Based on the relevant movement between hard shaper cutter and grinding wheel, the movements of grinding wheel are studied. The shaping grinding point and the shaping grinding edge are made up with. In order to easily compare when shaping errors and cutting edge"s angles are the most excellent, uniform expressions for convex curved rake face of hard shaping cutter and spatial cutting edge curve are separately developed. The distributions of new profiling cutter"s shaping errors and cutting edges angles are analyzed. The relevant grinding wheel and cam are designed. Due to this paper, a new profiling hard shaping cutter has been manufactured successfully. At last experiments are made to test the performance of hard shaping cutter and all kinds of precision of hard gear.

本文直接从插齿刀与砂轮之间的相对运动关系出发，单独研究砂轮的运动，提出砂轮成形磨削点和砂轮成形磨削刃的概念；分别建立圆柱砂轮和圆锥砂轮磨削后硬齿面插齿刀的波形前刀面方程及空间切削刃方程；为便于比较何种情况下插齿刀的构形误差和切削角度能同时达到最优，分别对磨削五种不同硬齿面插齿刀所用的砂轮进行了廓形设计，并分析了插齿刀的构形误差和侧切削刃切削角度的分布规律；为插齿刀波形前刀面的磨削加工设计了相应的凸轮，用所设计的凸轮和近似的砂轮成功地制造出新构形法硬齿面插齿刀；最后进行插齿加工试验，检验新构形法硬齿面插齿刀的抗崩刃能力、耐磨性及被加工硬齿面齿轮的各项精度。

On the basis of several above-mentioned studies, the intermittent creep feed grinding with CBN wheel made from many CBN grinding blocks or with slotted CBN wheel, which is a new high efficient technical art combining the advantages of CBN wheel, intermittent grinding and creep feed grinding, has finally been recommended.

此项具有创新理论价值的研究成果填补了关于磨削基础理论研究的一项空白，同时，所获得的结果也确证了断续磨削在改善弧区换热条件、疏导弧区磨削热、抑制磨削液成膜沸腾过程降低磨削温度上的显著效果，从而提示了断续磨削可以作为大幅度开发缓磨潜力的一项极其有效的手段。

The high speed or super-high speed grindings force has the same variety regulation contrast to the common speed grinding, which can get the explanation from closely empirical formulas. Under the same grinding condition, the grinding force of laser trimming wheel is near to or slightly lower than the mechanical trimming wheel.

高速磨削力与普通速度磨削力具有相近的变化规律，这可从它们相近似的磨削力经验公式得到解释，在同一磨削工况下，激光修整砂轮的磨削力接近或略低于金刚石滚轮修整砂轮。

It combines rough and fine processes into one and achieves low metal removal rate as compared with cutting processes such as welding and milling.

它与普通磨削的区别在于很高的磨削速度和进给速度，而高速磨削的定义随时间的不同在不断推进。20世纪60年代以前，磨削速度在50m/s时即被称为高速磨削；而20世纪90年代磨削速度最高已达500m/s。

Knives and scissors grinding have different from other commonly product grinding. It has high grinding quantity, rigid surface, fin texture and so on, so it has the characteristic of one-off mighty grinding.

刀剪磨削不同于普通磨削，其磨削特点有磨削量大、表面硬度高、纹理细密等，属一次性强力磨削。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
