Abstract
This is a complementary work of a study initiated using 1020 steel bars, published at the “Congresso Brasileiro de Engenharia de Fabricação – COBEF 2017”, under the title “Comparative analysis of the performance between conventional cutting fluids and chemically modified glycerin fluid in the turning of 1020 steels.” In this work, the performance of two bases made of chemically modified glycerin was evaluated and compared to different types of commercial cutting fluids (mineral, vegetable and semi-synthetic). The purpose of this work was to investigate the behavior of glycerin, after physical-chemical transformation, used as cutting fluid in turning operation. For this, the effect over the roughness of Aluminum bars was analyzed after turning operation using six different kind of fluids. These fluids were: water, commercial fluid 100% vegetable based, commercial fluid 100% mineral based, semi-synthetic, two fluids, non-commercial, made of glycerin chemically modified. Three different cut depths were used, ap=0.5 mm, ap=1.0 mm, ap=1.5 mm, machined length (l) of l=50 mm. The initial diameter (∅) of the steel bars was ∅=28.00 mm and the feed rate used f = 0.122 [m/min]. The turning operations were performed on a turning CNC, Romi brand, model Centur 30D. The roughness tests (Ra) were performed with a cut-off=0.80mm and length l = 4.00mm. The equipment used was a Taylor Hobson rugosimeter, model Suntronic s128 and the tests were performed inside the machining laboratory of the Pontifical Catholic University of Minas Gerais - PUC-MG. Results showed that the fluid made of glycerin chemically modified presented similar performance when compared to the commercial fluids, in some conditions the results were even better. This work indicated the possibility of formulating a cutting fluid with complementary additives using modified glycerin. Subsequently, complementary studies shall be carried out with this new fluid to evaluate the physic-chemical behavior of this new product in order to guarantee the quality of the product.
