摘要

本文乃利用碳化鎢車刀磨成不同幾何形狀的刀角及刀鼻半徑，藉著其在車削過程中所造成的剪切面積變化，建立單鋒刀具的三維切削力學模式，並利用最小能量法以預測三維切削力量，結果顯示理論值與實驗值極為接近。切削實驗中，並做了切屑與工件表面光度的探討，以尋找較佳的刀真形狀及諸角度，結果發現切邊角約為30度時是一理想的角度。

The tungsten carbide tools are ground by us, which make them be various specifications. The variations in shear plane areas occurring in turning situation are used. A three dimensional force model for a single-point tool is proposed by minimum energy method in the present study. The results of the turning experiments show that the experiment data are close to the theoretical values. Cutting experiments were conducted by using medium carbon steel to study the mechanism of main chip formation; the surface roughness of workpiece and the ideal tool geometries were observed. Among the various sets of cutting experiments designed and performed in this research, it shows Cs≒30 would be an ideal tool geometrical.
