Meanwhile, as a part needs high precision as flanging for example, flanging die with hyperbatic structure is described.

同时，以一翻边精度要求较高的零件为例，介绍了一种倒装式结构的翻边模。

The surface testing of aspheric and optical part is especially difficult, which is big scale and high precision.

尤其是大型高精度的非球面光学零件，面形检测难度更大。

Singh says that this could help speed up the design process by making it possible to have a high-precision part built in weeks rather than months.
