Effect of machining parameters, machining strategy, and curvature radius on the geometric quality of milled curved titanium surfaces

Abstract

The aim of this study is to determine the influence of cutting speed, feed per tooth, and machining strategy on the geometric quality of machined surfaces in surgical grade titanium Ti6Al4V. A 2^3 factorial design was performed to analyze surface roughness (Ra), dimensional accuracy, and shape tolerance. Results show that the machining strategy has a significant effect on surface roughness (Ra). Furthermore, convex surfaces exhibit better geometric tolerances than concave surfaces, and the curvature radius affects roughness parameters and dimensional accuracy.
