Tool Wear and Surface Roughness in Turning AISI 8620 using Coated Ceramic Tool
- The purpose of this research paper is to study the tool wear and surface roughness of AISI 8620 material using coated ceramic tool by turning process. Ceramic cutting tools have outstanding material hardness, resistance to high temperatures, wear resistance, chemical stability and hot hardness. Ceramic tool with Al2O3 + TiC (golden) coating was used to investigate the surface roughness and tool wear on AISI 8620 material without coolant. The tests were carried under various combinations of cutting speed, feed rate, and depth of cut and fixed time period. Surface finish is an important attribute in any machining operation. Surface roughness decreased when the cutting speed was increased and tool wear was not noticeable for a few tests. It increased rapidly at higher cutting speed, feed rate, higher depth of cut and increase in time. The flank wear, crater wear and nose wear were measured. During turning, built up edge formed and was due to diffusion of the work piece material. Key wor...
