数控铣床模型
摘 要
 数控铣床模型是用计算机及PLC软件控制铣刀进行铣削的机床,由于数控铣床的主要运动是铣刀的旋转运动,切削速度不是高,但是多刀连续切削,加上其自动化程度很高,所以它的生产效率非常高,铣床模型在教学中起到很到的演示作用,给同学们的学****也带来了很大的帮助。
中国的数控技术与国外相比起步比较晚,在技术和运用方面还有一定的差距,但近年来数控机床的运用得到的飞速的发展。数控机床已经开始逐步代替人工手动的机床,因为它具有后者不具备的卓越优点,例如它加工的工件精度提高了多倍,生产效率极高,特别是它可以完成许多非常复杂的东西,适用性很强!在当今高速发展的信息社会,计算机在其中扮演着重要的角色,而数控机床正是符合这一时代特点,将计算机技术和机床完美的结合在一起,广泛的运用到工业的每一个领域!
铣床模型的加工,要分析铣床的结构,设计好尺寸,确定好数据,画零件图和装配图,然后确定加工的装夹方案,设计合理的夹具;接着就是根据分析图纸所得的数据,以及装夹的方法,编写加工工艺路线及设定铣削参数与铣削用量;最后就是根据前面的分析,编写加工程序,进行零件加工。
关键词:教学作用,铣床加工,工艺分析
ABSTRACT
CNC milling machine model with computer and PLC is software control milling machine, milling of CNC milling machine mainly due to the rotation movement is milling, cutting speed is not high, but more continuous cutting knife, plus its high degree of automation in production efficiency, so it is very high, milling machine model in teaching demonstration role is to give students study, also brought a lot of help.

The numerical control technology abroad and in China than in the late start, technology and application of CNC machine, but in recent years, the use of rapid development. CNC machine has started gradually replaced manual machine, because it has the advantages of the latter does not have excellence, such as processing of workpiece precision improved more times, the production efficiency is high, especially it can do many things very complex, applicability. In today's rapid development of the information society, in which the computer plays an important role, nc machine tools is accord with the characteristics of a time machine, computer technology and perfect
