiment with reference to the accompanying drawings.
A processing method (machining method) and an object according to an embodiment will be described with reference to the drawings. FIG. 1 is a perspective view showing part of an ultra-precision processing machine that can be used in the processing method according to the present embodiment.
As shown in FIG. 1, an ultra-precision processing machine (precision processing machine) 10 has a base 12. The base 12 is fixed at an installation position of the ultra-precision processing machine 10.
