Experimental Study on Surface Roughness of HSM Hardened Steel
Zha Wenwei He Ning
The influence of the different geometric parameters of the milling cutters (the rake angles, clearance angles and helix angles) ,the hardness of workpiece and the cutting parameters(the milling speed,the feed of per tooth)on the surface roughness of milled workpiece is studied with the experiments of high-speed milling hardened 40CrNiMoA and Cr12MoV steels. The change rule of surface roughness of the milled workpiece is obtained by analyzing the experimental data.
