如何提升模具曲面加工精度？

I would like to create a mold with the highest possible accuracy and finish using a cutting machine. Do you know of any good ways to do it?

我想用切削加工机以尽量高的精度来加工这个模具的曲面，
有什么好的方法吗？

You should speed up the rotation of the ball end mill during the cutting process. This will improve the cutting quality and reduce burrs resulting in improved surface finish accuracy.

切削加工时，最好提升球头铣刀的转速。
这样可以增强刀尖的切削特性，抑制毛刺产生，提升加工面的精度。

What kind of measuring instruments would be good for checking the quality of the surface?

检查加工面的质量用哪种测量仪比较好？

How about a two dimensional laser displacement sensor?
You can measure the shape of the surface with a wide band of laser light.

二维激光位移计怎么样？
它能用带状的大范围激光测量表面形状。

确认会话中出现的单词！

• ・“切削加工” cutting
• ・“模具” mold
• ・“表面” surface

• ・“高精度” high accuracy
• ・“（最终）造成～” result in
