Estudio de la influencia del avance y la velocidad de corte en la temperatura durante el torneado de acabado en seco del acero al AISI 1045: e309

Machining is an important manufacturing process due to its precision, high processing speed, and its applicability in a wide spectrum of materials. Nowadays, machining must fulfill the severe requirements of production, which include among others: increase of productivity, superficial quality, ecological and energy consumption standards, all to the smaller possible cost. In scientific literature, there are some investigations in turning of medium carbon content steel; however, there are no studies, which determine the most suitable cutting parameters, considering the cutting temperature and surface roughness. Therefore, this work aims to determine the most suitable cutting speed and feed rate, in dry finish turning of AISI 1045 steel with GC1125 coated carbide insert, from cutting temperature and surface roughness. For this, the scientific observation, experimental and measurement methods were used. The material of samples was characterized in terms of: chemical composition, heat treatment and hardness, as well as the machine tool and the cutting tool used. In addition, the setup and experimental design are shown. The temperature of cutting area was measured using an infrared thermometer, while a standard sample was used to determine the surface roughness. Statistical analysis was performed and, the models of multiple linear regression were determined, from which the graphs of contour and response surface were made, which allowed determining the feed rate and cutting speed for the given processing conditions.
