Simulation Research on High-speed Cutting Force of Quenched High-strength Steel
This paper employs the Abaqus finite element analysis software to establish the two-dimensional high-speed cutting simulation model of quenched 30CrNi2MoVA high-strength steel to study the stress distribution and edge defects of the workpiece during cutting,and adopts single factor method to study the effects of cutting speed and cutting depth on the main cutting force.The results show that during stable cutting stage,the magnitude and direction of the stress basically remains the same,the cutting angle keeps about 45°and finally changes to negative at the cutting out end,and the cutting force decreases;in the stable cutting stage,the increment of Fx with the increase of cutting speed is small;while Fx is increasing linearly with the increase of cutting depth,which proves that cutting depth has a greater impact on Fx.
