运用离散法实现数控加工仿真

Simulation of Numerical Control with Triangle Surface Disperse Method

数控加工仿真的基础是三维实体的表示方法和图形学处理算法 .讨论了一种新的适合三轴数控仿真加工的三维实体表示方法 ,即三角面离散法 .针对三角面离散法 ,编写了直线走刀及弧线走刀的基本算法 .同时提出了一种新的图形学算法 ,即视向离散法 .达到了预期的效果 .

The base of numerical control simulation is the expression method of 3D solid and graphic arithmetic.The first emphasis of the article is on the appropriate method for three axes numerical control emulation to specialize the 3D object,a way named triangle surface disperse method,giving the basic arithmetics for line-track and arc-track.The second is on a new graphic's arithmetic,visual disperse method.
