切屑

The shear angle in the shear plane will crease with the cutting velocity.

切屑剪切平面之剪切角会随著切削速度的增加而增加。

These flakes, in turn, reduce the strength of the secondary shear zone, decreasing tool-chip interface and wear.

这些片状，依次减小第二剪切区中的力量，降低刀具和切屑接口处的摩擦和磨损。

It is proposed that the value να, which is a product of grinding speed and undeformed chip thickness, is an important parameter determining the deforming mechanism of material at the grain shearing zone.

并首次提出磨削速度ν与未变形切屑厚度α的乘积να是决定磨粒剪切区变形机制的重要参数。

Wear model and characteristics of the second cutting deformation zone,that is,between the rake face of cutter and chips were investigated by carrying out diamond PCD cutter ultraprecision machining test of SiC noncontinuous reinforced aluminum composites,and measuring analysis with atom force microscope and scan electronic microscope.

通过金刚石PCD刀具对非连续S iC增强铝基复合材料的超精密车削加工试验，考察了刀具第二切削变形区的摩擦磨损性能，并提出了相应的模型；采用爆炸式快速落刀装置制备出切屑根并分析了积屑瘤的影响因素；采用原子力显微镜对PCD刀具的刃口磨损形貌进行观察，并分析其磨损机理。

The finite element model was build in high speed cutting bearing steel GCr15, the key technologies such as chip septated and interface frition were studied.

研究了切屑分离、刀屑摩擦等关键技术，建立了轴承钢GCr15高速切削的有限元模型。

Turning peripheries where there are no big variations of cutting parameters.

属半封闭断屑槽，前角为20°左右，适用于切屑用量变化不大的外圆车削。

With a higher wire speed and feed force, the feed rate increases which is benefit to a higher cutting efficiency.

由于硅晶体的断裂韧性小，锯切时容易形成破碎状切屑，去除率高于陶瓷。

Having analysed the effects of side flow of chips and cutting edge interference on angle of chip flow ,a calculation equation, which is practical in a certain range,is bac up through experimentS and begion analysis.

在分析切屑横向流动及切削刃干涉对流屑角影响规律的基础上，通过试验并利用回归分析的方法，建立了在一定范围内实用的流屑角计算公式。

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。

The model enables to predict the chip flow angle , which is based on the principle that the material removal in cutting process flows up along the direction of minimal cutting .

把主切削刃的斜角切削看作是一系列宽度狭窄的斜角切削排列起来，从而推导出主切削刃的总切削功率为包含切屑流屑角的函数表达式。

I am accused of being overreligious," she said in her quiet, frank manner,"but that does not prevent me thinking the children very cruel who obstinately commit such suicide.""

客人们在卡罗利娜·埃凯家里，举止就文雅一些，因为卡罗利娜的母亲治家很严厉。

Designed by French fashion house Herm è s, this elegant uniform was manufactured in our home, Hong Kong, and was the first without a hat.

由著名品牌 Herm è s 设计，这件高贵的制服是香港本土制造，是我们第一套不配帽子的制服。
