【Abstract】 Five kinds of methods widely used in selecting PDC bits are analyzed comprehensively, and four formulas for the economic evaluation of PDC bits are introduced A software is developed for analyzing the selection of PDC bits. A uniform expression is used to implement the software for convenient programming By means of an object oriented programming,the methods for selection of PDC bits can be built into a software under Windows 95 by using Visual Basic 5 0更多还原
