Numerical control machining path planning method, and numerical control machining system and method

A numerical control machining system, comprising:

• a memory storing a plurality of programs and a plurality of sets of numerical control machining data and a processor;
• wherein each set of numerical control machining data is configured to indicate a size of a component needed to be machined, and the programs when executed by the processor, cause the processor to perform operations, comprising:
• acquiring numerical control machining data of the component from the memory, and generate a numerical control machining command according to the numerical control machining data;
• driving a lathe to execute a machining operation on the component in response to the numerical control machining command;
• determining whether currently-executed program section data and un-executed program section data among the numerical control machining data are interpolation section data, and generating a first result to obtain one program section data;
• and
• adding track data of an arc according to the first result and a second result whether a machining type described by currently-executed program section data is one of preset arc transitional types;
• generating a control command according to the added track data of the arc to drive the lathe to perform corresponding machining operation on a transition section.
