Evaluating the hole quality produced by vibratory drilling: additive manufactured PLA+

Improving the surface quality of additive manufactured parts like poly lactic acid (+) is an important study that currently being carried out by researchers. To reach high-quality, different conventional and nonconventional methods are applied. In this study, capability ultrasonic vibration in drilling (+)was examined. The process was implemented two methods: vibratory drilling. Then, thrust force chip type were analyzed, effect them on roughness, delamination, circularity, cylindricality have been investigated. As a result, it indicated lower broken chips, which generated drilling, caused parameters to be improved compared method.
