Quality improvement of deep-hole drilling process of AISI D2

摘要

Deep-hole drilling is a relatively complex drilling production process due to the high-hole diameter to length ratio which makes the tool shaft prone to vibration and results typically in low-quality holes from geometry and surface finish viewpoints. This study is aimed at investigating deep-hole drilling process for AISI D2 material taking into account different process input parameters. The hole quality is studied and improved using a response surface-based design of an experiment technique which resulted in a better hole quality.
