Based on this analysis, a new method for evaluating the bluntness magnitude of a Berkovich indenter was proposed. This method was examined by the experimental results of indention loading curves for pure nickel and aluminum alloy 8009, and good agreement was obtained. For thin metal films deposited on hard substrate, a method is established for determining the yield strength and hardening index of the film from nanoindentation loading curve.

Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.
