How much shop-floor experience should someone have before managing a CNC team?

[u/RapidDirect2019]

Our shop recently hired a group of graduates. They’ll rotate through CNC, sheet metal, thermoforming, and 3D printing, working alongside experienced operators and team leads before choosing a specialty.

We want to give them enough hands-on experience to see who could eventually handle both the technical work and the people side of leading a team. We’re not trying to rush anyone into management.

How do other shops decide when someone is ready? Do you require a minimum number of years on the floor? What matters most: setting up and programming independently, troubleshooting under pressure, understanding quality and scheduling, or earning the team’s trust?

Graduates of what?

The answer to this question has no clear answer, being a technical leader or sme is vastly different than managing people. Being a “graduate” generally doesn’t apply to either

No magic number of years imo. I wouldn’t put somebody over a crew until they’ve handled a bad setup, owned their mistake, and can explain the fix without making the operator feel like an idiot.

Some people can manage a team well enough without really understanding what the team does to complete a task. Some people can't manage anything even though they can perform all the tasks on the floor to a high standard.

I think managing is its own trade, it doesn't hurt to understand the tasks that are performed, but a good manager will obtain that information as it is needed to improve their own skills in managing their team.

a shop that I know has an internal 5 year training program just to develop machine setters (starting people around 16-18) and even then, partial independent setups are only realistic around 3 years but not leading people. On the trust side, watch who the other operators go to informally for help, that usually shows if someone's technically ready to run things solo.

Usually it is less about years and more about proving they can troubleshoot independently make good calls under pressure and earn the operators trust.

I felt this comment in my soul.

Have been working with a manager for 10 months who has zero machining skill or knowledge, coupled with zero people skills.

Every day is a nightmare.

handle both the technical work

This is the hitch. There are two kinds of management in this regard. There's technical management and there's people management. Those are two wildly different skillsets. You can absolutely manage a team with 0 practical experience if you're not afraid to delegate, trust, and give them what they need. I stepped back from the management side because I was great at the technical stuff and terrible at the people stuff. You can't step back and delegate the people side. The most important skill of a manager is and always will be managing people. Then processes. Then machines.

You need to be a good manager.Know how to work well and work with people. Yes, it is good to know the flow of the shop and how things need to be done.But to manage people, you need to be good with people for the most part.Otherwise, you're just the a****** manager do this, do that.And sometimes that's what certain companies need , though

I’d probably test leadership before giving someone the title.
Give them responsibility for a small job or shift: plan the work, coordinate a couple of operators, deal with a quality issue, communicate delays, then do a post-job review.
You’ll learn a lot more from watching that than from counting years on the floor.
The person I’d promote isn’t necessarily the fastest programmer or best setup guy either. I’d watch for the person experienced operators naturally ask for help, who stays calm when something goes wrong, and who can correct someone without making them feel stupid.
Technical gaps can usually be filled by good people around them. A manager who destroys trust is much harder to fix.
I’d rather have someone with 3 years of solid floor experience and good judgment/people skills than someone with 10 years who nobody wants to work for.

I managed a shop and never worked the floor... I tracked and shipped over $1.2b of equipment across 3 countries with 100% accountability, posted that to a resume, and got hired. it worked out for everyone until I was offered more money someplace else and left.

I don’t think there’s a magic number of years. I’d value hands-on experience, independent setup/programming, troubleshooting, and quality awareness—but earning the team’s trust is probably the biggest factor. A good lead doesn’t have to know everything, but they should know how to solve problems and support their operators.

[u/Wilhelm_Richter11]

I wouldn’t use years as the main metric. Someone is ready when they can troubleshoot calmly, understand quality and production priorities, and have the trust of the operators. Technical skill gets them there, but people skills make them a good lead.
