Unlike an operator who runs one machine, this job means reading blueprints to plan the sequence, then securing stock in fixtures or chucks and selecting the right cutting tools for each machine before running it, checking finished workpieces against spec throughout. Because the equipment includes lathes, cutters, shears, borers, millers, grinders, presses, and drills, the work brings more day-to-day variety than a single-machine role, but it also means more setups and adjustments to get right on any given shift.
Pros
Over 12,800 positions nationwide, a fairly resilient niche compared to single-machine trades
No degree required, just a high school diploma and on-the-job training
Broader skill set than single-machine roles: setting up and running lathes, cutters, drills, and presses
Cons
Above-average hours, often more than a standard 40-hour week
Employment projected to shrink slightly over the next decade (-0.5%)
Fast-paced, deadline-driven work with real exposure to hazardous equipment
A typical day
This shop runs lean, so one operator owns three machines: the morning starts by loading a turning job on the lathe, and while it runs, setting up a surface grinder for a batch of hardened plates. The day is choreography — timing tool changes and part swaps across machines so none of them sits idle, ears tuned to each one's normal sound because a change in pitch means trouble before the alarm knows it. Mid-shift, a rush job bumps the queue and a mill gets torn down and re-set in forty minutes. Micrometer checks punctuate everything. By shift's end the operator has run four different part numbers on three machine types and logged every one.
Tasks at the job
Inspect workpieces for defects, and measure workpieces to determine accuracy of machine operation, using rules, templates, or other measuring instruments.
Position, adjust, and secure stock material or workpieces against stops, on arbors, or in chucks, fixtures, or automatic feeding mechanisms, manually or using hoists.
Read blueprints or job orders to determine product specifications and tooling instructions and to plan operational sequences.
Select, install, and adjust alignment of drills, cutters, dies, guides, and holding devices, using templates, measuring instruments, and hand tools.
Observe machine operation to detect workpiece defects or machine malfunctions, adjusting machines as necessary.
Set up and operate machines, such as lathes, cutters, shears, borers, millers, grinders, presses, drills, or auxiliary machines, to make metallic and plastic workpieces.
Workplace & working conditions
Work happens indoors in a climate-controlled setting, and most of the day is spent on your feet. The role involves regular exposure to hazardous equipment or conditions and contaminants, and standard protective equipment (gloves, safety glasses, and similar) is expected.
The pace is often fast, with real time pressure to meet deadlines. Precision and accuracy are essential to the work.
Education necessary or common
High school diploma; some on-the-job training or apprenticeship
