milling machine
C1Technical/Industrial
Definition
Meaning
A power-driven machine used for shaping solid materials, especially metal, by removing material with a rotating cutter.
Any machine tool that uses a rotary cutter to remove material from a workpiece by advancing (or feeding) the cutter into the workpiece at a certain direction. The process is called milling.
Linguistics
Semantic Notes
The term is a compound noun where 'milling' specifies the type of machining operation and 'machine' denotes the tool category. It is a hyponym of 'machine tool'.

Conceptual Metaphor
A PRECISION SCULPTOR (it subtracts material to create a form).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating 'milling' as 'мельничный' (related to a flour mill). The correct technical term is 'фрезерный станок'.
- Do not confuse with 'шлифовальный станок' (grinding machine), which uses an abrasive process.
Common Mistakes
- Using 'milling machine' to refer to a lathe (which rotates the workpiece).
- Pronouncing 'milling' as /ˈmaɪlɪŋ/ (like 'smiling') instead of /ˈmɪlɪŋ/.
