通过对点式冲击刀具的理论和实验分析，探讨了如何优化设计使刀具受力最合理。
The problem of design optimization of the point attach bit is discussed through theoretical analysis and discussion of experimental results.
本文通过对冲击采煤机冲击刀具的设计及其参数的研究，设计了较为合理的楔形冲击刀具。
Wedge impact blade of impact cutting coal machine was designed and its working process was stimulated.
切削刀具最重要的性能是在高温下能保持的硬度、耐磨损和冲击韧性。
The most important properties of cutting tools are hardness at high temperature, wear resistance, and impact strength.
即使刀具很硬，也应当有足够的韧性，以承载切削初始时的冲击载荷，或应对因工件材料瑕疵所引起的波动。
Even though the tool is hard, it should have enough toughness to withstand the impact loads that come in the beginning of cut or to force fluctuations due to imperfections in the work material.
切削刀具还必须具有高强度才能抗振动和抗冲击。
Cutting tools must also have high strength in order to be vibration and impact-resistant.
研究结果表明：切削花岗岩时，受切削力及其冲击的作用，PDC刀具产生近乎平行岩石表面的磨损形式，磨损机理为机械作用引起聚晶金刚石层微观裂纹产生并扩展而导致的金刚石颗粒的微观破碎。
The study shows that in granite cutting processes, PDC cutter is worn by micro chipping in diamond grains due to mechanical action, and the wear surface is almost parallel to the rock surface.
本文就PC D刀具断续切削铝合金时的切削力、切入冲击力和刀具磨损等问题进行了试验研究。
An experimental study on cutting force, cut - in impact force and cutting - tool wear are conducted in the interrupted cutting of aluminum alloy with PCD tools.
采用这样的方式，刀片被压块压住的面积比较大，不会因为受到某些力冲击的时候，使刀具报废。
When the method is used, the area of the cutter blade pressed by the press block is relatively large, so the cutter is prevented from being damaged due to the certain impact force.
