Abstract

The purpose of this scientific paper is to follow the influence of thermal galvanizing, as a technological process on the quality of the galvanized surface. The galvanizing technology used and studied involves at the end of the process, the removal of excess zinc from the surface by centrifugation. The zinc layer will be lower than that of simple immersion galvanizing. The measurements were performed following the roughness of the machined surface on a five-Section specimen – each Section being processed with a different cutting regime. The results were analyzed after each operation. The first measurements were made after the turning operation, followed by measurements made after pickling and fluxing and then after thermal galvanizing. Based on the results obtained, the aim was to set up a range of best roughness at which the galvanized part should have a commercial appearance and be made with a cost-effective cutting regime in terms of costs.

Abstract

This research presents an experimental study carried out for the modeling and optimization of some technological parameters for the machining of metallic materials. Certain controllable factors were analyzed such as cutting speed, depth of cut, and feed per tooth. A dedicated research methodology was used to obtain a model which subsequently led to a process optimization by performing a required number of experiments utilizing the Minitab software application. The methodology was followed, and the optimal value of the surface roughness was obtained by the milling process for an aluminum alloy type 7136-T76511. A SECO cutting tool was used, which is standard in aluminum machining by milling. Experiments led to defining a cutting regime that was optimal and which shows that the cutting speed has a significant influence on the quality of the machined surface and the depth of cut and feed per tooth has a relatively small impact on the chosen ranges of process parameters.
