Abstract
A method of manufacturing a watch component according to the present disclosure is a method of manufacturing a watch component that includes a decorative region at a front surface thereof. The method includes sequentially irradiating the decorative region with laser light to draw, in a superimposed manner, a plurality of decorative patterns constituted by a plurality of lines. At least one of the decorative patterns is constituted by the plurality of lines arranged at intervals in a range of 80% to 200% of a spot diameter of the laser light, at least one of the plurality of lines including a curved portion.
Claims9
A method of manufacturing a watch component including a decorative region at a front surface thereof, the method comprising:
- irradiating the decorative region with laser light to draw a first decorative pattern constituted by a first plurality of lines;
- after drawing the first decorative pattern, irradiating the decorative region with the laser light to draw a second decorative pattern constituted by a second plurality of lines, the second decorative pattern being superimposed on the first decorative pattern;
- and
- after drawing the second decorative pattern, irradiating the decorative region with the laser light to draw a third decorative pattern constituted by a third plurality of lines the third decorative pattern being superimposed on each of the first decorative pattern and the second decorative pattern,
- wherein at least one of the first, second, and third decorative patterns is constituted by the plurality of lines arranged at random intervals in a range of 80% to 200% of a spot diameter of the laser light, at least one of the plurality of lines including a curved portion.
A method of manufacturing a watch component including a decorative region at a front surface thereof, the method comprising:
- sequentially irradiating the decorative region with laser light to draw, in a superimposed manner, a plurality of decorative patterns constituted by a plurality of lines,
- wherein at least one of the decorative patterns is constituted by the plurality of lines arranged at random intervals in a range of 80% to 200% of a spot diameter of the laser light, at least one of the plurality of lines including a curved portion;
- at least one of the decorative patterns includes a divided section where at least one of the plurality of lines is divided, and a length of the divided section is random;
- of the at least one line including the divided section, a line having a length no more than a first threshold value is rounded into a curved shape to form a rounded portion;
- and
- of the at least one line including the divided section, a line having a length no more than a second threshold value smaller than the first threshold value is erased.
A method of manufacturing a watch component including a decorative region at a front surface thereof, the method comprising:
- sequentially irradiating the decorative region with laser light to draw, in a superimposed manner, a plurality of decorative patterns constituted by a plurality of lines,
- wherein at least one of the decorative patterns is constituted by the plurality of lines arranged at random intervals in a range of 80% to 200% of a spot diameter of the laser light, at least one of the plurality of lines including a curved portion;
- and
- wherein an output of laser light is adjusted to be greatest when laser light irradiation is performed along a decorative pattern having a largest interval between the lines among a plurality of decorative patterns.
