How do you start a career in six sigma?

Your question must be spawned from some sort of knowledge that it exists, so I assume you are already working with a company that has the methodology in place. Therefore I would start by speaking with the management or the company Black belt and show interest to what your desire is. Any company looking to improve their Quality will jump at the chance to work with you. Most companies will do the training with you and all Master Black belts are certified to do training. If your company does not do Six Sigma, take your skills to a job recruiter and ask them to find a company that uses your skills and applies the Six Sigma method to their process. This is the fastest growing part of any Industry right now, so finding an opportunity is not hard. Below are a few of the key factors to consider before obtaining training or becoming a Six-Sigma practitioner.

a. You should be a highly motivated process oriented resource with good communication and team building skills.

b. You should get involved because you want to help improve your company not because you are seeking credentials that promote your personal agenda. Job growth will come as a result but should not be the focus.

c. As a Green Belt you should have a minimum of 10 hours per week of disposable time to apply towards a process improvement project. Black Belts should be at least 20 hours per week (Full time is preferred).

d. Your company's leadership should be prepared to help select projects for you that have the highest business impact with the lowest risk of project failure. The leadership should also be available to help support the projects. This includes providing the necessary time for the team members to help drive the project as well as removing obstacles that may inhibit the team from being effective.

e. Another large component is the training / project mentoring aspect of the infrastructure. Do not search for the best training by focusing entirely on price. This is a complex methodology and requires a solid trainer to student transfer of knowledge. Many people settle for e-training because it is less expensive and more convenient. There are other low cost solutions that do not sacrifice training quality. In addition to the training make sure you have an available mentor that can help you manage all your newly acquired Six-Sigma knowledge.

There are other factors, however following the rules above you will be in good shape to get your company the improvements they are looking for.

Is a 1045 high carbon steel blade good?

1045 would not have that much of edge holding ability compared to other steels as it only contains .45% carbon meaning that its max hardness is much softer compared to steels such as 1080,1094,etc. It would be sufficient for disposable blades, but I wouldn't recommend depending on any other blade with that type of steel.

What is the difference between semi centrifugaal and centrifugal casting?

The basic difference is that rotation is a vital feature in centrifugal casting, if not emplyed, the casting won't be produced at all, whereas in SCC, we rotate the mould because -

1. Rotation of mould aids in the directional solidification of molten metal.

2. The centrifugal forces push the molten metal into complex parts of the cavity, and 3. The impurities easily get collected near the central core.

The mould would still be able to cast the molten metal, but rotating it only makes a better casting.

There are some other differences, like,

Core is used in SCC, it may/may not be used in CC.

SCC used for more complex shapes, while CC is used mostly used making hollow objects like pipes, tubes and bushes.

SCC uses a vertical axis, whereas tcc may use a horizontal or vertical or inclined axis.

Rotating speeds are lower in SCC compared to tcc.

What best jeans material are used in the clothing industry?

This is a very tricky question. When "jeans" were first invented, a variation on the work pants of the day, in 1873, the whole point was to make them extra durable. A combination of denim thread and seams reinforced with metal rivets provided exactly what the well dressed work person was looking for.

Today, the term has come to mean any trousers that are made in the style of the original work pant, but with many variations depending on the purpose. I have seen silk jeans, velvet jeans, and even sequined jeans.

As to the "best jeans material" you would have to specify what the purpose of the clothing in order to choose properly.

The new manmade fabrics are very useful because they can be made nearly indestructible by the using the proper weight of thread and weave, such as twill.

What is the relationship between economies of scale and a natural monopoly?

In those extreme cases where there are extensive economies of scale across the full range of potential output for market demand, it may be most economical for only one firm to supply the entire market. In this case one firm, rather than two or more firms, would have declining average costs across the entire range of market demand and be the lowest cost producer. The single firm would be characterized as a natural monopoly.

Is an hourly wage considered a fixed or variable cost?

In relation to total wage it is variable cost because as many hours you work as much you get but at other side wage rate with comparison to hour is fixed cost because it does not change from one hour to other hour.

For example: if somebody says that i will give you $10 per hour so now as many hour you will work you will get according to it.

But other side if somebody says that i will give you $10 per hour so whether you take an hour to complete a task or complete before that you will get $10 so in this sense you can say that it is fixed.

Who owned the largest manufacturing operation of the 1920s and what did he manufacture?

I would say there were 2 large manufacturers in the US during the 1920s.

  1. The US steel industry, mostly owned by US Steel. J. P. Morgan and attorney Elbert H. Gary founded U.S. Steel on March 2, 1901 (incorporated on February 25); they combined Andrew Carnegie'sCarnegie Steel Company with Gary's Federal Steel Company and William Henry "Judge" Moore's National Steel Company. US Steel became one of the largest monopolies in US History.
  2. Henry Ford founded Detroit Automobile Company. But it failed. The Henry Ford Company was the second company for Henry Ford, founded November, 1901. Henry Ford created new methods to mass produce automobiles. This meant ordinary people could afford to buy an auto; sales soared in the 1920s. But without STEEL, the Detroit auto industry would have been no more valuable than the river that flowed nearby. For many decades, Steel and Auto Manufacturing went hand in hand. Both industries helped the other grow, steadily, every year.
