Abstract:

The survival triplet today for any company is how to manage its product /service Cost, quality, and performance. The customers are continuously demanding high quality and better performance products/services and at the same time, they want the prices to fall. The shareholders are also demanding a required rate of return on their investment with the company. Thus, cost has become a residual. The challenge is being able to manufacture or provide service within the stipulated cost framework. Thus, cost management has to be an ongoing c ....etc

ABSTRACT

Cryogenic grinding permits heat-sensitive, thermoplastic, and elastic materials to be economically ground to very small particle sizes. The cryogenic process actually embrittle a material prior to size reduction and controls heat buildup in the grinding equipment. The result is high product quality and system productivity.
Cryogenic grinding involves cooling a material below its embitterment temperature with a cryogenic fluid, typically liquid nitrogen or, in certain applications, carbon dioxide. After cooling, the material ....etc

A cryogenic treatment is the process of treating workpieces at cryogenic temperatures (ie below -190 C) in order to eliminate residual stresses and improve the wear resistance of steels. In addition to seeking improved stress relief and stabilization or wear resistance, cryogenic treatment is also sought for its ability to improve corrosion resistance by precipitating micro-fine eta carbures, which can be measured before and after in one part using a quantimet.
The process has a wide range of applications from industrial tools to improving th ....etc

history of cryogenic grinding free pdf

Cold treatments or sub zero treatments have been around for quite some time. Machinery's Handbook describes the use of dry ice as far back as at least 1981 (the oldest version I checked). This article talks of using temperatures of -120F. There are stories of Swiss watchmakers burying newly made parts in snow, and it is well known that companies would age castings by putting them outside during the winter. Pierce-Arrow was one that was known to do this for their engine blocks. (Pierce had a definite ad ....etc

cost sheet and estimated cost sheet of amul company

The Birth of Amul

It all began when milk became a symbol of protest
Founded in 1946 to stop the exploitation by middlemen
Inspired by the freedom movement
The seeds of this unusual saga were sown more than 65 years back in Anand, a small town in the state of Gujarat in western India. The exploitative trade practices followed by the local trade cartel triggered off the cooperative movement. Angered by unfair and manipulative practices followed by the trade, the farmers of the district approac ....etc

CRYOGENIC GRINDING



INTRODUCTION
The science and technology of deep refrigeration processing occurring at temperatures lower than about 150 k. is the field of cryogenics. The name cryogenics is evolved from Greek word kryos meaning icy cold. Phenomena that occurs at cryogenic temperatures include liquefaction and solidification of ambient gases; loss of ductility and embrittlement of some structural materials such as carbon steel; increase in thermal conductivity to a maximum ....etc

A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel or oxidizer, that is, its fuel or oxidizer (or both) are gases liquefied and stored at very low temperatures. Notably, these engines were one of the main factors of NASA's success in reaching the Moon by the Saturn V rocket.

During World War II, when powerful rocket engines were first considered by the German, American and Soviet engineers independently, all discovered that rocket engines need high mass flow rate of both oxidizer and fuel to generate a sufficient t ....etc
