加工非球面聚光镜样板和细磨模,过去一般用放大图在投影仪上检查,由钳工制作的办法。上述办法需要投影仪和较熟练的钳工,还要绘制精确的放大图,制作时需多次修改,比较麻烦。当然上述零件也可用坐标铣床加工。但我厂没有坐标铣床。所以我们采用了程序线切割的方法,这个方法虽增加了计算的工作量,但减少了加工的工作量。下面谈谈我们的计算过程。 Processed aspheric condenser model and fine grinding mold, in the past generally use the magnifier to check on the projector, made by fitter approach. The above methods require projectors and more skilled fitter, but also to draw an accurate zoomed in map, making multiple changes need to be more troublesome. Of course, the above parts can also be used milling machine coordinates. But my factory does not have the coordinate milling machine. So we adopted the method of program line cutting, although this method increases the computational workload, but reduces the workload of processing. Here to talk about our calculation process.
