Study of Macro and Micro Quality Determinants of Pieces Obtained from Optimized Drilling Process

The high necessity for productive quickness required nowadays, mainly due to globalization process, the research centers, industries and all social segments related to the development of productive activities are suffering a strong pressure to act drastically in order to avoid lost of time during products manufacturing. Among machining processes which have passed through this kind of requirement, the drilling process, subject of this research, has been suffering enormous changes in order to become better and optimized. These changes are the results of researches with the purpose of balancing the knowledge and the technological development concerned to drilling process in relation to other conventional machining processes with geometric defined edge cut. In such case, this issue aims a brief evaluation of macro and micro quality determinants (such as roughness and integrity of the inner surface) of parts obtained from optimized drilling process. It also aims to analyze which influences these determinants can have on the failure occurrence on the parts.
