Five are workers. Others are managers.Dialogue（2）A: Tom, you said that / you like to / be a machinist, /didn’t youB: Yes, sir. /An outstanding machinist!A: Then, do you know /what you have to learnB: Sorry, sir. I am not clear about / it enough. Could you tell me /something about itA: You should pay attention to /manufacture and design. This book introduces /basic knowledge about manufacture. You will benefit from it.B: Thank you so much. I will try my best to learn it. Oh, this machine / looks interesting. What is itA: It is a very useful tool / in machining. The engine lathe.B: What does it use forA: The engine lathe / is a very useful tool in machining. It can be used for / drilling, reaming, threading, cutting tapers.B: I’ve got it.Dialogue（3）A: Sir, I am not familiar with / the equipment / in our workshop. Could you please / give me a handB: Sure. Any questionsA: Is this a benchB: Yes, it is.A: How about those toolsB: This is a vice, and that is a file. This is not a tool / but a workpiece. A workpiece / is the material / to be manufactured.A: Ok, I see. What’s that big machineB: It’s the engine lathe. And altogether we have five lathes. Here we have / five turners / to operate those lathes.A: I heard that /the engine lathe / is one kind of machine tools. Am I rightB: Yeap. The engine lathe, / milling machine, / grinding machine, /drilling machine, /shaper /and sawing machine/ are machine tools. All of them /are important /in mechanical engineering.A: Are there /any other machine tools/ in our workshopB: Of course. We have three milling machines, / two shapers/ and four drilling machines. A: That’s great. Thank you for your explanation.Dialogue（4）A: Tom, do you know / what the original machine isB: It may be tools, / which were used by / the primitive men.A: Right. The first tools that the mankind made were stone falchions, stone axes and stone hammers. All kinds of complicated and accurate modern machines are developed from the simple tools of the ancient times step by step.B: Oh, I see, sir. That is the reason why we learn the mechanical history.Dialogue Translation (5):A: Tom, Do you know what is milling methodB: Sorry sir. I have no idea about it.A: Milling is a process of generating machined surfaces. The process employs relative motion between a workpiece and a rotating cutter. After the milling process, some kinds of required surfaces can be produced.。
