INTRODUCTION English for Machinery Fabrication is a coursebook of English for Specific Purposes (ESP) designed to develop the English skills and basic knowledge in Machinery Fabrication for technical students who will work in the field after they have completed 120 hours of Basic English. This coursebook of English for Machinery Fabrication is one of the coursebooks for the subjects compiled in accordance with the curriculum approved by Vietnamese Directorate of Vocational Education and Training. The content of the book is not only short but also concise and easy for the learners to understand, knowledge and skills are integrated and logic is included. The most important aim of the coursebook is to help students develop the ability to deal with the concepts used in technical texts and the practical skills are acquired. The coursebook consists of eight Units which can be completed in 90 hours. The Units are organized around the various topics used in Machinery Fabrication field. The skills are introduced as they are related to the topic. Each Unit in the book is divided into different sections, as follows: 1. Introduction denotes a general information about the skills that students are required to gain. 2. Relevant knowledge provides the students with knowledge relevant to the skills they aim to achieve. 3. Objectives and Learning Outcomes shows what students will be able to do by the end of the lesson. 4. Order of Steps indicates the procedure the students should follow to achieve the skills. 5. Practice offers the students a number of tasks to practice so that they can acquire the new skills. 6. Consolidation and Testing: the student’s knowledge and skills can be enhanced with the Consolidation and Testing that is extremely accurate evaluation. The coursebook is designed by a teacher of English at Quy Nhon College of Engineering and Technology – Ms. Nguyen Thi Thanh Nga. She has Master’s Degree in the English language. She has a lot of experience in teaching English in general and English for Specific Purposes (ESP) in particular. She has experience in designing materials for different courses and participating in many foreign projects as a translator/ interpreter/ secretary. The helpful contributing ideas from the other English teachers are highly appreciated as well. We sincerely thank the teachers of Quy Nhon College of Engineering and Technology, especially the teachers of faculty of Mechanical Engineering who have been enthusiastic to help us fulfil the book. During the compilation, we have strived for making a complete coursebook, but certainly there are some unavoidable mistakes, so we hope to obtain the useful comments of teachers, students and readers.

In everyday life we use different strategies or approaches to read different texts. Sometimes we read quickly, skimming for general ideas or scanning for a specific point. Sometimes we read slowly, trying to gain a detailed understanding. How we read depends on the text – its length, its type – and our purpose in reading it. What is reading for specific information? When we are looking for a specific piece of information or specific words, this method of reading is called scanning. We ignore information that is not relevant to our purpose. Scanning is a useful strategy to use to find the section of a text about which a question is asked. This skill is often used when you have a specific question in mind. Scanning involves moving your eyes quickly across the page; you do not read every word, only the key words or ideas that will answer the question. In other words, you know what you are looking for and concentrate onfinding the answer. Scanning skill helps you learn to skip over unimportant words or information so that you can read faster. 1.2. Order of steps Step 1. Identify the information you need. Step 2. Move your eyes very quickly over the text and look for the answer to only one question at a time. Step 3. When you locate the information, read the surrounding text carefully to see if it is relevant Step 4. Re-read the question to determine if the answer you found is correct. Step 5. Write/choose the correct answer, and then move on to the next question and follow the same way. 1.3. Practice 1.3.1 Practice 1 Read the following passage about Fabrication Machines and Tools and answer the questions Hundreds of varieties of metal machine tools, ranging in size from small machines mounted on workbenches to huge production machines weighing several hundred tons, are used in modern industry. They retain the basic characteristics of their 19th- and early 20th-century ancestors and are still classed as one of the following: (1) turning machines (lathes and boring mills), (2) shapers and planers, (3) drilling machines, (4) milling machines, (5) grinding machines, (6) power saws, and (7) presses. 11
Turning machines The engine lathe, as the horizontal metal-turning machine is commonly called, is the most important of all the machine tools. It is usually considered the father of all other machine tools because many of its fundamental mechanical elements are incorporated into the design of other machine tools. The engine lathe is a basic machine tool that can be used for a variety of turning, facing, and drilling operations. It uses a single-point cutting tool for turning and boring. Turning operations involve cutting excess metal, in the form of chips, from the external diameter of a workpiece and include turning straight or tapered cylindrical shapes, grooves, shoulders, and screw threads and facing flat surfaces on the ends of cylindrical parts. Internal cylindrical operations include most of the common hole-machining operations, such as drilling, boring, reaming, counterboring, countersinking, and threading with a single-point tool or tap. Shapers and planers Shaping and planing operations involve the machining of flat surfaces, grooves, shoulders, T-slots, and angular surfaces with single-point tools. The largest shapers have a 36-inch cutting stroke and can machine parts up to 36 inches long. The cutting tool on the shaper oscillates, cutting on the forward stroke, with the workpiece feeding automatically toward the tool during each return stroke. Drilling machines Drilling machines, also called drill presses, cut holes in metal with a twist drill. They also use a variety of other cutting tools to perform the following basic hole-machining operations: (1) reaming, (2) boring, (3) counterboring, (4) countersinking, and (5) tapping internal threads with the use of a tapping attachment. Milling machines A milling machine cuts metal as the workpiece is fed against a rotating cutting tool called a milling cutter. Cutters of many shapes and sizes are available for a wide variety of milling operations. Milling machines cut flat surfaces, grooves, shoulders, inclined surfaces, dovetails, and T-slots. Various form-tooth cutters are used for cutting concave forms and convex grooves, for rounding corners, and for cutting gear teeth. Grinding machines remove small chips from metal parts that are brought into contact with a rotating abrasive wheel called a grinding wheel or an abrasive belt. Grinding is the most accurate of all of the basic machining processes. Modern grinding machines grind hard or soft parts to tolerances of plus or minus 0.0001 inch (0.0025 millimetre). Power saws Metal-cutting power saws are of three basic types: (1) power hacksaws, (2) band saws, and (3) circular disk saws. Vertical band saws are used for cutting shapes in metal plate, for internal and external contours, and for angular cuts. Presses This large class of machines includes equipment used for forming metal parts by applying the following processes: shearing, blanking, forming, drawing, bending, forging, coining, upsetting, flanging, squeezing, and hammering. All of these processes require presses with a movable ram that can be pressed against an anvil or base. The movable ram may be powered by gravity, mechanical linkages, or hydraulic or pneumatic systems. 12

A hammer is used to break things and hit nails. 2.2. Order of Steps Step 1: Write the sentence pattern: “Subject + is made of/ is made from + Material(s)” : determine Subject with the name of an object, and put the name(s) of material(s) after is made of/ is made from. Remember to choose is made of or is made from properly. Ex: A workbench is made of wood. A birthday cake is made from flour, sugar, eggs, milk and butter. Step 2 Describe the engineering materials and their applications. - Say the first sentence, the second one successively. Remember to replace the subject in the second sentence with the pronouns IT or THEY to avoid word repetition Ex: A hacksaw has a narrow blade in a frame. It is used for cutting metal.
