高硅氧玻璃纤维／酚醛树脂复合材料切削力的试验研究

Cutting Force of High Silica Glass Fiber/Phenolic Resin Composites

通过用PCD刀具对高硅氧玻璃纤维/酚醛树脂复合材料的车削试验,采用正交试验和回归分析法,研究了切削用量三要素对切削力的影响规律,建立了切削力的经验模型。结果表明,背吃刀量是影响切削力的主要因素,增大背吃刀量时主切削力和进给力都显著增大;增大进给量也使主切削力增大,但其影响小于背吃刀量;而切削速度对切削力的影响很小。所建切削力经验公式可作为切削加工该复合材料时切削用量选择及切削力控制的依据。

By turning tests on high silica glass fiber/phenolic resin composites with a polycrystalline diamond （PCD） tools, the influences of cutting parameters on cutting force were studied and the empirical model of the cutting force was established through orthogonal test and regression analysis. The results show that the effect of the cutting depth on the cutting force is the main factor;the main cutting force and the feeding force increases significantly with increase of the cutting depth ;with the increase of the feed rate, the main cutting force also increases, but its effect is less than that of the cutting depth;the cutting speed has little effect on the cutting force. The empirical model can be used as a basis for selecting the cutting parameters and controlling the cutting force when machining the composites.
