fineblanking:a high tech forming process that more closely resembles cold extrusion than stamping gives manufacturers new options for improved part quality,greater detail and the elimination of many secondary operations.It can form accurate parts that require only a minor secondary operation such as deburring in one press stoke.This eliminates most conventional operations such as casting,drilling,milling,broaching thereby reducing production time. Fineblanking produces high quality parts faster and can reduce production cost.(Exploring advanced manufacturing technologies,Stephen F. Krar,Arthur Gill)
corporate image:The corporate image comprises all the visual verbal and behavioral elements that make up the organization.If managed effectively it should protect the organization from competition.Therefore a fragile or a stable corporate image influences an organizations sales volume and will also affect the marketability and acceptibility of the company's products,services and human resources.(Corporate Communication,Identity,Image and Social Responsibility:BMW,Carina Bernt)
PID Controller:The basic concept behind PID control is to add another input to the system that input being the history of what actually happened when the control was applied.The difference between the actual value of whatever is being controlled and the set point is amplified.The derivative and the integral of the amplified difference are summed with the amplified error to produce the output signal.(Analog interfacing to embedded microprocessor systems,Stuart Ball,Stuart R. Ball)
Shaft Basis System:In shaft basis system the shaft is taken as a fixed member and the upper deviation on the shaft is zero.There are lower deviations int he dimensions of the shafts.By varying size of the hole various fits are obtained.There can be both upper and lower deviatiations
in the dimensions of holes.(Machine Design Jindal U.C.)
