Effects of cutting conditions on the machinability of stainless steel formed by laser cladding
The paper investigates the effects of cutting conditions on the machinability of stainless steel coatings manufactured onto AISI 1045 steel by laser cladding technology.Two kinds of CBN (cubic boron nitride) tools with different comer radius and two different depths of cut were adopted in the experiments.Cutting force during machining,surface roughness and microhardness of machined surface were measured and analyzed.The results show that both the cutting force and surface roughness increase with the increase of depth of cut.When the other cutting parameters are identical,the surface roughness decreases with the increase of tools comer radius while the variations of different cutting force components present different tendencies.The microhardness of the machined surface and its varied gradient in the direction of depth of cut increase with the increase of tools comer radius.The experiment results will provide valuable suggestions for optimization of cutting performance for laser cladding coatings in order to obtain excellent surface quality.
