Análise da qualidade superficial no fresamento em raio com ferramenta de ponta esférica

Abstract

The primary purpose of this project is to benefit the industry in the manufacture of components with complex geometries, in order to obtain reduction in the finishing of the machining processes. It is presented the process of milling complex shapes with solid spherical tip tools. The machined surface is compared taking into account the influence of the use of the effective diameter for the calculation of cutting parameters in milling with a spherical tip cutter in the longitudinal and transverse direction. In the comparison, work piece with cross-cut machining had improvements in the roughness results for half the evaluated points. It should be noted that the cutting parameters were increased in these situations. Also, a reduction in process time and reduction of wear of the cutting tool was identified.
