In order to meet the diverse learning needs of overseas students, Xinxiang Vocational and Technical College has created three international digital course resources under the standards of numerical control technology. The course names are "CNC Milling Programming and Machining Technology", "CNC Lathe Machining Process Programming and Operation" and "Mechanical Drawing and Tolerance Fit". 

Through the study of these three courses, students can gain a solid understanding of the structure, basic working principles, operation methods, and procedures of CNC milling machines and CNC lathes, develop the ability to read and create mechanical drawings, lay a solid foundation for subsequent studies or work in the CNC technology industry, and create more possibilities for future career development.
