Titanium and its alloys, especially the Ti-6Al-4V alloy, are used on the manufacturing of dental implants and a deeper understanding of the micromachining of these materials is demanded. Burr formation is one of the parameters that can be used to study the machinability of a material and is a key factor on micromilling. Due to the small dimensions of the cutting geometry, deburring in micromachining is a difficult process. Hence minimizing burr formation is a major preoccupation in micromilling. Different authors found different scales when measuring burr formation. Therefore this work has the objective of presenting a comparison between two batches of experiments performed using different microtools and machine-tools and similar cutting parameters, and to find an optimal cutting speed regarding burr formation for one of the experimental setup. It was found that using a different experimental setup drastically changed burr formation results.
