A New Train of Thought for Defining Size of Making Pit From Steel Tooth

摘要: 在实验的基础上，首次完整地提出了平底钢齿圆柱形钢齿静压入岩石的造坑理论模型，并提出了坑形尺寸的计算公式。验证表明，计算的坑形尺寸与实际吻合，为牙轮钻头钻进过程仿真提供了理论依据。

Abstract: On the basis of a test, this paper first advances the theory about making pit on rock from steel tooth in the form of a flat bottom cylinder through static pressure, and obtains the formula for calculating pit size.Result shows that it is uniform with the fact
