【摘要】 PCD是最新的刀具材料之一，已在国内外采用，但目前多用于连续切削加工，对断续切削的应用和研究很少。本文就 PCD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。结果表明 PCD刀具也适用于断续切削加工。更多还原

【Abstract】 As an up－ to－ date tool material, PCD have been used at home and abroad. PCD tools are applied mostly in continuous cut at present, but there have few application and investigation on interrupted cut. 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. Experimental results have indicated that PCD tools are suitable for interrupted cut.更多还原
