Introduction
Design and manufacturing are two essential aspects of engineering that are closely related. Design is the process of creating a plan or a blueprint for a product or a system that meets certain specifications and constraints. Manufacturing is the process of transforming raw materials into finished products or components using various machines and tools.
However, design and manufacturing are not independent activities that can be done in isolation. They need to be integrated in order to optimize all elements of the integrated manufacturing system. This means that the design should consider the capabilities and limitations of the manufacturing processes, and the manufacturing should be able to produce the design with high quality, efficiency, and flexibility.
Integrating design and manufacturing can bring many benefits, such as reducing cost, improving performance, enhancing reliability, increasing customer satisfaction, and enabling innovation. Therefore, it is important for engineers to have a systematic approach towards integrating design and manufacturing.
One book that can help you learn this approach is Fundamentals of Design and Manufacturing by G. K. Lal, N. Venkata Reddy, and Vijay Gupta. This book was published by Alpha Science International Ltd in 2005 as part of The Institution of Engineers (India) textbook series. It has 297 pages and 8 chapters that cover various topics related to design and manufacturing.
Engineering Design Process
The first chapter of the book introduces the engineering design process and its structure. It explains what engineering design is, what are its objectives, types, stages, methods, tools, and challenges. It also discusses how engineering design can be influenced by various factors such as customer needs, market trends, social issues, environmental concerns, ethical principles, legal regulations, etc.
The second chapter focuses on the identification and analysis of need, which is the first stage of the engineering design process. It describes how to define the problem statement, identify the customer requirements, analyze the existing solutions, establish the standards of performance and constraints, and formulate the product design specifications.
The third chapter deals with the origination of design concepts, which is the second stage of the engineering design process. It describes how to generate alternative solutions using various techniques such as morphological analysis, brainstorming, synectics, TRIZ, etc. It also explains how to evaluate and select the best concept using various criteria such as feasibility, functionality, aesthetics, ergonomics, safety, etc.
The fourth chapter covers the design decisions, which is the third stage of the engineering design process. It describes how to make decisions regarding various aspects of the design such as materials selection, shape optimization, dimensioning, tolerancing, surface finish, etc. It also explains how to use various tools such as decision matrices, Pugh charts, quality function deployment (QFD), failure mode and effect analysis (FMEA), etc. to support the decision making process.
The fifth chapter discusses the development of design, which is the fourth stage of the engineering design process. It describes how to refine and finalize the design concept using various methods such as prototyping, testing, simulation, modeling, etc. It also explains how to document and communicate the design using various formats such as drawings, reports, presentations, etc.
Manufacturing Processes
The sixth chapter introduces the manufacturing processes and their classification. It explains what manufacturing is, what are its objectives, types, stages, methods, tools, and challenges. It also discusses how manufacturing can be influenced by various factors such as product design, material properties, process parameters, quality standards, cost factors, etc.
The seventh chapter focuses on the machining processes which are one of the most common and important manufacturing processes. It describes how machining works, what are its advantages and disadvantages, and what are its main types such as turning, milling, drilling, grinding, etc. It also explains how to select and optimize the machining parameters such as cutting speed, feed rate, depth of cut, tool geometry, coolant type, etc.
The eighth chapter deals with the metal forming processes which are another group of widely used manufacturing processes. It describes how metal forming works, what are its advantages and disadvantages, and what are its main types such as forging, rolling, extrusion, drawing, sheet metal forming, etc. It also explains how to select and optimize the metal forming parameters such as temperature, pressure, strain rate, lubrication type, etc.
The ninth chapter covers the welding and allied processes which are essential for joining different parts or components together. It describes how welding works, what are its advantages and disadvantages, and what are its main types such as arc welding, gas welding, resistance welding, laser welding, etc. It also explains how to select and optimize the welding parameters such as current, voltage, arc length, gas flow rate, filler material, etc.
Design for Manufacturability and Integrated Manufacturing
The tenth chapter introduces the concept of design for manufacturability (DFM), which is the practice of designing products or systems that can be easily and efficiently manufactured. It explains what DFM is, what are its benefits, principles, guidelines, and methods. It also discusses how DFM can be applied to various aspects of product design such as geometry, tolerance, material, assembly, etc.
The eleventh chapter focuses on the concept of integrated manufacturing (IM), which is the practice of integrating all elements of the manufacturing system such as people, machines, materials, information, etc. using advanced technologies. It explains what IM is, what are its benefits, components, levels, and models. It also discusses how IM can be implemented using various tools and technologies such as computer-aided design (CAD), computer-aided manufacturing (CAM), computer-aided engineering (CAE), computer-integrated manufacturing (CIM), flexible manufacturing systems (FMS), robotics, artificial intelligence (AI), etc.
