Machining-Control-Information Generation Device, Machining-Control-Information Generation Method, And Program

A machining-control-information generation method for generating machining control information for a machine tool to cut out a product by the machine tool from a workpiece, the machining-control-information generation method comprising the steps of:

• acquiring product information indicating a finished shape and finished dimensions of the product;
• acquiring workpiece information indicating a shape, dimensions, and a material of the workpiece;
• extracting a feature indicating a shape feature of the product based on the product information;
• specifying, from feature information indicating the feature, a machining method, using a machining-method specifying model for specifying the machining method of cutting corresponding to each piece of the feature information;
• specifying, from the feature information and partial machining method information indicating the specified machining method, an optimal feature, using a feature specifying model for specifying a feature optimal for machining the product;
• specifying, from optimal feature information indicating the optimal feature and the partial machining method information, a machining order when all of machining target portions corresponding to the optimal feature information are machined, using a machining-order specifying model for specifying the machining order when all of the machining target portions corresponding to the optimal feature information are machined;
• selecting, from among preset machining conditions including a type of a tool to be used and a machining path of the tool, a machining condition corresponding to the machining method and the optimal feature information based on the partial machining method information and the optimal feature information indicating the optimal feature;
• and
• generating the machining control information based on machining order information indicating the machining order, machining condition information indicating the machining condition, the optimal feature information, and the partial machining method information.

A non-transitory computer-readable recording medium storing a program, the program causing a computer to function as:

• a product-information acquirer that acquires product information indicating a finished shape and finished dimensions of a product;
• a workpiece-information acquirer that acquires workpiece information indicating a shape, dimensions, and a material of a workpiece;
• a feature extractor that extracts a feature indicating a shape feature of the product based on the product information;
• a machining-method specifier that specifies, from feature information indicating the feature, a machining method, using a machining-method specifying model for specifying the machining method of cutting corresponding to each piece of the feature information;
• a feature specifier that specifies, from the feature information and partial machining method information indicating the machining method specified by the machining-method specifier, an optimal feature, using a feature specifying model for specifying a feature optimal for machining the product;
• a machining-order specifier that specifies, from optimal feature information indicating the optimal feature and the partial machining method information, a machining order when all of machining target portions corresponding to the optimal feature information are machined, using a machining-order specifying model for specifying the machining order when all of the machining target portions corresponding to the optimal feature information are machined;
• and
• a machining-control-information generator that selects, from among preset machining conditions including a type of a tool to be used and a machining path of the tool, a machining condition corresponding to the machining method and the optimal feature information based on the partial machining method information and the optimal feature information indicating the optimal feature, and generates machining control information for a machine tool to cut out the product by the machine tool from the workpiece based on machining order information indicating the machining order, machining condition information indicating the machining condition, the optimal feature information, and the partial machining method information.
