Assemble inserts and cones respectively, and prepare for calculating 3d engaging distance of tri-conerockbit.
对牙轮和牙齿分别进行了装配，为三维啮合间隙计算做了充分准备。
2
The structure of tri-conerockbit is complicated. As the cutting structure touch the stratum directly, it affects the process of breaking rock and the performance of tri-conerockbit.
三牙轮钻头结构复杂，其中齿面结构直接与地层接触，对于岩石破碎过程和钻头工作性能的影响最大。
