Translation error?

[MulleDK19]

As Nofsky said, perfectly acceptable to call a Chipper. Just as a Chipper is so named because of what it produces, so an object can be named by what it does.

There is no right or wrong way when you talk about the English language as it all depends on local slang, nicknames, changing usage, etc.

To me, its a perfectly acceptable translation.

So a horse carriage in the 18th century should be called a car?

A Chipper is a machine. Just like a machine that computes is called a Computer. But that doesn't mean that old mathemathical devices from the 18th century were called Computers.
