He took up a knife, and with the flat part of it played a tune on his cheek in a wonderful manner.
他拿起一把小刀，用刀面在自己脸上以一种巧妙的方式演奏了一支曲子。The highest cutting temperature point is always at face near the cutting edge.
切削温度的最高点总是位于前刀面上距离刀刃不远的地方。Gear Shaper Cutters Rake Face for the concave conical surface, so the formation of the lateral edge of anterior horn.
插齿刀前刀面的凹锥面，所以对前角外侧边缘形成。The results show that the diffusion wear of hard phase is intensified after the tear and shear of the adhering layer on the flank.
研究结果表明：后刀面粘结层的撕裂加剧了硬质相的扩散磨损；It can be see that the flank of the eng edge of ball-nose end milling cutter can be grinded by multi-axis tool grinder.
结果表明，采用多轴联动的工具磨床，可以实现球头立铣刀后刀面的磨削加工。Smart program control base on three layers or five layers card board, automatic sharpening, air cooled, blade oil spray systems.
智慧型程式控制，依据三层五层纸板规格，自动磨刀、空气冷却、刀面喷油等系统。As can be seen in Figure4-5, the geometry of a single-point cutting tool can be adequately described by six cutting angles.
在图4-5能被看见，一个单点切割工具的几何可以由六个刀面角充分地描述。The maximum tool effective stress is located in the flank face near cutting edge and the shear deformation zone on the workpiece.
最大刀具等效应力出现在前刀面上切削刃的周围，工件上最大等效应力出现在第一变形区。The reason for keeping the edge of knife sharp is that I found the gaps between bones are broader than the edge of my knife.
我能长久保持刀面锋利的原因是，我发现牛骨与牛骨之间都会有间隙，而我刀的锋面是极薄的。
