An experimental study on cutting temperature and burr in milling of ferritic stainless steel under MQL using nano graphene reinforced cutting fluid

Abstract

In this experimental study, cutting temperatures and burr forms were investigated during MQL (Minimum Quantity Lubrication) milling of AISI 430 ferritic stainless steel. In the experiments, uncoated and TiN (Titanium Nitride) coated WC (Tungsten Carbide) cutting tools were used and the experiments were performed under dry and MQL conditions. A commercial vegetable cutting fluid was chosen as cutting fluid and MQL flow rates were applied at 20 ml/h and 40 ml/h. Additionally, a nanofluid was prepared by adding nano graphene particles to the vegetable cutting fluid at 0,5%wt. Depending on the experimental results, low cutting temperature and small burr forms could have been obtained in the results of using TiN coated WC cutting tool and applying MQL method. In addition, the minimum cutting temperature and burr form were observed during MQL milling with nanofluid. Copyright © 2017 VBRI Press.
