基于材料损伤理论确定了切屑分离准则
建立了钛合金TC4构件铣削过程的有限元模型
利用商业有限元软件(ABAQUS)
在给定切削参数条件下
采用不同几何参数(前角、后角、螺旋角)的刀具对钛合金TC4的铣削过程进行了有限元模拟
研究了切削力和切削温度随刀具角度变化的规律
结果表明:铣刀的前角在10°20°
后角为12°20°
螺旋角为30°45°时比较适合钛合金TC4的铣削。
The chip separation is determined based on material damage theory
the finite element model of titanium alloy TC4 monolithic component’s milling process is established.Under given conditions
the titanium alloy TC4 is milled by cutters with different geometrical parameters(rake angle、clearance angle、spiral angle)
the milling process of titanium alloy TC4 is simulated using commercial finite element software(ABAQUS)
the low the cutting forces and cutting temperature changed with cutter angle is studied
results show that:the milling cutter with rake angle between10°
2
0°
clearance angle between12°
0° and spiral angle between 30°
4
5° is proper to mill titanium alloy TC4.
