Experimental Study on the Thread Turning Performance of Two TiAlN Coated Thread Inserts with Different Features

Abstract:

With the development of the coating technology, coated tools have been widely used in processing industries. Thread turning is one of its applications. The performance of coated thread inserts varies with the change of coating material, coating thickness, matrix material and tool structure. Two tungsten-cobalt type alloy matrix, TiAlN coated thread inserts with different coating thickness, rake face type had been employed to conduct the thread turning experiments. By analyzing the cutting forces, chip formation and tool wear, it was found that insert with coating thickness of 4.35 μm would result in less tool wear under MQL condition, smaller cutting force, better chip morphology under dry condition compared with insert with coating thickness of 2.38 μm.
