This paper investigates experimentally the correlation between the cutting
fluid pressure distribution in the bottom clearance (the space enclosed by
the bottom of the hole being drilled from one side and the flanks of the dr
ill head from the other) and the flank wear of BTA drills. Two types of BTA
drills were studied representing two basic drill designs in the current us
e: single- and multi-edge drilling heads. Experiments included the study of
the bottom clearance topology, the measurements of the cutting fluid press
ure distribution in the bottom clearance; and the study of the tool wear to
pology. The results reveal the notable correlation between the cutting flui
d pressure distribution in the bottom clearance and the topography of tool
wear.
