Performance Evaluation of TiAlN Coated Tungesten Carbide and CBN Tool During Hot Machining of OHNS Round Bar
Subscribe/Renew Journal
Hot machining is one method of machining easily hard materials. Heat is added to the cutting tool, resulting in a reduction in hardness and improved machining capabilities. During the hot turning process, the surface quality of the machined component improves. Cutting speeds, feed rates, and depth of cut for both CBN and TiAlN-coated tungesten carbide insert are optimised by trial and error. The effects of CBN and TiAlN inserts on hot turning and cold turning with minimal fluid application have been analysed in terms of power consumption, surface roughness, cutting force.
