CNC drilling and boring centres run programs automatically once set up. The setup itself — selecting tooling, writing or editing programs, dialling in speeds and feeds for a new material or job — still requires an experienced machinist who understands metal removal physics. Here is what the research says about the drilling and boring machine tool setter profession in 2026, and what you can do about it.

Task Automation Risk
66%
of current drilling and boring machine tool setter tasks are automatable with existing AI tools
Drilling and boring machine tool setters operate CNC machining equipment that produces holes, bores, and internal features in metal and other materials — components for automotive, aerospace, medical devices, and industrial equipment. Modern CNC drilling and boring centres are highly automated: once a program is loaded and tooling is set, the machine executes the cycle without operator intervention. The 66% risk reflects how much of the production run is automatic — cycle monitoring, chip management for predictable operations, and basic inspection of repetitive parts are being absorbed by automated measurement systems and statistical process control. What remains human-dependent: setting up the machine for a new job — selecting drill and boring tool geometry, calculating starting feeds and speeds, writing or editing G-code programs for non-standard features; diagnosing when surface finish or dimensional accuracy is drifting from tolerance and identifying the cause (tool wear, thermal growth, fixturing movement); troubleshooting machined feature problems that require judgment about the interaction between cutting conditions, workpiece material, and fixturing; and handling the first-article inspection that qualifies a new job. Operators who develop CNC programming ability (Mastercam, Fanuc G-code), measurement skills (CMM interpretation, gauge use), and process knowledge (feeds/speeds, insert selection) are in significantly more durable positions than those operating machines in pure run mode. NIMS credentials and Mastercam training are the most portable professional qualifications in this sector.

AI-assisted toolpath optimisation within CAM software (Mastercam, Fusion 360) is reducing the time experienced programmers need to develop efficient programs. Tools like Sandvik's CoroPlus provide AI-guided starting parameters for insert selection and feeds/speeds. These improve the setup process but don't eliminate the need for a skilled operator to execute and verify it.
Lights-out machining — unattended CNC production overnight or through weekends — is expanding at shops with sufficient automation investment (robotic loading, automated gauging). This compresses the total operator hours needed per part but increases the premium on the skilled setup machinist who qualifies the job before lights-out operation. Entry-level run operators are at higher risk than setup-capable machinists.
Precision machined components manufacturing is not leaving the US and Europe — aerospace, medical, and defence components require domestic production under regulatory requirements. The machinist workforce is ageing with insufficient new entrants coming through apprenticeship programmes. NIMS-certified machinists with CNC programming ability and process knowledge are in structural labour shortage in manufacturing regions.
CNC machining has a clear skill ladder that separates operators at different automation risk levels. Operators who only run established CNC cycles (load parts, push cycle start, check output) face higher automation risk as robotic loading and automated gauging mature. Machinists who can set up, program, and troubleshoot CNC equipment are in genuine labour shortage in most manufacturing markets — the career is durable at the skilled end.
A CNC operator runs established programs — loading parts, monitoring cycles, and checking output against inspection criteria on known jobs. A setup machinist sets the machine up for a new job — selecting and installing tooling, loading or writing programs, adjusting offsets, running first-piece inspection, and qualifying the job for production. Setup machinists command significantly higher wages and face lower automation risk. NIMS Level 1 and 2 credentials mark the transition from operator to setup capability.
NIMS (National Institute for Metalworking Skills) credentials are the primary portable certification in US precision machining — Level 1 covers measurement, materials, and safety; Level 2 covers CNC setup and operations for turning and milling. Mastercam Certified User (MCU) certification demonstrates CNC programming proficiency. Many community colleges offer associate degrees in Precision Machining Technology that combine NIMS credentials with CAM software training in a two-year programme.
G-code is the programming language that CNC machines understand — commands that control tool position, feed rate, spindle speed, and coolant. Operators who can read G-code can diagnose program errors and make simple adjustments without waiting for a programmer. Operators who can write G-code (or use CAM software to generate it) have full setup capability and command the highest wages. Fanuc G-code is the most widely used dialect across CNC machining equipment globally.
