Resumo
In this work, the performance of a mineral and a vegetable-based cutting fluid during drilling operations in an AISI 304 austenitic stainless steel (ASS) is compared. The tests were made on ASS plates using a milling machine and HSS drills until the catastrophic failure of the drills. The wear of cutting edges was monitored periodically by observations in a stereomicroscope (SM). In addition, measurements of noise, temperature and current were taken. The results showed that tools lubricated with vegetable fluid had lower wear level than tools lubricated with mineral based oil. Power consumption remained without changes when the cutting fluid was changed while lubrication with the vegetable fluid reduced the noise level of the operation. These results are promising considering the machining performance and lower environmental impact that can be obtained with a vegetable-based cutting fluid.
