PROCESSING CONDITION MANAGMENT SYSTEM, PROCESSING CONTROL DEVICE, PROCESSING SYSTEM, AND PROCESSING PROGRAM

A machining condition management system includes: a cutting tool that includes a cutting edge and a sensor; a storage that stores a mechanical machining condition for a machine tool and a measurement value, the machine tool performing machining using the cutting tool, the measurement value being measured by the sensor; and a processing unit that performs revision of the mechanical machining condition based on the mechanical machining condition and the measurement value stored in the storage. The processing unit determines a load on the cutting tool based on the measurement value in a first cutting process under the mechanical machining condition, calculates a revised value for revising the mechanical machining condition for at least one machining interval that has fulfilled a prescribed condition in the determination for the first cutting process, and updates the mechanical machining condition in a second cutting process, based on the calculated revised value, and outputs the mechanical machining condition in the second cutting process.
