标准麻花钻钻削力的相似预测

Outting Force Prediction Based on the Geometric Similarity between Krills

本文应用相似理论的原理和现有的切削模型，以很少的切削力数据，简单实用求不同直径麻花钻头钻削力．通过钻削实验确认了钻头切削力相似预测的正确性及适用性．

In this paper,using the concept of the cutting models and similarity Conditions we get easily the torgue and thrust for drills of various diameters,according to a little datc of cut-ting forces. An drilling experiment has been made and provcs that is correct and applicable.
