MACHINING CONDITION MANAGEMENT SYSTEM, MACHINING CONTROL DEVICE, MACHINING SYSTEM, AND MACHINING 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 and a measurement value; and a processor that performs revision of the mechanical machining condition based on the mechanical machining condition and the measurement value stored in the storage. The processor 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.
