CNC Programmer onboarding at a glance

Week one covers orientation, safety and shadowing. Days 1–30 build vocabulary and supervised practice on core procedures; days 31–60 move to independent work with competency sign-offs; days 61–90 focus on full productivity, cross-training and a credential plan.

Before day one

Confirm start date, schedule, pay and supervisor in writing
Verify required credentials: NIMS CNC credentials, Mastercam certification (as applicable)
Prepare equipment and access: CAM software such as Mastercam, Fusion or Esprit; CAD software such as SolidWorks; CNC mills, lathes and multi-axis machines; machine simulation software
Assign a buddy or preceptor
Enroll the new hire in CNC Programmer training so foundations are covered before or during week one

Week one: orient and protect

Workplace tour, emergency procedures and incident reporting
Keep machine doors closed and guards in place
Simulate programs before running them
Wear eye protection on the shop floor
Follow lockout procedures when working in machines
Shadow an experienced CNC programmer through a full shift
Training modules 1–3: role foundations, a day on the job and essential vocabulary (15 terms)

Days 1–30: learn

Goal: perform core tasks safely under supervision.

Supervised practice: program a simple milled part in CAM
Supervised practice: prove out a new CNC program
Supervised practice: reduce cycle time safely
Training modules 4–7: duties, step-by-step tasks, tools and safety
30-day check-in: confidence, questions and early wins

Days 31–60: contribute

Goal: handle a regular workload independently.

Read drawings, models and GD&T callouts: independently
Plan machining operations and fixturing: independently
Create toolpaths in CAM software: independently
Select tools, feeds and speeds: independently
Competency sign-offs completed (see checklist below)
Training final knowledge check and certificate of completion
60-day check-in

Days 61–90: own

Goal: full productivity and a growth plan.

Meet productivity and quality targets for the role
Begin cross-training on a secondary task
Agree on a credential goal (for example, NIMS CNC credentials)
Discuss the career path: CNC Operator or Machinist → CNC Programmer → Senior Programmer or 5-Axis Specialist
90-day review
