Manufacturing
Manufacturing is the use of tools, machines and labor to produce goods for sale or use. It may refer to various human activities ranging from handicraft to high tech, but is most commonly applied to industrial production where raw materials are transformed into finished goods.

What hardness should SAE 1010 cold rolled steel be?
According to the ASME, SAE1010 {ASTM A179, ASME SA179} cold rolled steel (cold drawn) should have a Rockwell hardness of 60 RB. Hot rolled it is reduced to 55 RB.
*(Brinell hardness, 105; Knoop hardness, 123; or Vickers hardness, 108)
What was the first American textile mill site?
My source is www.woonsocket.org/woonhistslater.htm This article states that the first successful water-powered mill was built in Pawtucket, RI in 1793 by Samuel Slater. Submitted by Lois Robblee
Why is China a big manufacturing country?
China has the largest human population in the world. It has a huge amount of human capital. This means there is a HUGE labor supply. According to the laws of supply and demand, because the labor supply is so huge companies there can charge super super super low wages. This is because if 1,000 people say no to the low wages there are still thousands and thousands more that may potentially say yes and most likely one of them will. China is one of the cheapest sources of labor which is why many companies from other nations outsource to it.
What is QSN Manufacturing's revenue?
In 2001, QSN Manufacturing Inc. of Bensenville, Illinois, with $81 million in revenue and 200 employees
Why does hot rolled steel have mill scale?
Hot roll steel has a oxidised mil scale on the surface of the steel as it forms in the upper heat ranges from mixing with oxygen at a steel mill. Upon slow cooling, scale oxides will form a scale mainly of a type of iron oxide(s) usually of 3 distinct layers. This mil scale has a ability to be somewhat porous and can retain some moisture and is more noble in galvanic charges and at some times will potentially cause the underlying steel to corrode. The scale is not uniform in nature and can be loose in some areas and tighter in other areas and can pose a problem for people that want to paint or coat over it. The scale should be removed prior to any painting or TIG welding. Scale can be removed with various acid pickling type applications, flame treating, and mechanical blast or abrasion methods and then the freshly exposed cleaned surface of the reactive steel surface should be then protected from forming a fast acting blush rust.
When was the conciliation bill made?

represent a food manufacturing company in a way that they are proud to say that they have selective Food marketing services?
Are tires man made or natural resource?
Tires are a man made product made from natural resources.
Early tires used natural resources from rubber trees, cotton plants, and sulfur. The cotton was spun into fibers that were used embedded in uncured natural rubber to strengthen it and the tire was cured using the sulfur in a process called vulcanization.
Modern tires use natural resources from petroleum, iron ore, etc. The iron ore is made into steel which is made into steel fibers that are embedded in uncured synthetic rubber made from petroleum to strengthen it and the tire is cured.
5 What kind of additive and subtractive processes are used to manufacture actual physical objects?
An additive process is one that adds on material to an existing part or solid object to make it larger in mass. A subtractive process is one that shoves down material off of a part or solid object in order to make it smaller or lighter weight.
How is geometry used in manufacturing?
Normally, we learn Geometry on Mathematics. It is used to find the surface areas, volumes, etc. In the same way, geometry is used in manufacturing to be precise in the geometry i.e. size, area, length, shape, etc. The use of Geometry in manufacturing gives a right shape to the object and also a beautiful look to the structue/object.
What is the pantone color code for Ipod white?
There isn't a pantone for iPod white. The only white PMS colours available relate to textiles only.
What are the different types of descriptive research?
Case Studies
Job Analyses
Documentary Analysis
Developmental Studies
Correlational Studies
Examples of this are Surveys (questionnaires, Delphi method, interviews, normative)
Im only in psychology 1 but this is my most educated guess.=) hope this helped.=p
Why the epitaxial layer is now being used in silicon manufacturing process?
Epitaxy
Epitaxy is the process of growing a crystal of a particular orientation on top of another crystal such that both have the same structural orientation. The resulting structure is described as an epitaxial layer. In 1951 Gordon Teal and Howard Christensen at Bell Labs developed a process, now called epitaxial deposition, to grow a thin layer of material on a substrate that continues the underlying crystalline structure. Sheftal', Kokorish, and Krasilov described similar work on germanium and silicon in the U.S.S.R. in 1957. At the urging of Ian Ross, a Bell Labs team led by Henry Theurer used chemical-vapor deposition to add a thin epitaxial layer of silicon between the base and collector of a transistor in 1960. This approach raised the transistor's breakdown voltage while dramatically increasing its switching speed, (1961 Milestone) two important circuit-design characteristics. The added manufacturing cost of the extra process step was more than offset by improvements in device performance. The technology was quickly transferred to Western Electric and used in manufacturing silicon transistors for electronic telephone switching in the Bell System. Epitaxy

On a manufacturing drawing what does it mean to hold dimension?
Every dimension has a shown or implied tolerance, the dimensions shown as HOLD are the dimensions that are not to be affected by the stack up of tolerances of the holes or features around them.
this rifle depending on it's origanality and condition is worth between 400 and 800 dollars
