TABLE OF CONTENTS With respect to surface integrity, describe the meaning of the following terms: abusive machining, gentle machining, low stress grinding, maximized machining, conventional machining (Section 1.7 and Figure 1.18).
In the early days of research into fatigue, it was conclded that there was a relationship between surface finish and fatigue strength. Explain the meaning of this in the context of machine surfaces and, using grinding as an example, show how this statement can be challenged (Section 1.2 and Figure 1.4).
The researchers, Field and Khales, were first to coin the term surface integrity . Explain the meaning of this term as well as the factors that influenced its adoption by industry (Sections 1.2 and 1.6 and Figures 1.8 and 1.9).
With respect to the surface integrity of machined surfaces, explain the meaning of the terms internal and external features (Section 1.3 and Figure 1.8).
There are a variety of reasons why surface integrity has only fairly recently received attention with respect to functional performance. Provide two reasons why this is so (Section 1.2).
Compare and contrast the surface integrity produced by electro-discharge machining (EDM) and turning (Section 1.3 and Figures, 1.9 and 1.10).
Using the example of a surface topography consisting of a series of semicircles (or indeed half sign waves), explain why the two topographies in their correct and inverted forms can have identical heights like Rt but very different surface integrities and functional performances (Section 1.2 and Figure 1.6).
Explain the difference between roughness, waviness and form. Use...
