Question

机械英文翻译

The cutting edge along the side of an end mill is generally straight and sometimes can be tapered by grinding on a tool and cutter grinder such that the draft required for mould and die cavities can be automatically generated. Further, the end face can be square with the side as in the normal case or a ball end shape to be used for milling three dimensional contours such as in die cavities. It can also have a rounded corner for milling special round edged pockets as shown in Fig.7.10.
Large size end mills are called shell end mills, which do not have any shank and can be mounted with the help of a central hole. Consequently these can be used in horizontal axis as well as vertical axis milling machines. These will be mounted with the help of a stub arbor onto the spindle as shown in Fig.7.9.
Face milling cutters (Fig.7.12) are used for machining large, flat surfaces. They have the cutting edges on the face and periphery. They are generally mounted directly on the nose of the spindle with the entire face free for machining. The teeth on the face do most of the machining while those on side are used for cleaning the surface. These are generally made of carbide insert variety in view of the large material removal, though high speed steel is also used.
In connection with the milling cutter designation the following terms are often used.
Hand of cut This refers to the direction in which the cutter is rotated. When viewed towards the spindle, when the cutter is moving counter clock wise it is called right hand rotation while the opposite is called left hand rotation.
Hand of helix In case of helical milling cutters, when viewed from the end if the flutes move in a clock wise direction it is called the right hand helix while the opposite is called the left hand helix. The axial cutting force direction depends upon the hand of the helix. If two milling cutters of different helices are arranged side by side in a gang milling operation, the net axial force can be reduced to zero depending upon the cut taken by each of the milling cutters.
While selecting a milling cutter for a given application the following points should be considered.
(i) Use standard tools whenever possible.
(ii) Use a short overhang from the spindle and the largest possible mounting type.
(iii) Select a cutter diameter 30％ larger than the width of cut (face milling).
(iv) Use a close pitch cutter as first choice.
(v) Use a coarse pitch cutter for long over hangs and unstable conditions.
(vi) Use an extra close pitch cutter for short chipping materials and small radial depths of cut.
The slab milling cutter can have the cutting teeth, which can be straight and parallel to the axis of rotation. Alternatively they can be at an angle to the axis along a helix as shown in Fig.7.13.

最尖端沿立铣床的边通常是平直的和可以通过研有时逐渐变细在工具，并且切削刀研磨机这样对于模子是必需的草稿和死洞可以自动地引起。 进一步，末端面孔可以与边相符正常情况或为碾碎的三维等高将使用的球端形例如死洞。 如Fig.7.10所显示，它可能也有碾碎的特别圆的渐近的口袋圆角落。
大号立铣床称圆筒形端铣刀，没有任何小腿，并且可以在一个中央孔帮助下登上。 结果这些可以用于水平的轴并且垂直的轴铣床。 如Fig.7.9所显示，这些在纺锤上的一个残余部分树荫处帮助下将登上。
Face铣刀(Fig.7.12)为用机器制造大，平面使用。 他们有在面孔和周围的先锋。 他们任意直接地在纺锤的鼻子通常登上与整个面孔的为用机器制造。 当那些在边为清洗表面时，使用在面孔的牙做大多数用机器制造。 这些通常由碳化物插入物品种制成由于大物质撤除，虽然也使用高速钢。 与铣刀指定相关的以下期限是常用的。 裁减Hand这提到切削刀被转动的方向。 当观看往纺锤，当切削刀是明智时移动的逆的时钟它称右手自转，当对面称左手自转时。 螺旋Hand在螺线铣刀的情况下，当观看从末端，如果长笛朝时钟明智的方向行动它称右手螺旋，当对面称左手螺旋时。 轴向切削力方向取决于螺旋的手。 如果不同的螺旋二把铣刀肩并肩在帮会碾碎的操作被安排，净轴向力可以减少到零根据其中每一把采取的裁减铣刀。 应该考虑选择一把铣刀的While为一种特定应用下列问题。
(i)使用标准工具若情况许可。
(ii)使用从纺锤和最大的可能的架置类型的短的突出物。
(iii)大于裁减(端铣)的宽度选择一条切削刀直径30％。
(iv)首先使用一把接近的沥青切削刀作为选择。
(v)为长期使用一把粗糙的沥青切削刀垂悬和不稳定的情况。
(vi)简称使用切削材料和裁减的小辐形深度一把额外接近的沥青切削刀。
The平板铣刀可能有切口牙，可以是平直和平行的与转动轴。 如Fig.7.13所显示，或者他们可以是有一个角度到沿螺旋的轴。
