Adjustment system for machining parameter and machining parameter adjustment method

An adjustment system for machining parameter, comprising:

• a storage device configured for storing a database, the database configured for storing a first machining data corresponding to a first cutting tool, wherein the first machining data comprises a type of the first cutting tool, a plurality of NC (Numerical control) program blocks, and a plurality of known capacity values of loss of each of the NC program blocks at a plurality of known RPMs (revolution per minute), respectively;
• a processor coupled to the storage device, wherein the processor comprises:
• a mapping module configured for determining a type of a tool under test, wherein 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 refers to the first machining data as a reference data of the tool under test;
• and
• a prediction module, wherein 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 is configured for predicting a predicted capacity loss value of the tool under test at a predetermined PRM while executing the machining program, according to the known capacity loss value of the at least one of the NC program blocks, to which the reference data is related, at the known RPMs.
