RESUMO
The preciptation hardenable stainsless steel presents high mechanical strength and corrosion resistance, having a wide application field, specially in the aerospace industry. The present work evaluated the influence of cutting fluids in the 15-5PH stainless steel milling, using carbide tools, TiAIN coated. Experiments were carried out for roughing and finishing operations, varying the carbide tool c1ass (M20-M40 and M30-M40), the cutting speed (100 and 120 m/min for finishing operation and 120 and 140 m/min for roughing operation), the lubri-cooling conditions (without cutting fluid, internal and external emulsion application) and the emulsion concentration (7% and 12%). Finally, additional experiments were carried out, for comparison effects, with neat oil application with minimum quantity of fluid (35 ml/h) and also with low flow rate (250 ml/min). Tool wear, tool life, power consumption and workpiece roughness were measured. The analysis of the results allowed to conc1ude that the machining without cutting fluid gave longer tool life than with emulsion application, both in roughing and finishing conditions. The minimum quantity of fluid utilization led to a longer tool life than the dry condition. The use of neat oil led to a decrease of the power consumption, even with the minimum amount contained in the MQF technique. But the main contribution of this work is that the experiments with application of neat oil with low flow rate presented longer tool life than the other lubrication/refrigeration conditions experimented, showing that lubrication effect occurred when neat oil was used, with consequent reduction of power consumption
