Mechanical scribing test analysis of lateral ridges law on aluminum

In order to study the rule of lateral uplift of pure aluminum (purity is 99.999%) during mechanical scribing, based on the mechanical scribing test device, the tool tip angles are 80 °, 85 °, 90 °, 95 °, 100 ° The diamond cone cutter is used to perform mechanical scoring test on pure aluminum with a depth range of 5μm-25μm. Through the bump height detection analysis, lateral ridge height and groove depth - mathematical statistical relationship knife sharp corners, through the known parameters such as groove depth, groove on the bump height is pre-sentence, thereby pre-Groove play an important role in the control.
