Rolling machine setters, operators, and tenders, metal and plastic correspond to O*NET 51-4023.00: they set up, operate, or tend metal and plastic rolling machines, adjust roll gap per work orders, monitor jams and thickness, measure finished product, and record anomalies.
Rolling machine operators set roll gap, guides, and material feed per work orders, and monitor the rolling cycle, jams, thickness, and surface defects; on anomalies they stop the machine and respond per procedure. The O*NET occupational scope covers both metal and plastic.
Adjacent to extruding and drawing machine setters, forging machine operators, cutting and punching machine operators, and industrial machinery maintenance workers; the core output of this occupation is rolled material that meets specifications, not repairing entire equipment sets.
O*NET 51-4023.00 covers setting up, operating, or tending metal and plastic rolling machines: read rolling work orders and drawings, adjust roll gap and guides, start the machine and monitor jams and operation, measure the thickness and shape of plate, strip, or structural shapes, correct defects, and record batches.
O*NET 51-4023.00 is a standalone occupation; 2025 wages and 2025—2035 employment both follow the same BLS occupational row and do not borrow statistics from adjacent machine tool workers.
2025 national manufacturing urban non-private sector pre-tax annual average wage (National Bureau of Statistics Table 2). The industry covers many occupations; for scenario reference only, not the wage of rolling machine operators.

Set up or operate metal and plastic rolling machines per work orders, adjust roll gap and guides, monitor jams, measure thickness, shape, and surface, and record batches and anomalies.
Extruding and drawing workers form material with dies, forging workers deform it with pressure, and industrial machinery maintenance workers disassemble and repair equipment; rolling machine operators focus on controlling continuous rolling and product dimensions.
The typical BLS 51-4023 entry is a high school diploma or equivalent with moderate-term on-the-job training, not a unified threshold for all employers.
AI can help organize work orders, trend records, and defect classification drafts; material condition, actual dimensions, roll gap, jams, and personnel safety must still be verified on site, and the model cannot automatically approve machine adjustment or return to service.
Before applying, verify the rolling mill type, material, roll gap and thickness measurement method, equipment guarding, energy isolation, shifts, scrap handling, and machine adjustment authority; practice materials are not connected to a real rolling mill.
The BLS 51-4023 standalone occupation had a 2025 median annual wage of 50,140 U.S. dollars; 2025—2035 employment falls from 25,300 to 23,200 (a decline of 8.3%), with about 1,900 annual openings. Chinese manufacturing average wages serve only as industry background.
Equipment operation｜Monitor the rolling mill cycle, guides, roll gap, and jams. Material differences｜Metal grades or plastic formulations affect the setup. Dimensional quality｜Thickness, shape, and surface defects must be inspected per the work order. Anomaly handling｜Stop immediately for jams, misalignment, or protective device anomalies. Physical environment｜Production lines may involve noise, heat, oil, and shift work. Process collaboration｜Hand over with feeding, quality, maintenance, and crew leads. Record traceability｜Keep material batches, equipment setups, and inspection results. Authorization boundaries｜Machine adjustment, repair, and return to service have employer-defined authority. Safe stop｜Never bypass guarding to enter the moving roll area.
Deliver rolled parts that meet dimensional and surface requirements, equipment setup records, inspection results, and anomaly handover; repairs and major parameter changes follow authorized procedures.
The BLS 51-4023 standalone row shows 2025 employment of 25.3 thousand and a 2035 projection of 23.2 thousand, a net decrease of 2.1 thousand and a decline of 8.3%; annual openings are still about 1.9 thousand, mainly from replacement.
Read work order and material batch → Verify rolling mill condition and guarding → Set roll gap, guides, and feed → Trial roll and measure → Continuously monitor jams and dimensions → Adjust or stop and escalate → Record batch and hand over
The National Bureau of Statistics 2025 figures of 113,594 yuan for non-private manufacturing and 76,055 yuan for private manufacturing are industry averages and cannot be equated with rolling machine operator wages.
O*NET lists tasks such as monitoring the rolling mill cycle, adjusting equipment settings, starting the machine to roll, inspecting raw material and finished product, reading work orders, and measuring dimensions.
The BLS 51-4023 figure of about 1,900 annual openings includes replacement needs; openings must not be seen as net employment growth or real-time hiring volume.
Verify work order specifications → Check material and roll condition → Set roll gap and guides → Trial roll and measure thickness → Monitor operation and surface → Isolate nonconforming product → Record setup and hand over
Material batches, roll gap setups, thickness records, and equipment alarms must be traceable; AI-organized anomaly summaries cannot replace measured values.
Keep work orders, materials, equipment numbers, roll gap, speed, temperature or cooling conditions, sampled dimensions, defects, and stop-handling records.

This module focuses on roll pinch points, jams, material condition, out-of-tolerance dimensions, equipment guarding, and handover; the fictional scenarios do not replace employer safety procedures.
The main boundaries are whether work orders and materials match, whether the rolling mill setup is verifiable, whether jams can be stopped, when product is isolated, and who has return-to-service approval authority.
O*NET provides tasks, and the risk scenarios are editorial simulations that do not represent incident rates or unified regulations.
Operators, feeders, and people near the equipment
Roll pinch points or material entanglement can cause serious injury.
Verify guarding and personnel positions, and never reach into the moving area; stop per procedure on anomalies.
Fictional: the plate is misaligned, and someone wants to reach in to straighten it.
Operators, quality staff, and downstream crews
Thickness gauge drift or missing sampling lets out-of-tolerance material pass through.
Verify calibration, sampling, and measured values, and isolate nonconforming batches.
Fictional: the thickness gauge calibration has expired, but the system still shows "acceptable".
Operators, maintenance staff, and equipment managers
Incorrect roll or guide setup causes jams, machine damage, or scrap.
Set up against the work order and trial roll to remeasure, and stop and hand anomalies to maintenance.
Fictional: after a roll change the guides were not re-verified, and the plate and strip continuously drift.
Operators, maintenance staff, and on-site personnel
Handling a jam without energy isolation can expose people to unexpected startup.
After stopping, isolate energy as authorized, and have designated personnel complete repair and return to service.
Fictional: after a jam, someone opens the guarding without isolating the equipment.
Operators, quality staff, and the customer
AI-generated parameters or quality descriptions may invent materials, units, or anomalies.
Recheck the work order, raw measurement values, and equipment instructions, treating model suggestions as drafts only.
Fictional: the model writes 0.8 millimeters as 8 millimeters.
Operators, the crew, and the people taking over
Unrecorded nonconforming batches or stop reasons may cause the next shift to release product by mistake.
Record batches, setups, measured values, isolation status, and return-to-service approval.
Fictional: the trial-roll sample is out of tolerance, but the handover only says "equipment normal".
O*NET is used to verify rolling mill setup, operation, and measurement tasks, not to measure incident rates.
The NIST framework is used for AI output governance, not as a substitute for equipment guarding procedures.
BLS standalone occupation statistics do not provide plant incident rates.
O*NET work context is used to understand the production environment, not as equipment instructions.
ILO research provides cross-occupation AI background and does not give incident rates for this occupation.
| Learn sampling, thickness measurement, and defect isolation |
| Able to identify instrument drift and nonconforming batches |
| Produce fictional thickness and isolation records |
| More focused on measurement and release evidence |
| Roll change and equipment collaboration trainee | Learn shutdown, energy isolation, and maintenance handover | Able to explain the boundary between operation and maintenance | Complete a simulated roll change handover sheet | Does not equal repair or return-to-service authorization |
| Plastic calendering trainee | Learn material temperature and roll surface condition | Able to distinguish metal and plastic process conditions | Complete fictional temperature and thickness records | Material and equipment windows differ |
Education and fundamentals
The typical BLS 51-4023 entry is a high school diploma or equivalent with moderate-term on-the-job training.
Real employers must train according to rolling mill, material, and guarding conditions.
Equipment authorization
Machine adjustment, jam clearing, repair, and return-to-service authority should be separated per employer procedures.
Verify supervision, energy isolation, and quality release requirements.
Task evidence
Work orders, roll gap, thickness, and anomaly records can show the process; relative predictive validity for hiring has not been verified.
Fictional cases show setup, measurement, and stop-work boundaries.
Collaboration and records
Reviewable information must be handed over with feeding, quality, maintenance, and the incoming crew.
Verify whether the person taking over can reproduce the problem from the records.
Practice setup｜All fictional, no connection to a real rolling mill
You are a supervised rolling mill trainee who only checks work orders, thickness, and anomaly records and does not give real roll gap or speed recommendations.
A1｜The work order requires 0.8 millimeter plate, while the on-site label says 0.8 centimeter, a unit conflict.
A2｜The thickness gauge calibration date has expired, but the system still shows "acceptable".
A3｜After the roll change the guide setup was not re-verified; the first piece continuously drifts and has surface scratches.
A4｜A jam occurs on the equipment, and someone on site asks to open the guarding and keep feeding.
A5｜The trainee only records, stops, and reports; machine adjustment, repair, and return to service are decided by authorized personnel.
Task one: mark items that cannot be released
List A1 unit conflict, A2 measurement reliability, A3 guide and surface defects, and A4 jam and guarding issues; write the status as "stop and isolate".
Do not estimate real roll gap, speed, or ways to bypass guarding.
Task two: write the review and handover
Make a checklist by problem, original work order, equipment status, batch, responsible person, and evidence pending.
Request verification of units, calibration, guide setup, and energy isolation status.
Record reported, retested, and approved-for-return-to-service separately.
Safety boundaries
The practice lacks real equipment and safety parameters, so no operating instructions can be derived.
Work order and unit card
Mark the A1 conflict between millimeters and centimeters, and stop production against that work order.
Others can see the unresolved specification problem.
Thickness and equipment card
Place A2 expired calibration and A3 the post-roll-change guides and first-piece defects side by side.
Do not treat a system "acceptable" as valid measurement.
Jam stop card
List A4 the risk of opening the guarding and the isolation status to be confirmed.
Do not write a stopped machine as approved for return to service.
Handover and approval chain
Record A5 who can review and who can approve return to service and product release.
Status must be clear to a person and a time.
| Stage | What may be assessed | Observed evidence | Use boundaries |
|---|---|---|---|
| Work order verification | What to do when 0.8 millimeters conflicts with 0.8 centimeters | Able to propose stopping and rechecking the original specifications | An interview question does not grant machine adjustment authority |
| Measurement verification | What to do when calibration has expired but the system reports acceptable | Able to isolate the result and recheck the instrument | Does not guess which measurement is correct |
| Jam handling | Whether the guarding can be opened to keep feeding after a jam | Able to propose stopping and authorized energy isolation | Cannot demonstrate real dangerous actions |
| Handover review | How to explain an out-of-tolerance batch and the return-to-service status | Able to clearly state the batch, responsible person, and evidence pending | A single practice does not predict long-term performance |
Day one
Read A1, mark the unit conflict, and write the reason for stopping.
Day two
Read A2, and compare the thickness gauge calibration with the sample records.
Day three
Read A3 and A4, and list the guide anomaly, jam, and guarding risks.
Day four
Read A4, and list the conditions that the empty-yard demo cannot be extrapolated to.
Day five
Following A1—A5, write the review and approval chain, keeping the status as pause scenario expansion.
Day six
Ask someone familiar with system verification to review the simulated materials, and record their comments.
Day seven
Keep the first draft and the revised draft, and review omissions and reproduction quality.

| Energy isolation training | People handling jams or equipment faults | Understand the shutdown, isolation, and return-to-service chain | Verify by equipment and region | Verify employer safety procedures | Requires refresher training | General operating authority does not include repair |
| Continuing education or certificates | People with a target skill certificate | Add material, equipment, or quality knowledge | Not a unified practice license | Verify the issuing body and scope of application | Per course and refresher training | A certificate does not transfer return-to-service sign-off authority |
Practice anomaly locating only with fictional work orders, material batches, thickness, and jam logs, without connecting to a rolling mill; the practice does not constitute operating authorization.

The BLS 2025 national median annual wage cited by O*NET is 50,140 U.S. dollars, with P10 at 37,690 and P90 at 70,310 U.S. dollars; these are not individual or regional quotes.
This page has not yet obtained a nationwide precise occupational wage distribution for rolling machine operators in mainland China. The National Bureau of Statistics 2025 pre-tax annual average manufacturing wages are 113,594 yuan for urban non-private units and 76,055 yuan for private units; the figure for "production, manufacturing, and related personnel" at above-designated-size enterprises in that industry is 79,182 yuan. These industry and broad-job references cover different populations and are not this occupation's wages, median, or starting pay, and cannot be assembled into an income range or attributed to AI. Metal and plastic rolling machine setup, tending, thickness measurement, and quality records correspond to the manufacturing scenario; the broad production and manufacturing category cannot distinguish rolling operators, materials, or shifts. Specific quotes must verify city, duties, working hours, contract term, base pay, and allowances／commission, and pre-tax versus after-tax.
BLS projects 51-4023 employment declining 8.3% over 2025—2035, with about 1,900 annual openings, mainly including replacement; openings do not equal new positions.
There is no reliable AI substitution rate for this occupation. AI can assist with work orders and anomaly summaries, while roll setup, measured dimensions, jams, and personnel safety are still verified by people.
Stop per procedure and escalate for jams, out-of-tolerance thickness, mismatched material, roll anomalies, guarding failure, or personnel approaching the danger zone.
Use only fictional work orders, material batches, roll gap, and thickness logs to practice specification conflicts and stop-work handover; do not connect to a real rolling mill.
You can explore extrusion, forging, maintenance, or manufacturing engineering, but you must add the target equipment, training, and duty evidence, and cannot transfer positions automatically based on rolling mill experience.
AI can assist with work order organization, anomaly summaries, and record drafts; rolling mill condition, material batches, measured dimensions, guarding, and return to service are verified by authorized personnel.
Occupational tasks follow this page's O*NET and related BLS occupational materials; U.S. wages keep the original precise or clearly parent-category／combined basis, and employment trends use the BLS 2025—2035 projection.
