ONCLUSIONS
The paper summarizes the effect and suppression of chatter in drilling and
micro machining operations. Research in the area of chatter recognition and
suppression has been conducted since the 1950s. There have been substantial
advances in the field of modelling and many of the theoretical conclusions
have been applied in practice especially in milling and turning operations.
Drilling is a process that has not been researched to the same extent and still
requires theoretical and experimental development. It has been seen that it is
necessary to incorporate axial-torsional, lateral, and bending vibrations into
one system as well as incorporating other influential parameters such as the
chisel edge, margin effect, pilot hole size, tool grinding errors, misalignment,
etc.
Micro drilling operations are yet to be addressed in the literature and
require a significant amount of attention in order to model the process
accurately and obtain explanations regarding the influential parameters. The
idea of applying theory that has been developed for macromachining
operations has shown to be inappropriate but the analysis, made on the
similarities and differences, does give important information. It is necessary in
future work to develop the mathematical models for micro drilling operations
and further work on the receptance coupling techniques for obtaining the
overall dynamic models of the tool-workpiece assembly.
