下刀具

Therefore, Fine copper fibers with stability quality were obtained under setting back engagement for 0.04-0.06mm, cutting speed for 30-60m/min and feed for 0.72-1.44mm/str, and using the tool with rake angle and clearance angle were 30° and 8°, respectively.

在背吃刀量为0.04-0.06mm，切削速度为30-60m/min，进给量为0.72-1.44mm/str的条件下选择前角为30°，后角为8°的多齿刀具，可以获得质量稳定的微细铜纤维。

The effect of rake angle and cutting velocity on the shear strain imposed in the chips, microstructure and hardness of chips are highlighted in a variety of metals and alloys.

本文对比了不同的金属和合金在各种刀具前角和切削速度条件下，切屑上产生的剪应变、切屑的微结构及其硬度的变化规律。

It also elaborates on the reasonable choices of the geometric parameters and cutting parameters of the cutting tool materials, cutting tools to ream, drill and mill high strength steel and super-high strength steel.

在选择切削速度时，在工件材料的强度和硬度较高的情况下，应适当降低切削速度，减小刀具每齿进给量，按工件材料的强度选择铣削速度，按工件材料的硬度选择铣削用量。

In this paper an innovative method for machining sculptured surfaces is presented. By using a disc cutter with a concave end instead of traditional ball-ended or drum-shaped tools, and adjusting the cut- ted axis to swing relative to the component being machined under some special rules, the envelope formed by the trace of the tool-nose may have the same derivative up to the third order as the required theoretical surface.

本文提出了一种加工自由曲面的新方法，即采用中凹的盘形铣刀取代传统的球头或鼓形铣刀，在每一行程中让刀具轴线相对于工件按特定的规律摆动，使得在垂直于进给方向的法截面中，由刀尖轨迹形成的包络面与理论曲面的法截线具有相同的1～3阶导数，从而在保持精度不变的前提下，使实际行程次数得以大幅度的减少。

Early in 1893, a mechanical watch manufacturer Ashler Mate in a town, which was the industrial town of north-west part of Switzerland, invented and made the original form of 'Wenger'. In 1900, Theo Wenger and Henri Sandoz, the president of Dawanashi, cooperated to register Wenger Co. and move its headquarter to another town.

早在1893年，瑞士西北部工业重镇尤拉地区的克特泰勒小镇上一位机械手表制造商阿希勒·梅特研制并生产了&威戈&组合刀具的雏形。1900年，在迪欧·威戈及塔瓦纳斯手表公司总裁亨利·桑多斯携手合作下，威戈公司正式注册成立并将总部迁至德雷蒙特市。

The result indicates that the imbalance of cutter bring the most important influence of cutter's vibration, distance error of teeth impacts cutter's vibration under dynamic cutting force. This method had been applied in the development of high speed face milling cutter.

结果表明：刀具不平衡量引起的离心力对铣刀自激振动影响最大，齿距差对动态切削力作用下的铣刀振动产生重要影响，该方法已应用于高速面铣刀产品研发中。
