Various methods exist for determining the qualitative and quantatiye integrity of a diamond-turned surface. Particularly, the micro-roughness and residual stress of surfaces are used for preliminary evaluation of surface integrity. That is to say, the availability of reflectors, capacity of disc-memory and other capabilities of diamond-turned surfaces are dependent on the surface integrity. The amount of micro-roughness and residual stress depend on the conditions of the machining process, in this case, on the single crystal diamond turning conditions. Especially, the residual stress are affected by the manufacturing (heat treatment and each machinig) of Al alloys. From these points, the paper describes the phenomena of micro-roughness and residual stress of the surface region caused by various machining coditions.
