最新中职数控技术应用专业实用英语授课教案:说明

《数控技术应用专业实用英语》授课教案(Teaching plan)说明《数控技术应用专业实用英语》是的一本中职数控专业英语教材,简单实用,特别适合中等职业学校学生学习。
为学生在校学习期间最后一个学期的英语教材。
本教材应当在学生结束基础英语的学习之后讲授。
而且学生必须在学习了相关的专业知识以后学习这本教材,因为学习本教材的目的是学习专业英语,而不是期望学生通过学习这本教材获得新的专业知识。
本教材应当由英语教师教授,但也可以由英语基础好的专业教师教授。
英语教师在教授本教材之前,应当对计算机辅助制图、数控车床编程、可编程控制器、单片机等有一定的了解,但是不必了解得很细,不要害怕在讲解专业知识或专业用词时犯错误。
实践证明,学生,包括英语基础差但专业学习不很差的学生,会主动地帮助英语教师解决专业方面的问题;满足学生,特别是满足英语基础比较差的学生的表现欲望,正是激励学生学习的好机会。
专业教师授课时应当注意多说英语,注意发音,注意难句子的讲解与分析,注意英语与专业的紧密结合,不要把本教材当成数控知识的专业课本。
电子教案主要是为英语教师教授本教材编写的,也可供教授本教材的专业教师使用。
此电子教案共有5个文件夹,每个文件夹为一个单元(Unit);各个文件夹中每一课(Lesson)是一个word文档;文档名称里的U代表Unit, L代表Lesson,如,word文档“U2,L1”,则表示第二单元第一课。
此教案仅供参考,在实际教学中,各位教师要根据不同的学生,灵活处理。
比如,有的课文对英语基础和专业基础都比较好的学生可以用一小课时(45分钟)完成,而对英语基础和专业基础都比较差的学生可以用一大课时(90分钟)完成。
电子教案指出了课文中的错误,并提出了正确修正方案。
如,第1单元第2课(U1,L2)在Step III Text 中有“3)Fig. 1-2-1中的单词Tool Columm应改为Tool Column. ”同时,对课文或对话中出现的欠妥之处也作了说明。

They can be played back,edited,and processed by the controller.All programs resided in RAM,however, are lost when the CNC machine is turned off.These programs can be saved on auxiliary storage devices such as punched tape,magnetic tape,or magnetic disk. The MCU units have graphics screens that can display not only the CNC program but also the cutter paths generated and any errors in the program.
NC technology has found many applications, including lathes, and turning centers, milling machines and machining centers, punches, electrical discharge machines (EDM), flame cutters, grinders, and testing and inspection equipments. The most complex CNC machine tools are the turning center with a ten-station turret that accepts quick-change tools, the vertical machining center that the tool magazine is on the left of the machine and horizontal machining center equipped with an automatic tool changer, shown in Figure 1-1 and Figure 1-2 respectively. Generally speaking, tool magazines can store 200 cutting tools.
