随着数控线切割机的广泛应用,程序编制的计算问题日益为人们所关心,国外除采用自动编程外,也有采用人工编程的。如日本在使用点位及直线切削数控装置加工时,甚至使用连续切削数控装置,但加工形状较为简单时,都广泛采用人工计算制作指令纸带的方法,其工具是台式电子计算机和数学用表。并介绍了两个求交点的通式:
With the wide application of CNC wire cutting machine, the programming problem of programming is becoming more and more concerned by people. In addition to using automatic programming in foreign countries, there are also some manual programming. Such as Japan, the use of point and linear cutting CNC machining, even the use of continuous cutting numerical control device, but the shape is relatively simple, are widely used to manually calculate the instruction paper tape method, the tools are desktop computers and math tables . And introduced two general formula for intersection:
