machine tool
C1Technical / Industrial
Definition
Meaning
A powered mechanical device used to shape or form solid materials, especially metals, by cutting, boring, grinding, shearing, or other forms of deformation.
More broadly, any automated or computer-controlled device used in manufacturing. Sometimes metaphorically extended to describe a person or system that operates with mechanical precision or without independent thought.
Linguistics
Semantic Notes
The term is a compound noun where 'tool' is the head (it's a type of tool) and 'machine' modifies it. It's a hyponym (specific type) of 'machine'. Not all machines are machine tools (e.g., a car is a machine, not a machine tool).
Dialectal Variation
British vs American Usage
Differences
The term is identical in form and primary meaning. Minor differences exist in associated vocabulary (e.g., 'lathe operator' vs. 'turner' is more common in UK historical contexts).
Connotations
Identical industrial/technical connotations.
Frequency
Slightly higher frequency in AmE due to larger historical manufacturing discourse, but the term is standard in both varieties.

Usage
Context Usage
Business
Discussed in contexts of capital investment, industrial capacity, manufacturing efficiency, and supply chains.
Academic
Used in engineering, industrial design, manufacturing technology, and economic history texts.
Everyday
Rare, except when discussing manufacturing jobs or technical hobbies (e.g., home workshop).
Technical
The primary register. Specified by type (lathe, mill, grinder, drill press), control system (CNC, manual), and capability.
Examples
By Part of Speech
verb
British English

Learning
Memory Aids
Mnemonic
Imagine a TOOL so big and powerful it needs its own MACHINE engine. It's a MACHINE that is also a TOOL.
Conceptual Metaphor
INDUSTRY IS PRECISION / THE FACTORY IS A BODY (where machine tools are the skilled hands).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct calque "инструмент машины" (tool of a machine). Use standard "станок" or "металлорежущий станок".
- Don't confuse with "machine" alone (машина) or "tool" alone (инструмент). The compound is a specific technical term.
Common Mistakes
- Using 'machine tool' to refer to any power tool (e.g., a handheld electric drill).
- Spelling as one word: 'machinetool'.
- Incorrect plural: 'machine tool' (singular), 'machine tools' (plural).

FAQ
Frequently Asked Questions
Traditionally, no, as classic machine tools are subtractive (remove material). 3D printing is additive. However, advanced hybrid manufacturing systems that combine both are blurring this distinction.
Computer Numerical Control. It means the machine's operations are directed by a computer program.
All machine tools are machines, but not all machines are machine tools. A machine tool is specifically designed to shape rigid materials. A car, a dishwasher, or a crane are machines but not machine tools.
Rarely. The hyphenated form 'to machine-tool' exists in very technical contexts, meaning to work on something using a machine tool. The simpler verb 'machine' is far more common.
