Three kinds of cutting material were selected to machine stainless steel machining experiment such as ceramic cutting tools, cermets cutting tools and coated carbide cutting tools, in which the best range of each kind of tool material was founded. For example, LT55 was suitable to be machine lCrl8Ni9Ti as the cutting speed surpasses 120m/min and have a good wearable property.(3) Surface roughness was measured under different cutting conditions. Feed rate played the most important role in impacting surface roughness, and then cutting speed.(4) Chip patterns in different cutting speed with various cutting materials were analyzed. With the increase of turning speed, chip became shorter and was easy to be broken. For instance, serration chip appeared in high sped turning stainless steel with LT55;(5) Work hardening of austenitic stainless steel was analyzed.

This paper also makes a experimental study of the regularities of the outstripping machining in aspects of machine tool, cutting tool, cutting conditions and so on, and points out that the outstripping phenomenon occurs on the following conditions: the machine tool with high precision, the PCD cutting tool with small clearance and lay angle, the small installation angle, the small feed rate and the cutting lubricant with good properties, and that the cutting speed and the depth of cut have no effects on the outstripping machining.

本文还从机床、刀具和切削条件等方面对超越性加工的规律进行了实验研究，指出超越性加工现象是在如下条件下产生的：较高精度的机床、后角和刃磨纹理角较小的PCD刀具、较小的安装角和较小的进给量以及冷却润滑性能良好的切削液，而切削速度和切削深度对超越性加工几乎没有影响。

On the basis of above studies, the work is aimed at examining the main factors which affect the high-speed milling and the optimize calculations of them. It especially carries out the analysis for the affect of the feed speed、tool angle and shape of tooth. Lastly, in this paper all above with theories and tests results have been explained.

在上述分析研究的基础上，本文讨论了超高速切削条件下影响超高速铣削加工的主要因素，重点分析了进给速度、刀具角度和刀具形状的影响，对各影响因素进行了优化计算，并结合试验进行了分析说明。

Simultaneously, on the premise of ensuring strength and toughness, the hardness and red-hardness are improved.

同时，在保证刀具强度和韧性的前提下，提高了刀具的硬度和红硬性。

The CL data file can be converted to NC code with NC post module of Pro/E, which can shorten design cycle of tricone rock bit, improve design quality and enhance the competitive capacity and innovative ability of enterprises.
