haviour of a Gomposite and
make the material behave softer that the usual case and
hence the resistance offered for drilling becomes lesser,
this will result in development of less Thrust. In com-
parison with TiO2 and ZnS filled composites, TiO2 filled
composites will offer more resistance that ZnS filled
composites. Since the ZnS filled composites are com-
paratively less brittle that TiO2 filled composites, they
behaves bit softer at early stages than TiO2 filled com-
posites, offering less oppositio n for drilling.
4. Conclusions
From the experime
made during testing, following conclusion can be drawn:
The thrust force generated during drilling of filled
composites mainly depends upon drill diameter and
the speed of drilling in the present case.
Effect of filler volume on the Thrust generated is
neglizable.
Thrust force developed during drilling of TiO2 filled
composites is more in comparison with ZnS filled
composites.
