CNC machining spans a large U.S. workforce, specialized production roles, international machine-tool markets, and measurable energy and maintenance outcomes. The statistics below distinguish CNC-specific categories from broader machinist occupations and identify whether each figure is observed, surveyed, estimated, or forecast.

U.S. CNC Machining Workforce Statistics
The Bureau of Labor Statistics combines manual and CNC workers in the machinist occupation, so these figures describe the broader machining workforce unless a CNC category is named explicitly. In 2025, the United States had about 288,300 machinist jobs, while fabricated metal product manufacturing represented 35% of machinist employment, machinery manufacturing 21%, and transportation equipment manufacturing 13% (BLS Occupational Outlook Handbook).
BLS’s 2025–2035 projections separate machinists from tool-and-die makers but also provide a combined view:
| U.S. occupation measure | Period | Figure |
|---|---|---|
| Machinists | 2025 | 288,300 jobs |
| Machinists | 2035 projection | 291,200 jobs; 1% increase |
| Tool-and-die makers | 2025 | 56,700 jobs |
| Tool-and-die makers | 2035 projection | 51,500 jobs; 9% decrease |
| Machinists and tool-and-die makers combined | 2025 | 344,900 jobs |
| Machinists and tool-and-die makers combined | 2035 projection | 342,700 jobs |
BLS projects about 30,400 annual openings for machinists and tool-and-die makers during 2025–2035, including replacement needs. These are forecasts, and the machinist occupation includes both manual and CNC work (BLS Occupational Outlook Handbook).
The occupational definition also indicates the precision expected in the work. BLS gives accuracy within 0.0001 inch as an example and describes CNC machinists as programming three process parameters: cutting path, cutting speed, and feed rate; neither figure is a national production average (BLS Occupational Outlook Handbook).
Machinist Pay and Geographic CNC Data
BLS Occupational Employment and Wage Statistics data for May 2023 counted 290,720 U.S. machinists, with a mean hourly wage of $26.25 and a mean annual wage of $54,600. The median hourly wage was $24.44, while annual wages ranged from $36,690 at the 10th percentile to $75,820 at the 90th percentile (BLS Machinists).
Industry and state comparisons show why geography and application matter:
| May 2023 U.S. machinist measure | Employment | Mean annual wage |
|---|---|---|
| Machine shops; turned products; screw, nut and bolt manufacturing | 74,570 | $51,770 |
| Metalworking machinery manufacturing | 20,630 | $52,100 |
| Aerospace product and parts manufacturing | 15,010 | $63,140 |
| Michigan | 23,720; 5.46 per 1,000 jobs | $50,420 |
| California | 20,500; 1.14 per 1,000 jobs | $60,280 |
| Indiana | 16,450; 5.21 per 1,000 jobs | $51,700 |
These are employer-survey estimates and exclude self-employed workers. The occupation is broader than CNC-only employment, so the table should be read as machinist labor-market data rather than a direct census of CNC operators (BLS Machinists).
CNC Production Roles and Industry Demand
May 2024 BLS industry-chart data identifies CNC-related roles more directly while still separating them from machinists, programmers, supervisors, and inspectors. The counts show the scale of production ecosystems around machine tools, not a single CNC occupation total (BLS Data Tables for OEWS Industry Charts).
- U.S. metalworking machinery manufacturing employed 21,690 machinists, 12,210 computer numerically controlled tool operators, and 9,790 tool-and-die makers.
- U.S. machine shops, turned-product, and screw/nut/bolt manufacturing employed 73,870 machinists and 36,600 computer numerically controlled tool operators.
- The same machine-shop industry group employed 16,460 first-line production supervisors and 13,430 inspectors, testers, sorters, samplers, and weighers.
- It also employed 8,070 grinding, lapping, polishing, and buffing machine-tool workers, a related category that is not necessarily CNC-controlled.
- U.S. machinery manufacturing in the listed NAICS 3331, 3332, 3334, and 3339 industries employed 31,570 machinists.
- U.S. aerospace product and parts manufacturing employed 20,440 machinists and 13,780 computer numerically controlled tool operators.
The category boundaries matter: programmers may be classified separately, supervisors may oversee mixed manual and CNC processes, and inspection and finishing categories are broader than CNC inspection or CNC equipment alone. These BLS counts therefore help describe industry demand without relabeling every production role as CNC-only.
CNC Machine-Tool Markets and Adoption Trends
Trade.gov reports Japan’s industrial machine-tool hardware market using local production plus imports minus exports; software is excluded. The series, based on Japanese industry and government sources, shows the observed market-size decline through 2024 and an estimate for 2025 (Japan – Industrial Machine Tools).
| Japan industrial machine-tool measure | 2022 | 2023 | 2024 | 2025 estimate |
|---|---|---|---|---|
| Local production, US$ millions | 8,207 | 7,486 | 5,951 | — |
| Market size, US$ millions | 6,091 | 5,675 | 4,771 | 4,169 |
Trade.gov reports that 80% of Japanese companies used digital technology in 2023, compared with 50% in 2019. This is a broad digital-technology measure, not a CNC-specific adoption rate, so it signals an industrial-digital context rather than the share of firms operating CNC machines (Japan – Industrial Machine Tools).
CNC Energy, Material and Operating Cost Data
Older estimates remain useful for understanding scale, but they are not current inventories. A 2014 DOE peer-review project estimated that the U.S. installed CNC machine-tool base consumed 14.48 million metric tons of CO2-equivalent per year and 8.22 trillion BTUs per year (Sustainable Manufacturing).
For a representative machine, the same DOE lifecycle estimate reported 65.16 metric tons of CO2-equivalent and 37 million BTUs per machine-year. Across the machine’s estimated life, the table reported 782 metric tons of CO2-equivalent and 444 million BTUs; machine lifetime, utilization, and electricity mix assumptions are not universal (Sustainable Manufacturing).
The DOE project also estimated $1.14 billion in tooling-cost savings and a $24 billion reduction in cutting-fluid costs from its proposed manufacturing-technology improvement. Those are project estimates, not realized national savings or current CNC-only totals (Sustainable Manufacturing).
NIST cited a 2003 University of Tennessee study estimating annual U.S. industrial maintenance expenditure at $500 billion to $700 billion, with condition-based and proactive maintenance potentially saving $100 billion to $200 billion annually. These are broad industrial estimates, not CNC-specific realized savings (Programs of the Manufacturing Engineering Laboratory).
A 2021 CNC Speedwell project in Brownhills, West Midlands, found that 70 of more than 100 CNC machines had individual cooling units before a centralized-cooling project. The project received a £237,291 Industrial Energy Transformation Fund grant against £1,152,388 in project costs, and the company expected more than an 80% reduction in annual cooling-process energy consumption and related emissions; that reduction was a forecast, not a measured post-installation result (IETF Phase 1, Spring 2021: competition winners).
Measured CNC Productivity, Maintenance and Process Outcomes
NIST’s cited 2003 aerospace-plant example reported typical machine-tool spindle life averaging 40 to 400 operating hours and consumption of 1,000 spindles per year. It is a single large aerospace manufacturing plant example, not a national average (Programs of the Manufacturing Engineering Laboratory).
Two later demonstrations provide narrower, intervention-specific results:
- A 2012–2013 peer-reviewed cloud-energy-management demonstration at a CNC machining factory reported 12.5% energy savings after improving its compressed-air system; the result came from one demonstration site and cannot be generalized to all CNC factories (The Development of Cloud Energy Management).
- A 2019 peer-reviewed CNC face-milling experiment on AISI 1045 steel reported a 20.7% reduction in energy consumption using optimized Cu-nanofluid small-quantity cooling lubrication; this was a laboratory trial with one material, machine, tool, cooling method, and parameter set (Multi-Objective Optimization of Energy Consumption and Surface Quality in Nanofluid SQCL Assisted Face Milling).
- The reported optimum in that experiment used a 1,200 rev/min cutting speed, 320 mm/min feed rate, 0.5 mm depth of cut, and 15 mm width of cut; these settings are experiment-specific rather than universal CNC parameters (Multi-Objective Optimization of Energy Consumption and Surface Quality in Nanofluid SQCL Assisted Face Milling).
Together, the evidence separates workforce scale and market indicators from machine-level outcomes. Occupational counts describe people, market figures describe hardware, and demonstrations or laboratory trials describe particular interventions under stated conditions.
