THE INFLUENCE OF COOLANT TYPES ON SURFACE ROUGHNESS IN THE TURNING PROCESS

Abstract

To lessen the friction that forms between the tool and the workpiece during the turning process, a variety of coolants are utilized. Each coolant type has benefits and drawbacks. The kind of coolant used directly affects how smooth or rough the surface of workpiece is. Two popular types of coolants were employed in this investigation. Emulsion is a mixture of 90% water and 10% oil. The first operation employed this kind of coolant. For the second procedure, synthetic oil is employed as coolant. The third procedure, known as a dry operation, uses no coolant to compare various types. The identical tools and conditions were utilized in all three types of operations to create 30 pieces of work for each. To obtain the results, each sample was evaluated using a surface roughness tester. The findings of this investigation indicated that when it comes to surface roughness, emulsion operations are the best coolant to employ.
