With the continuous development of China's national economy and the ongoing reform of its education system, there has been an increasing demand for skilled technical professionals. This has become a critical need for enterprises and a vital part of the country's development strategy. As a result, higher vocational education has become a key source of high-quality technical talent, providing strong support for building a reasonable educational structure, promoting economic transformation, and addressing employment challenges.
To meet the needs of employers, the teaching process must align with factory management practices and focus on the knowledge required by industry. However, traditional exam-oriented education struggles to engage students in vocational schools, who are naturally curious and motivated by hands-on learning. To address this, our school emphasizes stimulating student interest through the analysis and application of real-world processing techniques. This approach encourages students to think critically and apply various concepts, leading to excellent results in CNC machining, tool usage, programming, and machine tool operation.
The image above shows a project where students are learning macro programming, and their work is both engaging and impressive.
**Key Learning Points**:
1. Variable programming
2. Use of rotation commands
3. Removal of residual material
**Processing Techniques**:
1. Finishing surfaces using a ball-end mill
2. Using a flat-end mill to rough and finish residual material
**Processing Procedure**:
