The invention relates to a 3D (3-dimnesional) printing manufacturing method for a PDC (primary domain controller) drill bit body. The method has the technical scheme of comprising the following steps that a 3D model of the PDC drill bit body is built; the 3D model is subjected to 2D (...
Three equations constitute the mathematical model: torque, drilling rate, and bit life. The equations comprise cutter`s geometry, rock properties drilling parameters, and four empirical constants. The constants are used to match the model to a PDC drilling process. Also presented are qualitative and...

It is the key to ensure that PDC bit has choiceness of the work performance to reasonably place cutting.Presently common means of PDC bit placing cutting is to draw and adjust the scheme.But we have slow speed,poor efficiency to use the way and the designing work is also boring.What′s ...

Sorry about monopolizing your time a bit on Thursday. I'll have to try and be a more active participant on the VSTO forums. Rich 19. септембар 2005. Can you give us a little info on VSTO for Access 12? I know it must be pretty difficult to connect up with the exe...
Most works were completed by globally leading cutter and bit manufacturers, such as U.S. Synthetic and Schlumberger. Recently, it was found that the cutter's shape has a great influence on its impact resistance. PDC cutters with complex 3D shapes have been increasingly applied thanks to their ...
BI center bit is used for reaming hole bottom, the model No. likes 5 7/8"*7 1/2"*4 3/4" or just 5 7/8"*7 1/2" as the third diameter is not important. 5 7/8" is the passing through diameter, 7 1/2" is the reaming diameter, 4 3/4" is the diameter of front bit. ...
PDC钻头特征造型及参数化设计方法研究 马立安(机械设计及理论) 指导教师:**聪教授 摘要 PDC钻头结构复杂,形状变化多样,不规则,这给PDC钻头的设 计带来困难;每设计一种新钻头,都进行大量重复操作,严重影响效率。 需要研究三维环境下的PDC钻头设计,实现PDC钻头的计算机辅助设 计、优化和参数化设计。依据特征造型理论...
