Application of the Bottom Hole Path CAD to the Rock Bit Insert Arrangement Design

The CAD system for rock bits used in geological exploration is a soft system redeveloped with the visual language—Visual LISP on the Auto CAD platform based on fairly good hardware environment. Begun with the analysis of the rock bit movement in bottom hole, the movement imitation calculation is carried out for the rock bit with a view to the design features of the rock bit used in geological exploration. Hence produce the breaking diagram in bottom hole to direct the insert arrangement design.
