Modeling and Simulation Based on Morphology of Machined Surface in High-speed Milling

The quality of machined surface is the key and difficult point for milling hardened steel. In this work, in order to improve the quality of machined surface, study on morphology of machined surface in high-speed milling hardened steel .The model of cutting trajectory in high-speed milling hardened steel was established. By studying the measure method on micro-unit of surface texture, the simulation model of machined surfacesmorphology in high-speed milling hardened steel was established. This work researched on rule that the different parameters influenced on surface morphology with simulation. The results show that, residual surface height significantly increases with the increase of space in row spacing direction , the residual surface height increases with the increase of feed per tooth , improving spindle speed is conducive to bettering the morphology of machined surface, machining inclination angle is little effect on morphology of machined surface, the cutting vibration is conducive to bettering the morphology of machined surface when the tool amplitude was below the threshold.
