It's an relief angle chart for boring bars vs dia of hole. Gives you
the primary and secondary angles for the sides of the cutting edge,
similar to a chart for endmill grinding.
The "Corrosion" is just the pixalation of the bitmap used to generate
the groundplane image for the rendering. It's not normally supposed to
be viewed that close :-) Mainly a time saving thing while raytracing
the scene. The bumpmap gets applied as a tile along the view plane but
is not part of the raytracing. Drawing took about 20min, choosing
colors and textures 10min and 1min to render. For more info on

Nasty corrosion on that diamond tread.

Say, what does the chart over the wheel of the grinder tell you?
