摘要在目前市场使用的板材切割机大多分为两种：1、工人手工切割；2、机械切割固定长度板。第一种方案过度依靠人力资源，人力成本投入过大，效率低下，产品质量不能保证；第二种方案切割效率较高，但是会出现不能完全切割的情况出现，切割板材长度是固定的，缺乏切割的灵活性，功能性单一。我的设计任务是在原有切割记得基础上做出改善提高，解决不完全切割的问题，使原有板材切割机能切割不同长度的板材，进一步提高切割速度，减少人力成本的投入，提高生产效率，保证产品质量，以实现生产自动化。52570

SolidWorks软件作为　一种使用工具，能够帮助设计人员从繁琐的绘图和计算中解脱出来，提高设计人员的设计效率和绘图质量，从而能够集中精力去进行方案的设计工作，而其中许多高级功能和丰富的插件，确保了设计的精确性，克服了产品限制条件苛刻、设计周期短、总体参数变动较大、继承性少及技术储备不足等诸多困难。

Abstract I need to design a high-speed CNC cutting machine is used for cutting sheet metal magnesium. Currently on the market by the use of sheet metal cutting machines are cutting fixed-length glass magnesium board, there is no arbitrary length can be cut speed CNC cutting machine, cutting machine is currently a lack of flexibility, and the emergence of the problem can not be completely cut. My task is designed on the basis of the original cutter improved, improve cutting speed and improve the problems can not be completely cut, so that it can cut any length of the plate, improve production efficiency and reduce labor costs of inputs, automated production, ensure product quality.

SolidWorks software as a tool that can help designers from the tedious freed drawings and calculations to improve the efficiency of the designer's design and drawing quality, and thus be able to concentrate on the design of programs, many of which advanced features and rich plug-in, designed to ensure the accuracy of product limitations to overcome harsh conditions, the design cycle is short, large changes in population parameters, inheritance less and lack of technical reserves and many other difficulties.

Keywords: CNC high-speed sheet cutting machine; modeling; SolidWorks
