A machining-control-information generation device includes a feature extractor that extracts a feature indicating a shape feature of a product based on product information, a machining-method specifier that specifies a machining method, using a machining-method specifying model, a feature specifier that specifies an optimal feature, using a feature specifying model, a machining-order specifier that specifies a machining order when all of machining target portions corresponding to optimal feature information are machined, using a machining-order specifying model, and a machining-control-information generator that selects a machining condition corresponding to the optimal feature information indicating the specified machining method and the specified optimal feature, and generates machining control information based on machining order information, machining condition information, the optimal feature information, and partial machining method information.

A cutting apparatus including a cutting unit on which a cutting blade is detachably mounted, a control unit for controlling the cutting unit, and a blade case holder for holding a blade case for storing the cutting blade is provided. The blade case is provided with an IC tag allowing reading and writing of use history information of the cutting blade. The control unit is connected to a read/write unit for reading the use history information from the IC tag of the blade case held by the blade case holder and writing the use history information to the IC tag. The use history information read from the IC tag by the read/write unit is reflected in processing conditions for a workpiece to be processed, and the use history information after processing of the workpiece is written to the IC tag by the read/write unit.
