The quantitative relationship between parameters of in-set diamond bits and their performance has always been the weak point in the research of drill bits.Quantitative analysis and rigorous theoretical calculation and derivation have shown the quantitative relationship between bit aging and life-time parameters. The conclusion is in good agreement with the qualitative results, which shows that it is feasible to study the quantitative relationship between the drill performance and the parameters. The quantitative relationship between the drill performance and the parameters can be used to guide the parameter design of the drill, and can be used to predict the drill bit Performance situation.
