Three Edged Drill vs. Double - Edged Drill in Aluminium Parts Drilling

Abstract:

This paper proposes an answer to a question like "it is better to use something new or use what we already know is a relatively recent technique novelty, which is found in tools manufacturer’s catalogues but still very rarely used, almost unknown in current industrial practice: spiral drill with three cutting edges. To give an endorsed answer, it starts machining a concrete case of a part of aluminium and research, based on a minimal experimental program, the processing with new drilling tool compared with the known helical drill. Answer the question initially is not simple, nor one given in few words and none with the high degree of generality, but one nuanced, depending on the performance indicators considered to be of interest and closeness of experimental working conditions than those found in current industrial environment. Helpful for the formulation and presenting the response is the processing of experimental data in the form of calculations, graphs and summary of the rejection’s causes. In this way, the concluding elements stand out more obvious and a number of partial answers can be formulated and justified recommendations can be done regarding: which of drills, where and in which conditions provides the best quality of machined hole, the best chip fragmentation and with the best ratio: price / quality / operation.
