So based on the experiments of high speed dry turning hardened steel ( Cr12 ) with ceramic cutter made in China the author studies the dynamic characteristic of cutting process , then proposes a dynamic cutting force modeling and a surface micro-topographic modeling .
本文在实验的基础上对高速硬车削过程进行了研究，针对高速车削淬火钢Cr12的特点，建立了动态切削力数学模型及表面微观形貌数学模型。
