Abstract

The strong competition between companies has been forcing the optimization of production processes, reducing the reduction of manufacturing. Thus seeking the optimization of the machining process, as companies, the delivery time of product reduction ensuring its quality and cost reduction. Companies in the aerospace and molds and dies sector are characterized by products of high complexity and low demand. These are the only products, they are complex where their manufacture is possible in a machining center or five axes, as the requirements of the project characteristics are also increasingly high. Tests were performed, keeping the Tilt Angle at 25° and varying the Lead Angle at 0, -15, -60, 15 and 60 degrees. The material used in the experiments was AISI D6 in its state of supply, being machined with a spherical tip tool, in order to evaluate the influence of Lead Angle on the surface roughness. The main conclusion is the contact axis that varies only the tool and part design, Lead Angle, generated a strong influence on the surface quality of the part, especially when it comes to machining in five, with a variation only between the tests of up to 373%.
