Abstract:
SAE 5160 steel has applicability in several industrial branches due to its good tensile and fatigue resistance, as well as having good tenacity, high hardenability and ductility. However, in the case of a steel that has carbon contents between 0.65 and 0.64%, it becomes very hard and abrasive, wearing out the tool very quickly. In addition, it has relatively low levels of chromium, manganese, silicon, and other elements, alone or in combination. This naturally results in a steel that is more difficult to machine than common carbon steels (1).
Machining is a complex process that requires a significant level of preparation and experimentation, as it involves numerous variables. Thus, it is almost impossible to accurately predict the behavior of metals when they are machined (2). It is of great importance to try to minimize this unpredictability as much as possible, which is mainly since it is a plastic deformation process where the restriction is given by the cutting tool and by the variety of options of input parameters in the process. Some of these input parameters are characteristics of the material to be machined, coolant, machine used to perform the machining, cutting tool, machining speed, feed rate and more (2).
The knowledge acquired through experimentation is beneficial for several reasons, including increased operational safety, cost reduction, assertiveness of results and reduced time spent on finishing.
Some research available in the literature (3-5) has indicated the need to study the cutting parameters as well as to evaluate the behavior of tool wear, to outline strategies to facilitate the machining process. Herein, for the first time, this study is carried out for SAE 5160 steel.
In this work, the cutting parameters influences in the turning of a SAE 5160 steel bar were analyzed, using two different cutting tools starting from the parameters indicated by the manufacturers and adapting them to the best machining conditions, aiming at greater use of the cutting tools, evaluating the results and impacts on operational risk as well as material properties. At the end, find a working range where the industry can perform rough machining in an economical, efficient and safe way.
