  • Publication number: 20180157241
    Abstract: A adjustment system for machining parameter includes a storage device and a processor. The processor includes a mapping module and a prediction module. The mapping module determines a type of a tool under test. When the type of the tool under test is determined as the same as the type of the first cutting tool, the mapping module obtains the first machining data from the database and as it as a reference data of the tool under test. When a machining program related to at least one of the NC program blocks is going to be executed for the tool under test, the prediction module predicts a predicted capacity loss value of the tool under test at a predetermined PRM while executing the machining program.
