Über dieses Buch

During the past twenty years, developments in the manufacturing world have revolutionized many aspects of the production process. The introduction of computer technology and automation have had a particularly great impact on manufacturing with a variety of consequences. One consequence is that manufacturing issues cannot be addressed as isolated problems; they require "systems thinking." Thus study and understanding of the behavior of manufacturing systems is an emerging field with a strong interdisciplinary character and increasing importance from an academic and industrial point of view. The purpose of this book is to provide some fundamental methods and tools which can be useful in addressing design and operation issues in manufacturing systems. It is intended as an advanced undergraduate/graduate text for students taking courses in manufacturing and manufacturing systems. The problem solution manual and laboratory handouts are available from the author. In addition, this book can be used by academicians and practitioners. It can also be used by practicing manufacturing engineers to gain insight, techniques and methods related to practical issues of manufacturing systems.

1. Introduction

Abstract

The first chapter of this book attempts to provide a perspective of manufacturing issues, particularly from an economic point of view, and to establish a framework to aid decision making in manufacturing. For such a framework to be implemented in detail, two major challenges must be met: first, scientifically sound definitions of relevant manufacturing attributes must be settled upon. This will enable the trade-offs between attributes to be quantitatively assessed in the decision making process. The second challenge, which is directed in particular to the engineering community, is to develop technoeconomical models which allow the decision making process to be scientifically executed. Engineering science has made progress in terms of rigorously analyzing many engineering problems, but often these analyses are not performed in the context of relevant manufacturing attributes, and as such remain purely academic exercises which cannot be effectively utilized in industrial manufacturing practice.

2. Overview of Manufacturing Processes

Abstract

A manufacturing process is defined as the use of one or more physical mechanisms to transform a material’s shape and/or form. Manufacturing processes can be further divided into discrete parts processes and continuous processes. The metalworking industry, where many single items are produced, uses discrete parts manufacturing. Chemical processing, used in, for example, the film- or fiber-making industries, uses continuous processing. In this chapter, we will concentrate on discrete parts manufacturing.

3. Machine Tools and Manufacturing Equipment

Abstract

This chapter deals with manufacturing equipment, particularly machine tools. It follows the chapter on manufacturing processes because machines are basically the “embodiment” of processes, and it precedes the chapters on manufacturing systems because machine tools are the “building blocks” of manufacturing systems.

4. Process Planning

Abstract

When the design of a mechanical component is completed, it is usually documented in a drawing or a CAD file which specifies its geometric features, dimensions, tolerances, etc. In order for the design to be manufactured, a set of instructions are needed regarding the processes, equipment, and/or people to be involved in the manufacturing process. Such instructions are usually documented in an operation sheet or process plan (Fig. 4.1).

5. The Design of Manufacturing Systems

Abstract

The manufacture of products in the modern industrial world requires the combined and coordinated efforts of people, machinery, and equipment. Thus, a manufacturing system can be defined as a combination of humans, machinery and equipment that are bound by a common material and information flow. The materials input to a manufacturing system are raw materials and energy. Information is also input to a manufacturing system, in the form of customer demand for the system’s products. The outputs of a manufacturing system can likewise be divided into materials, such as finished goods and scrap, and information, such as measures of system performance.

6. The Operation of Manufacturing Systems

Abstract

The operation of a manufacturing system is the complex task of planning the material and information flows in the system. Proper material flow is what enables a manufacturing system to produce products on time and in sufficient quantity. It is a direct consequence of the system’s information flows: command information from human planners or from planning software presribes the material flow in the system, while sensory information about the status of the system’s resources is used to decide on the appropriate commands. The fundamental activity in the operation of a manufacturing system is thus determining the commands which prescribe the material flow in the system.
