Learning and development process for Aerospace CNC Parts Makers: from loading operator to proving setter
Operators here take a long time to become setters because drawing, programme, tooling and inspection record must agree. A learning process with written steps makes the climb visible and faster.

Without a plan, learning is whatever the senior setter has time for. Operators load and unload well but call the setter for every offset and tool change, so one absence stops a machine. A new inspector learns the measuring equipment by watching, and picks up the senior's shortcuts along with the skill. Programmers keep hard jobs in their heads, and the shop cannot repeat a job when the programmer is away. Trainees are unsure what comes next and leave for places that tell them.
Good looks like a skill ladder with short sign-offs: own tool offsets, first-piece check, fixture set-up, proving a programme. Each step is watched on a real job by a named senior and signed. Inspectors have a similar path from simple to complex drawings. Programmers train an understudy per family of parts. The calendar includes time for learning, with recognition in the grade when a step is passed.
How to set it up
1. Write the ladder in steps a person can pass
From loading to offsets, tool change, first-piece check, fixture setting and proving. Each step names a task, a machine and a witness.
2. Assign a named senior for each trainee
One person per trainee, with a weekly ten-minute review of what was done and what is next. Free the senior from some output while teaching.
3. Sign off on real jobs
The senior signs when the person completes the step on a live part. Keep copies in the skills record.
4. Build an understudy for each hard job
Programmers document hard parts and train one person per family. Choose the understudy early, not in the notice period.
5. Teach the record as well as the cut
New joiners practise signed records on dummy jobs before live work. Link it to employee onboarding so habits start on day one.
Check these first
Before changing anything, find out what is true today. Use your own records for a defined period and note gaps in the evidence. The review may take longer if records are incomplete or spread across teams.
- Count how many operators can do their own tool offsets without calling a setter.
- List the jobs only one named programmer can prove and who is learning them.
- Ask each trainee what the next step on the ladder is and how long it should take.
- Check whether the last three new inspectors were signed off on a list or just told they were ready.
GullyHR can do this with you. Read how we approach learning and development process in general, or share your requirements and we will tell you where to start.
Questions owners ask
It depends on the machine and your parts, so avoid a fixed claim. Use sign-offs rather than a calendar date. Review progress monthly and adjust if people stall on a step.
Only after practice on cheaper material, because scrap hurts. Use proving runs on similar geometry in softer metal and let the senior supervise the first live part.
Both, for different steps. The setter teaches offsets and set-up, the programmer teaches proving and tool paths. Name each teacher in the ladder so nobody assumes someone else has done it.
We set up the interview and hiring process for aerospace CNC parts makers
Every business interviews, but few have a written process that works the same way for every role and every interviewer. GullyHR designs yours, from the role brief to the offer, trains your managers to run it, and can run it for you on the roles you hand us.
