摘要
随着科学技术的发展和专业化程度的提高,很多企业的产品产量越来越大。采用手动切割、半自动切割的常用切割方式不能很好地满足其生产要求。
数控仿形切割机的出现不但可以切割出多种多样形状不同的工件,而且切割起来相当方便,同时也能解决某些工件的产量大的问题,另一方面由于其轻巧而且移动方便,特适合野外作业。如今,该切割机广泛的用于各种工厂企业。
机械设计的目的就是从社会的需求出发;创造性的设计出具有特定功能的新机械或者改进原有机械的性能,以此来满足人们在生活和生产之中的需要。
通过本毕业课题设计,掌握机械设计的一般方法,培养完善的设计思路,锻炼分析问题、解决问题的能力,特别是掌握总体设计和零部件设计的的方法与技巧。机械的综合运用和机械原理的目的就是让我们在日常的生产生活中合理的分析和解决问题,做到实践是检验真理的唯一标准。进一步巩固自己所学到的知识。

ABSTRACT
With the development of science and technology and to improve the degree of specialization, panies are increasing product yield. Manual cutting, cutting methods used semi-automatic cutting can not satisfy their production requirements.
CNC profile cutting machine appears not only can easily cut a variety of shapes of the workpiece, is more suitable for mass production, but also especially suitable for field work and for play, medium and small plants.
The purpose of the mechanical design is starting from the needs of munity; creative design of new machinery has a specific function or improve the mechanical properties of the original, in order to meet people's needs in life and production among.
Through this graduation design issues, the general method of mechanical design mastery, training perfect design ideas, exercise to analyze problems, problem-solving skills, especially methods and techniques to master the overall design ponents designed for. Integrated use of mechanical design and principles and other relevant expertise to analyze and solve problems in life and work, so that theory with practice, to further consolidate their acquired knowledge.
