Abstract:  
The quality of a machined surface is becoming more and more important to satisfy the increasing demands of sophisticated hardware performance, longevity, and reliability. Aerospace structures are being subjected to more severe conditions of stress, temperature and hostile enviorments. Section size is being reduced in response to the goal of reduced weight wo that the surface condition of a component has an increasing influence on its performance. In response to the above needs, there has been a continued development and use of heat resistant, corrosion resistant and high strength alloys in a wide variety of structural applications. These alloys include high strength steels heat treated to strenght levels up to 300,000psi, stainless steels, titanium alloys and nickel and cobalt base high temperature alloys.
