Cutting support apparatus, cutting pattern generation method, and cutting system

A cutting system that generates a cutting pattern for cutting a plurality of plate parts that form a shoe last from a plate member and cuts the plurality of plate parts from the plate member based on the cutting pattern, the cutting system comprising:

• a cutting support apparatus configured to generate the cutting pattern;
• and
• a cutting apparatus configured to cut the plurality of plate parts from the plate member based on the cutting pattern computed by the cutting support apparatus, wherein
• the cutting support apparatus includes:
• a memory configured to store part information indicating a plurality of areas of subsets of the plurality of plate parts that form the shoe last;
• and
• a processor configured to:
• obtain shoe last data of the shoe last generated based on a three-dimensional foot shape data of a foot of a user,
• determine a plurality of cutting areas to be cut in the plate member corresponding to the plurality of areas of the subsets of the plurality of plate parts that form the shoe last based on the part information,
• determine, for each subset of the plurality of plate parts in each area of the plurality of areas of the plurality of plate parts that form the shoe last, an arrangement of cutting positions of the subset of the plurality of plate parts in the plurality of cutting areas based on an arrangement condition, and
• generate the cutting pattern,
• wherein the plurality of areas includes a foot width direction part of the shoe last and a malleolus part of the shoe last,
• the foot width direction part includes a toe part of the shoe last, an instep part of the shoe last, and an ankle part of the shoe last, and the malleolus part of the shoe last includes a medial malleolus part of the shoe last and a lateral malleolus part of the shoe last.

A cutting pattern generation method of generating a cutting pattern for cutting a plurality of plate parts that form a shoe last from a plate member, the cutting pattern generation method comprising:

• obtaining part information indicating a plurality of areas of subsets of the plurality of plate parts that form the shoe last;
• obtaining shoe last data generated based on a three-dimensional foot shape data of a foot of a user;
• determining a plurality of cutting areas to be cut in the plate member corresponding to the plurality of areas of the subsets of the plurality of plate parts that form the shoe last based on the part information;
• determining, for each subset of the plurality of plate parts in each area of the plurality of areas of the plurality of plate parts that form the shoe last, an arrangement of cutting positions of the subset of the plurality of plate parts in the plurality of cutting areas based on an arrangement condition;
• and
• generating the cutting pattern based on the plurality of cutting areas and the arrangement of cutting positions,
• wherein the plurality of areas includes a foot width direction part of the shoe last and a malleolus part of the shoe last,
• the foot width direction part includes a toe part of the shoe last, an instep part of the shoe last, and an ankle part of the shoe last, and
• the malleolus part of the shoe last includes a medial malleolus part of the shoe last and a lateral malleolus part of the shoe last.
