小径ボールエンドミルによる切削痕が機能性に及ぼす影響

抄録

In the manufacturing field, adding value and reducing environmental impact are required. This study aims to develop cutting technology for creating highly functional surfaces while machining a desired shape to consolidate and reduce the surface treatment process, which emits a significant environmental burden. Specifically, we make a surface with an intended uneven shape by cutting marks, improving its functionality.

In this study, we created surfaces with square cutting marks of three different sizes by ball end mills with 10 mm, 5 mm, and 2 mm diameters. To evaluate the functionality of those machined surfaces, the gloss and the static contact angle of water were measured. The gloss level varied with the size of the cutting marks, although there was no proportional relationship between the size and the gloss level. Observation of the static contact angle of water from the tool feed direction showed that the contact angle increased with smaller cutting marks.
