削角

The current involute spline broach is analyzed,the grinding technology of involute spline broach with side clearance is described,the profile is designed,and profile error is analyzed.

分析了现有渐开线花键拉刀的缺陷，提出带侧刃后角的渐开线花键拉刀的磨削工艺，并进行了齿形设计及齿形误差分析。

Anterior horn and then grinding, increasing chip capacity space (for the shape of chip capacity and processing characteristics, especially with a tool to compare the Japanese brands and found that much better than those of their cutting effect, the specific part in the second straight shank cutter for a brief introduction), to avoid an increase in milling tool when rapid accumulation of the phenomenon of chip.

然后修磨前角，增大容屑槽空间(针对容屑槽形状以及加工特性，特地与某日本品牌刀具作比较，发现远远优于其切削效果，具体在第二部分直柄立铣刀作简单介绍)，避免在加大走刀量快速铣削时出现切屑堆积现象。

Car at both ends of cutting surface, drilling central hole of the cylindrical Rough →→→ quenched Hole Research Center Xiu → semi-refined car of the cylindrical tank cars →→→ chamfering hobbing milling keyway →→→ Hole Research Center repair mill → test cut.

下料→车两端面，钻中心孔→粗车各外圆→调质→修研中心孔→半精车各外圆→车槽→倒角→铣键槽→滚齿→修研中心孔→磨削→检验。

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

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
