Machining condition adjustment device and machining condition adjustment system

A machining condition adjustment device that adjusts a machining condition for a machine tool to machine a workpiece, the machining condition adjustment device comprising:

• a data acquisition unit that acquires at least one piece of data indicating a state of machining including a machining type in the machine tool;
• a priority condition storage unit that stores priority condition data in which the machining type in the machine tool is associated with a priority condition for the machining type;
• a preprocessing unit that produces data to be used for machine learning, based on the data acquired by the data acquisition unit and the priority condition corresponding to the machining type included in the data and stored in the priority condition storage unit;
• and
• a machine learning device that carries out processing of the machine learning related to at least either of a machining condition and a machining parameter for machining by the machine tool in an environment where the workpiece is machined by the machine tool, based on the data produced by the preprocessing unit, wherein
• the machine learning device includes
• a learning model storage unit that stores a plurality of learning models generated for each machining type in the machine tool, and
• a learning model selection unit that selects a learning model to be used for the processing of the machine learning from among the plurality of learning models stored in the learning model storage unit, based on the machine type included in the data produced by the preprocessing unit.
