Nowadays there's billet parts, machine parts, CNC stuff.

现有钢坯零件，机器零件，CNC 之类的。

All parts were precisely cut in a Computer Numerical Control, or CNC machine, following a free plan downloaded from the Internet.

所有的零部件都根据互联网上下载的免费方案计算机数字控制机床切割而成。

We're doing CNC milling, we're doing 3D printing, but we're trying to go beyond that.

我们正 CNC 削，我们正 3D 打印，但我们正试图超越这些。

These Computer Numerical Control, or CNC, machines, could run programs that instructed a machine to perform a series of operations.

这些计算机数字控制或 CNC 机器可以运行指示机器执行一系列操作的程序。

CNC machines were a huge boon to industry, not just due to increased capability and precision, but also in terms of reducing labor costs by automating human jobs – a topic we’ll revisit in a later episode.

CNC 机器对工业来说是一个巨大的福音，这不仅是因为能力和度的提高，而且还因为通过自动化人类工作来降低劳动力成本——我们将下一集重新讨论这个话题。
