The Effect of EP/AW Additives in Emulsion Mist on the Geometric Structure of the Machined Surface during Carbon Steel C45 Turning

Article Preview

Abstract:

One of the problems of metal alloys machining in view of the environment protection is the use of cooling lubricants. From this viewpoint, it is preferred to limit the use or completely eliminate them from the cutting process. The solution may be the method of Minimum Quantity Cooling Lubrication (MQCL). The results of the machined surface roughness measurements of carbon steel C45 after turning when: machining for dry cutting, using cooling method MQCL and using MQCL with additives EP/AW have been presented. One used two anti-wear and antiseizure additives based on phosphate ester. Experimental studies have been planned according to the Parameter Space Investigation method. The application of EP/AW additives entered in the emulsion determined the ranges of cutting parameters at which lower values of selected roughness parameters were obtained in comparison with dry cutting. The lowest values of Ra and Rz parameter for variables of cutting parameters and creating emulsion mist within their whole range were obtained for cooling with pure emulsion mist based on boric acid and amine compound.
