另一个被展出来民国三年袁世凯头像壹圆（Y329 type，不知是啥，可能是PCGS的标识吧）也有三种不同的齿边，一种也是普通的刻槽直齿边，一种呢，是被称作"希腊边"的样式，也就是字母"T"上下交叉排列设计的的一种齿边样式②，第三种齿边样式有点类似於鲱鱼的骨头，末端呈弯曲的样子，凸起阴刻的线条连接著这些凸起末端弯曲的像隔栅线③。

At last, the concept of effective cutting velocity is induced in, by changing the cutting results of cutter edge, a new type of shaving cutter with longitudinal tooth space is proposed and manufactured for the first time based on above analyses.

Ifs use finger shape milling cutter or a dish of shape piece of milling cutter adopt single tooth dispart law cutting time, cans process straight teeth, skewed tooth, a garden of stud gear and bring groove double helical gear or worm gear, this moment was processed gear's dentiform then by cutting tool become shape.

若用指形铣刀或盘形片铣刀采用单齿分度法切削时，可加工直齿、斜齿、园柱齿轮及带槽人字齿轮或蜗轮，此时被加工齿轮的齿形则由刀具成形。

In the incontinuous cutting, the wave shape of milling can be looked as periodic function. When the milling wave shape with single-tooth was looked as impulse function, by the Fourier Transform, we can find out that it is composed of sine wave with a given frequency and a series of integer multiple frequency. Discussing on the power function is a major tache for studying on the cutting capability of the complex three-dimension groove milling inserts, so to know the facts that affect the single-tooth milling spectral value, and to observe the dynamic milling wave property from the composition of the power spectral, thus we can design and optimize grooves.

在断续切削中，铣削波形可被看作周期函数，将单齿铣削波形看成为脉冲函数，经过傅立叶变换，可以表示为一个按特定的基本频率变动的正弦波形的分量和许多个按基本频率的整数倍而变动的正弦波形的分量叠加而成，讨论所获得的频谱函数，是研究三维复杂槽型铣刀片切削性能的主要环节，以便了解影响单齿铣削波形幅值谱图的各种因素，并从功率谱图的组成情况来考察动态铣削波形的特性，从而进行槽型的设计和优选。

Especially in processing of the special metallic materials. According as the adaption orthogonal tool edge bottom diameter and scraps' groove of taps ,using computer aid design the taps' trough shapes of taps, in order to tangency of the orthogonal .scraps' groove and tool edge' hack angle, making the scraps into streamline rolling scraps.

尤其被加工材料是特种金属时，根据丝锥所适合的前角、刃瓣、心径以及所允许容屑槽大小，运用计算机辅助设计改进丝锥槽形，使得丝锥前角、槽底圆弧以及齿背角光滑连接，切屑成流线形卷屑。

Fruit ovoid, slightly compressed dorsally; ribs thick-obtuse, very prominent, irregularly denticulate especially along ribs, denticles stiff-membranous or with stiffly scarious-processes and hairs; furrows narrow; vittae 1 in each furrow, 2 on commissure.

背的果卵球形，稍压扁；棱厚钝，突出，不规则具小齿特别沿着棱，小齿硬膜质或具硬突起和毛；棱槽狭窄；油管每棱槽1，在合生面上2。

The integrated circuit and the magnet are configured into a sensor package, such that the magnetoresistive bridge components enable the detection of a target tooth when one half of the plurality of magnetoresistive bridge components come into proximity with an edge of a tooth before that of another half of the magnetoresistive bridge components as the tooth and an associated slot thereof pass by the sensor package.

将集成电路和磁体配置到传感器封装中，使得磁致电阻桥式组件在目标齿及其相关槽通过传感器封装期间，在多个磁致电阻桥式组件的一半在磁致电阻桥式组件的另一半之前靠近齿的边缘时，能够探测到目标齿。

The cutting pattern and load curves of cutting process of the two cutting heads were given by computer simulation, which showed that the cutting performance of the cutting head with pick arrangement based on equal-rise-angle spiral line was good because of its reasonable pick cut, its uniform cutting pattern and the small value and the fluctuation of its load.

为了评价利用等螺旋升角进行截齿排列设计的截割头的截割性能，选用了一个实际的截割头进行比较，通过计算机仿真获得两个截割头截割过程的切屑图和载荷曲线，经比较分析表明，用等螺旋升角排列截齿的截割头截槽合理，各段切屑图均匀，载荷大小及其波动较小，截割性能良好，所以用等螺旋升角排列截齿是一种高效、实用的截齿排列方法。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.
