| Summary: | Actuator assisted machining operations are one of the highly researched pioneering
areas in manufacturing as they offer a tolerance control close to 0.010um and find
wide applications in precision machining and special machine industries [14] .The
costs of these special machines are not justifiable in some machining applications,
requiring local tolerance control. Backlash and positioning errors makes it difficult
to achieve close tolerance in CNC machines. Actuator assisted cutting tools provide
excellent solution to these problems by isolating the depth of cut from CNC using
externally controlled actuators.
This project aims at eliminating the backlash error in CNC machines, particularly in
boring process by developing a piezoelectric actuated rotary boring tool to perform
precision machining on AI 6061 in a conventional CNC milling center by
controlling the depth of cut through externally controlled piezoelectric actuator. The
designed boring tool increased the ability of cutting complex profiles in boring
using piezoelectric actuated cutting tool. The roughness of the profiles machined
varied between 0.151 um to 0.194 um and is in agreement with the literatures. |
