In addition, the experiment system, whose target is product development, fuses the variety skills required by the process of product development. It increases the students' initiative spirit, and emphasizes students' dominant position. Students complete the structural design of products, parts processing inspection, control system selection and design, control system hardware development, control system software development and assembly debugging and other aspects of the final completion of the mini CNC lathe and development in groups, so that they can be trained as the actual production engineering. Graduate students can adapt to the new role quickly, and be equal to the new jobs.
III. APPLICATION AND EFFECT OF THE EXPERIMENTAL SYSTEM
A .Application of the Experimental System
The experimental system had applied to mechanical design manufacturing and its automation major for grade 2007 and 2008 since the experimental system was established. Students under guidance of teachers, completed the various stages from machine parts and components 254 mapping, design, processing to design and development of the numerical control system and the detection system to assembly and debugging. They successfully develop a mini CNC lathe and achieve basic functions of CNC lathe. Picture 4 shows the min CNC lathe
B. Effect of the Experimental System
Students of mechanical design manufacturing and its automation major are subject to the systems training of mechanical and electrical direction in the cultivation of this practice system. Their practical ability is improved and their sense of innovation is cultivated. Students in the 2007 and 2008 grade of mechanical design manufacturing and its automation major, who have systematically exercised by the practical system, achieve excellent results in various science and technology competitions. They won the first prize in the national university electronic design competition in 2011. They won the first prize in photoelectric group in the sixth national college students "free scale cup" intelligent car competition in 2011. They won the second prize in the fifth
national college students "free scale cup" intelligent car competition in 2010. They won the second prize in western camera group in the sixth national college students "freescale cup" intelligent car competition in 2011. They won the first prize of Chongqing pision in the 12th national college students "challenge cup" xtracurricular academic science and technology work competition. They won the second prize of Chongqing pision in the national electric mouse going through a maze competition in 2010, the first prize and second prize of Chongqing pision in the fourth national college students machine creative design competition in 2010.IV. CONCLUSION The experiment segment systematic not only breaks the shortcomings, which becomes a vassal of theoretical courses, of the traditional experimental links setting with course, but also the experimental system with the guide of typical product development can organically merge theoretical knowledge into the experimental links, exercise and cultivate students' practical ability and innovation ability. The experimental system on mechanical design manufacturing and its automation major in our university, around the mini CNC lathe, are constructed. It achieves good results. The experimental system with a goal of product development in large part urges the students' hands-on, exercise students' practical ability and cultivate students' innovation ability. While the students won honors several times in the municipal and national science and technology competitions.
机械设计制造及其自动化的实验系统的改革
Ⅰ.引言
实验教学是培养学生实践能力和创新意识的高等工程教育的重要环节。它是运用理论和练习学生综合运用知识能力的平台的桥梁。时间一长，工程大学重视理论教学，忽视实验教学。这导致了实验教学成为教学理论和工具来验证理论的附件，与大多数实验课程的实验证明，缺乏设计性、综合性实验。的内容，方法，手段的实验教学体系，实施素质教育，发展创新能力的系统不兼容。更为严重的是，在这种模式下，每个实验方面是相互分离的，它们不形成一个有机的整体，与学生的知识和创新能力缺乏宏观把握。实验系统不能满足经济和社会发展的客观要求。依托我在学校信息学科的优势，
