Abstract:
Base on the conventional twist drill, the new type of solid carbide twist drill which the length-to-diameter radio (L/D) is about 12 was developed with improved parameters of drill point and flute geometry. Study of intensity and rigidity of drill was performed by using analysis software ANSYS Workbench for the theoretical support and technical guidance for the design of twist drill. Tests were carried out to compare the new drills with the competitive drills in terms of tool life, chip breaking, and chip disposal. The results obtained from tests indicated that the new type twist drills have s

To overcome strong drilling force and over high temperature during orthopedic surgery, the four medical drills with different geometrical shapes by using superhard materials were designed. The bone drilling temperature field of superhard drill was theoretical analyzed. Results showed that brazed step drill has the most ideal drilling temperature. It controls the maximum bone temperature below 47°C even under dry drilling. The maximum bone temperature of brazed twist drill is a little higher than 47°C. With appropriate cooling method, brazed twist drill also could provide ideal effect. On the c

Accurate models of two-flute conical twist drills are needed for finite element simulations of the drilling process.

Due to the increasingly challenging thermal loads during drilling applications, coolant application is prevalent in twist-drill machining of metals.
