| Abstract: | Some existing problems in design of gauge structure of rock bit are systematically analyzed. A new concept of the critical heel curve with special properties is proposed. A computer graghic method and corresponding computer programs with auto CAD softwares are developed, and a new handy audio visual accurate method for the design of rock bit gauge structure is presented. The result shows that the new method is simple, visual and accurate. |
