数控加工综合与创新实践项目分析与研究

Analysis of Comprehensive and Innovative Practice of Numerical Control Machining

实践教学在以培养高技能应用型人才为目标的高职教育中地位十分重要。近年来,对工程训练实践教学改革进行了探索研究,并获得了一定成效。其中的数控加工综合与创新实践项目在培养学生综合实践和创新能力方面作用突出,是正在研究完善的项目。对此项目的意义和实施情况进行了分析,并以实例进行阐述。该实例是学生自主设计的一个创意作品——"世博徽玺",并运用数控加工技术加工出来。详细介绍了零件的设计与加工方法,研究了其加工工艺和技术难点。通过该零件的设计与加工,学生主要运用了机械专业相关学科知识和跨学科的艺术美学知识,运用了三维设计建模、数控工艺与编程、数控加工技术等,很好地培养了学生的创新与综合实践能力,可为数控加工实践教学提供案例经验与借鉴。

Practice teaching plays a very important role in cultivating highly skilled and applied talents in higher vocational education. In the last few years, the practice teaching reform of the engineering training has been explored and has got some effects. The project of comprehensive and innovative practice of NC machining plays a prominent role in developing students＇ comprehensive practice capacity and innovative ability. This project is researched and improved. The significance and implementation of this project are discussed. Then, an example is introduced and analyzed. A creative works, which is called ＂2010 World Expo Emblem Seal＂, is designed and manufactured with CNC machining techniques by students. The design and processing method of the parts is described in detail. And the process and technical difficulty are studied. In this example, the students mainly used the mechanical professional knowledge and cross-disciplined art and aesthetic knowledge. They studied and applied the 3D modeling, CNC machining processes and programming, and machining technologies. This project greatly develops the students＇ creativity and comprehensive practical ability. It can provide some valuable experiences and references for NC practice teaching.
