群钻钻削力研究（Ⅳ）──群钻钻削力预测模型

Study On Drilling Forces of CMFD(Ⅳ )── The Prediction Model of the Drilling Forces in CMFD(Chinese Multi-Facet Drills)Drilling

提出了群钻钻削力预测模型．初步试验结果表明，钻削轴向力的预测值与实测值较为一致．

The prediction model of the drilling forces in CMFD drilling is proposed.The results in initiative test indicate that the prediction value of drilling thrust(axial force) is well coincident with the measured value.
