摘　　要：硬态切削作为一种先进的加工技术,是提升切削加工表面质量的关键。本文对硬切削加工表面三维形貌进行研究,总结了切削参数和刀具磨损对硬切削加工表面形貌的影响规律。结果表明:切削速度和后刀面磨损对硬切削加工表面形貌有着较明显的影响。在中低切削速度切削参数范围内,随着切削速度的增加,加工表面三维粗糙度增幅较小,然而,在高切削速度条件下,表面三维粗糙度则增加较为显著。随着刀具后刀面磨损量的增大,加工表面三维粗糙度也明显增加;当切削速度增加到300m/min,后刀面磨损量超过0.15mm时,加工表面摩擦状态明显加剧,表面三维形貌出现明显恶化。As an advanced machining technology,hard cutting is the key to improve the surface quality of cutting.In this paper,3 D surface topography of hard cutting surface has been studied,and the influences of cutting parameters and tool wear on the surface topography of hard cutting have been obtained. The results show that cutting speed and flank wear have obvious influences on the surface morphology of hard cutting. In the range of medium and low cutting speed,the increase of the surface roughness of the machined surface is smaller with the increase of cutting speed,while the surface roughness increases significantly in the condition of high cutting speed. With the increase of the tool surface wear,3 D roughness of the machined surface also increases obviously. The friction state of the surface is obviously aggravated and 3 D appearance of surface is obviously deteriorated when the cutting speed reaches to 300 m/min and the rear wear is more than 0.15 mm.
