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 us...

...fluorescent penetrant inspection, which is when the part is covered with a solution that when a developer is applied, shows the flaws under a black light. There is also spotcheck, which also uses a black light, but is coated in red liquid dye that when is whipped off it shows it is similar to the fluorescent penetrant inspection. There is also ultrasonic testing which is when sound waves are used to test 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.

- In chapter ten and eleven the book talked about formulating and testing hypotheses along with defining operationally. I found that when they talked about dissolving things in water and using different temperatures of water it was interesting because I never thought it mattered what the temperature of the water and the substance was going to devolve no mattered what. I also thought it was interesting that making butter can be used to show the process of formulate and hypotheses. I do think it is a good idea that children do this because they will learn how long it takes to make butter once the butter is finished.... [tags: Chapter Review]

- Industrial Robots and Manufacturing Automation Abstract Automation started out as an assembly line of workers doing the same repetitive task all day long. Some of the jobs were very boring, dirty, unpleasant, and possibly dangerous. After the introduction of the first robot in 1961, automation began to advance in ways people could only imagine. Each of the six basic styles of robot used in industry today were designed with different applications in mind. Some of the robots were designed for assembly, others are more suited for simple pick and place applications, while a select few are capable of carrying heavy loads over a large area....

- Black codes: These were state laws made in 1865 by the newly repatriated southern states by the local governments. These laws were designed to both deny blacks their new rights and to keep them second class citizens. The significance of these is that they denied rights to blacks that the constitution guarantees them. Sharecropping: This was a system of work devised by the southern farmers in about 1870. In this system of work often the newly freed blacks were still forced to work on farms for little to no pay, and instead be allowed to live there.... [tags: Chapter Review]

- Sharecropping was a compromise between the freedmen and ex-slave owners. This was taking place in the countryside of the South and allowed for the freedmen to rent land on a plantation from the ex-slave owners while working on that same land. Sharecropping came to be so because white landlords did not want to give freedmen their own land, believing that they would be lazy, but the freedmen did not want to go back to slavery. Its significance is that it gave blacks more freedom than when they were slaves, but they were still not independent, they still had to depend on white landlords.... [tags: Chapter Review]
