Tool wear damage caused by abundant emulsion in milling operation of PH stainless steel

The use of cutting fluid in milling operations causes increase of temperature variation on the tool and may cause decrease of tool life. However, sometimes its use is necessary due to possible deleterious influence the temperature increase may have on the workpiece. Therefore, it is important to make fluid less harmful for the tool. In this work, two alternatives were tried: the application of emulsion internally to the tool, forcing it to get closer to the cutting edge and the use of an emulsion with higher concentration, trying to increase the lubrication and decrease the fluid cooling capac...
