Abstract
A real-time drill monitoring algorithm is proposed, based on tool life and thrust models and real-time thrust measurements. The algorithm tracks the drilling process in two dimensions; drilling time and drilling thrust. A statistical approach was developed to consider the variation (both noise and signal) present in the thrust measurements. The algorithm developed is based on an extensive drilling experiment involving carbon steel and four independent variables; cutting speed ranging from 32 to 65 sfpm (162 to 330 mms-1), feed ranging from 00025 to 0015 ipr (00635 to 0-381 mm), drill diameter ranging from 0-2969 to 0-5781 inch (754 to 14-68 mm), and steel hardness ranging from 146 to 330BHN. A central composite designed experiment with 30 treatment combinations was used. The algorithm is demonstrated using data that were collected during the experiment.
