Abstract
The milling process is one of the most universal and known, with great variation in the type of machine used, movement of the part and types of tools. As frequent applications of the process are a obtaining of flat surfaces, slits, grooves, profiles, contours, cavities and threads, among others. The general advantages of the renovation process can be mentioned as high removal rates obtained and the possibility of obtaining surfaces of high quality and complexity. The objective of this work was to evaluate the effect of the application of canola based vegetable oil (Brassica napus L.), used as cutting fluid in the form of minimum amount of fluid (MQF) force and passive force) during the front milling process of the ABNT 1045 steel, a mild medium strength common steel used in structural and machine components, crankshafts, shafts, common gears and forgings. The work aims to apply mainly with a disclosure and use of ecologically correct cutting fluids that lead to a being used in the machining processes. A methodology based on the application of refined vegetable-based oil (canola), comparing the performance with the commercial oil application LB 2000 (also vegetable-based cutting fluid, indicated for ferrous metal plants produced by ITW Chemical Products Ltda.), both applied in the MQF form, with variation in the flow of fluids in 10, 50, 100 and 200 ml / also with a condition for the dry one. An experimental design (DOE) - factorial 2³, was performed, where as input variables at a shear rate (vc), the feedrate (fz) and shear depth (ap), with variation of the cutting fluid, while production variables were as shear forces (Fx), as shear forces (Fy) and passive forces (Fz). It has been found that the most influential components and force components are the feed and a depth of cut. Refined canola based vegetable oil presented in-line strength values with LB 2000 oil and lower than the dry condition. As flow rates considered to be more efficient for minors, the machining forces are 50 ml / h and 200 ml / h under the various conditions evaluated.
