The chapters of 21, 22, and 23 cover numerous things. Chapter 21 covers the following: defining numerical control, describing the difference between the incremental and absolute positioning methods, explaining how the numerical control (NC), the direct and/or distributed numerical control (DNC), and computer numerical control (CNC) systems operate and how computer-aid programming and manual programming is completed. Chapter 22 covers defining the term “industrial robot”, the term “automation”, describing several automated production systems (APS), and discussing the use of robotics in the APS. Chapter 23 covers the need for quality control, the difference between the two basic quality control techniques, how nondestructive testing works, and the methods for assuring quality control during and after machining.
In chapter 21, the material covered is numerical control, positioning methods, how the numerical control (NC), the direct and distributed numerical control (DNC), and the computer numerical control (CNC) works, and how computer and manual programming works. “Numerical control is not a machining process, but the operation of the machine tool by a series of coded instructions” (Walker, 2004, p. 399). The instructions from the NC have what is called alphanumeric data that is turned into electric current and then they can active the servo motors. They are connected to the machine’s feed and lead screws that provide the power for the cutter. The instructions tell the servos when to start, where they need to move, and how far they should move. The same program controls the feed rate, the cutter speed, the coolant flow, and sometimes even the tool changes.
The NC has turned into CNC and is both form of DNC. CNC is what is used ...

...st for defects in the part. Inspection by laser is another method, the laser detects tool wear and tries to compensate for it. This is an effort ot prevent the imperfections of parts of even happening. The eddy current inspection is based around the fact that resistance in the coils is caused by imperfections in the part. There are a few different eddy current tests that help with the inspection and completion of the part and maintaining the effort of quality control.
As presented, chapters 21, 22, and 23 give much information. Chapter 21 is the numerical controls and how the NC, DNC, and the CNC operate. Chapter 22 is about robots, and how they work in the industry. Chapter 23 is the importance of quality control, and different ways to achieve it.

The machine uses G codes just like C+ coding for computer programing but more of a linear approach. I had problems knowing if the machine was going to crash or not. Paying attention to the first line of codes to state whether or not if the tools are set right. The codes are given as a grid like X3.0 Y4.0 to know where exactly your machine is cutting in relation to the part. Sometimes I had to learn the hard way, machines crashing, and getting yelled at by my bosses. It is beneficial for me being able to take college courses that pertains to my

Materials engineering and computer engineering are two of the modern examples of industrial engineering. Industrial engineers have the challenge of incorporating today’s leading technological advances with the production of them in manufacturing facilities. Their purpose is to maximize output, while minimizing the costs for materials and production. This is why industrial engineers must have knowledge of product development, materials processing, optimization, queuing theory, production techniques, and engineering economy. Industrial engineers must have adequate skills in computer aided design and computer aided manufacturing.
One of the memories of my childhood I deeply cherish is that of my first visit to my father's small scale factory.Exploring the machinery which made my goal more easier and my dad sharing his experiences about the working of machines made me to grew up grossing my interest towards them. That was the time i chose to get into the field of mechanical.As a child, I was always intrigued by the working of complex mechanisms and equipment. I used to spend a lot of time trying to explore and figure out their principle. In school
Today the technological world has developed and has continued to innovate to provide an easier lifestyle. This is the main focus of automation. Automation has gained more recognition from people in the business and industrial sectors. The purpose of this report is to discuss and inform the overview knowledge in the automation field. “Automation is the system of manufacture designed to extend the capacity of machines to perform certain tasks formerly done by humans, and to control sequences of operations without human intervention” (Funk & Wagnalls New World Encyclopedia, 2017, p. 1). Humans are capable of such incredible things and have improved throughout time even develop automated technology to do those tasks. Automation and the technology
The first industrial robot, built in 1961, was a mechanical arm used to load presses. After the development of the computer and the CNC (Computer Numerical Control) in the 1970?s, the world saw great advances in the development of robotic control and the quality of robot manufacturing. As a result, there has been acceptance of the industrial robot world wide, improving the productivity and quality standards of industry (Hodges 3-5).

My first interest in Supply Chain Management resulted from my experience. Ever since I was young, I wanted to understand not just the ‘how’ of Mechanical engineering problems, but also why machines worked at the fundamental level. In particular, I was interested in learning the application of experimental techniques and principles governing Physics to solve problems. Therefore, I found the pursuit of B.E. in Mechanical Engineering almost a necessity, given my need to satiate my curiosity to gain deeper knowledge of that area.
Product designing, in this stage for continuous quality improvement the parameters of the design gets changed and the level of tolerance gets altered. This is very difficult for the manufacturing companies in implementation stage.
