硬质合金钻头钻削铝合金的切削力实验研究

摘要

By the method of combing experiment analysis with experience modeling method,the cutting force and its change rule are studied,when the carbide drill is cutting aluminum alloy, the influence law of cutting parameter on the cutting force is analyzed. At the same time,by analyzing experimental data of three-dimensional dynamometer, chip morphology of microscop-ic observation,and observing under scanning electron microscopy, the working regularity of cutting actors on cutting mecha-nism,surface quality and the chip morphology is further revealed.%采用实验分析和经验建模相结合的方法对硬质合金钻头切削铝合金时的切削力及其变化规律进行了研究，重点分析了切削用量对钻削力的影响规律。同时通过对三坐标测力仪所得实验数据的分析、显微观察切屑的形态及扫描电镜下观察等手段，进一步揭示切削要素对切削机理、表面质量和切屑形态等的作用规律。
