- Abstract
The aim of this study is to determine the influence of the cutting speed, feed per tooth and machining strategy; on geometric quality of the machined surface, in the ball milling tool of the surgical grade titanium Ti6Al4V (In this paper, geometrical quality, is considered; parameters of surface roughness, dimensional accuracy and shape tolerance). The samples were machined by means of ball milling tool. Analysis of the influence of the factors was performed by means of a 2³ factorial experimental design. Further, an ANOVA (analysis of variance) was performed between concave and convex spherical geometries of the same radius, to determine the influence on the machined surface geometric quality geometric quality of the machined surface. Additionally, an ANOVA was performed; between convex spherical geometries different radius to determine the influence on the geometric quality of the machined surface. The factorial experimental design results showed that machining strategy factor on surface roughness parameters Ra. Furthermore, On the other hand, the ANOVA for the concave and convex spherical surfaces shows that the change from concave to convex surface influences geometric tolerance. Finally, ANOVA for convex spherical geometries shows that the radius changes influences surface roughness Ra, Rq and Rz, geometric tolerance and the dimensional accuracy.
