In recent years, although a large number of CNC technology applied talents have been cultivated, there is still a shortage of CNC technology talents. This has prompted us to think about how the CNC technology talents trained by the education department can meet the needs of enterprises, and what type of CNC technology talents are urgently needed by enterprises? What are the requirements for knowledge structure and ability structure? This highlights that teachers strive to closely integrate what students learn with what they use in their daily teaching, and strive to explore new teaching methods and processes.

1、 Emphasize practical skills in teaching implementation

Vocational education bears the responsibility of cultivating talents in various aspects such as production, service, management, and construction, continuously delivering high-quality technical talents to society and enterprises. The traditional curriculum system emphasizes a subject based system, emphasizing the imparting of unilateral knowledge and abilities to students, thereby ignoring other abilities of students, resulting in a lack of awareness of curriculum integration. The emphasis on the systematic and extensive nature of a single subject can no longer meet the changing social needs of the present.

Based on the multi-dimensional considerations of society and enterprises for talents, as well as the demand for high-quality talents in the overall education background, we need to pay more attention to the combination of disciplines, cultivate students' ability to think and handle problems from multiple dimensions and perspectives, which is in line with the development requirements of higher vocational education. Improve the integration of CNC teaching with CNC professional teaching to seek greater development opportunities for students.

2、 Optimize professional training subjects and improve students' hands-on skills

Encourage students to increase their interest in CNC machining by watching a series of optical discs, such as the Mechanical Borrowing Work Education series, to visit CNC lathes, CNC milling, CNC wire cutting and other equipment and on-site production methods in unloading and processing enterprises. This will help them gain a certain understanding of CNC machining, and then enable them to master the principles through theoretical teaching.

In practical training courses, students are required to correctly apply the theoretical knowledge learned in the classroom. In practical training, they are required to understand the drawings and develop processing techniques according to the requirements of the drawings. The most interesting aspect for students in CNC classes is programming, and there are many programming instructions for CNC machine tools, and different models of machine tools also have different programming instructions. At the same time, it also involves examples in mathematics, technology, and other aspects. Therefore, programming complex parts is a difficult point in CNC teaching. In the teaching process, complex part machining is decomposed, and some simple machining examples are practiced first, following the principle of from few to many and from simple to complex. From rough machining to precision machining, and introducing loop instructions, students can gradually master the writing of complex parts, which can improve their learning of practical training projects.

Vocational education is an important type of education development in China. With a developmental and comprehensive perspective, it aims to see the future development of students, integrate with social enterprises, and shoulder the important mission of meeting social needs and cultivating applied and skilled specialized talents in production, construction, and service. It plays an important role in China's economic construction and development. As an important public basic course in vocational schools, the construction and reform of mathematics courses are of great significance for improving the comprehensive quality of students. Therefore, it is necessary to further explore the reform of the content and methods of mathematics in vocational schools to adapt to the needs of the development of Rixin County.
