Chapter 9 Modern Manufacturing Technology

abstract

In this chapter, the main concepts, and features of modern manufacturing technology, comprising engineering and

organizational technologies, are introduced. Moreover, the sub-

technologies of it, such as material handling technology,

production management technology etc. are discussed.

9.3 Production management technology 9.4 Summary

9.1 Introduction

Modern manufacturing technology is the result of the combination and merging of computer technology,Internet technology,numerical control technology,cybernetics(控制论）,system theory,robotics, manufacturing technology,and even management.With the development of this technology,modern manufacturing technology has progressed quickly,shown extreme potential and has a prosperous future.

9.1.1 Why Do We Need Modern Manufacturing Technology?

Increasing global competition has made many business leaders and policy makers turn their attention to such critical issues as

productivity and quality.Businesses seek new approaches to production

processes and manufacturing techniques and explore new boundaries of

technology.

9.1.2Areas of Modern Manufacturing

Modern manufacturing means much more than the basic fabrication technology.It involves market analysis,design,production planning,fabrication(including outsourcing),distribution and sales, customer service,and,finally,being agile enough to reconfigure the factory for the next product“six months down the road.”

The areas of modern manufacturing consist of the two subsections: engineering technologies and organizational technologies.

Engineering technologies are defined as the hardware and software of modern manufacturing systems.

Organizational technologies are defined as management and TQM（Total Quality Management) issues.

9.1.3 The Future

As mentioned above, manufacturing is much more than machining metals: manufacturing is an extended social enterprise. In the past，society has moved from an agrarian society(农耕社会）, to handcrafts in cottage industries, to operating machinery in factories, to computer automation/robotics, and finally to telemanufacturing by modem and Web.

9.2 Engineering Technology

9.2.1 Machining Automation Technology and Equipment

9.2.1.1 Numerical Control (NC) and NC Tools

Numerical Control(NC)

The two basic types of NC systems are:a point-to-point control system,which moves in a series of steps from one point to the next;a continuous path control system,which moves uniformly and evenly along the cutting path rather than through a series of horizontal and vertical steps.
