Abstract

The aim of this paper is to assess an experimental analysis of different tool-path strategies with respect to their influences on surface roughness and dimensional machining errors during free-form surface machining using experimental works. For this purpose, the machining of A17075-T651 material, which is used in the production of free-form surfaces for the die-sinking sector, in particular, was examined using a ball-end mill in a 3-axis CNC machine. The effects of the tool diameters and of the rough and finished machining strategies on the presence and character of form errors and surface roughness were investigated and the results were optimized using a Grey Relational Analysis.
