SUMMARY:

The employing the principle to drilling holes in metal is a more recent development. Friction drilling, also known as flow drilling or friction drilling, is an unconventional manufacturing process in which a tapered-tipped carbide rotating tool is pressed into a material, usually metallic. With the contact between tool and part, there is an increase in temperature, and consequently, a decrease in the resistance to deformation of the material due to its flow, thus causing the hole to be made. In this process, there is no chip formation, what occurs is the formation of a bushing due to the flow of the material. The bushing can be used, for example, as a fixing point by brazing or be threaded, serving as a connection point for screw fixings. With different possibilities of applications, the possibility of performing the drilling procedure by friction in different materials is also highlighted, among them, the material studied here is commercially pure titanium, known to be a promising material in applications in the naval and aeronautical industries, and for being considered one of the best biocompatible metallic materials. In this context, this work evaluates the geometric deformations caused in the height of the bushing and diameter of the hole formed in the process of drilling by friction. For that, the rotation speed and the feed were compared, both in dry and lubricated conditions.
