What Does a Machine Shop Supervisor Do?
Every work order that comes through the shop door, from a bracket needed by Friday to a full vacuum assembly, lands first with the machine shop supervisor. The supervisor decides which jobs run first, quotes the hours and materials and assigns work to the machinists, and no part leaves the shop until it has been checked against the drawing. Many of these shops serve research labs and engineering groups at universities and companies.

Machine Shop Supervisor Duties and Responsibilities
The primary responsibilities of a machine shop supervisor include:
- Log incoming work orders and set priorities with researchers, engineers and facilities staff.
- Quote jobs by estimating machine hours, materials and outside services such as plating.
- Assign jobs to machinists and instrument makers based on skill, machine time and deadlines.
- Check first-article parts and finished work against drawings before release.
- Order bar stock, sheet metal, cutting tools and fasteners within the shop budget.
- Run safety inspections, lockout-tagout checks and machine guarding reviews.
- Track shop hours and bill departments at approved recharge rates each month.
- Interview, hire and evaluate machinists, and plan training on new equipment.
- Arrange preventive maintenance and repairs for lathes, mills, grinders and saws.
- Machine urgent or difficult parts personally when the shop is short-handed.
Required Skills and Qualifications
To succeed as a machine shop supervisor, you will need the following skills and qualifications:
- Machinist background on lathes, mills and CNC
- Job costing and quoting
- Scheduling shop capacity
- Shop safety programs, including lockout-tagout
- Reading drawings and GD&T callouts
- Supervising skilled trades staff
- Fair, direct communication

Education and Training
Time at the lathe and mill, as a machinist or instrument maker, is the real qualification for running a shop, while BLS puts the typical education at a high school diploma. Some supervisors move over from running production in a factory. The job mixes machining with management, and experienced supervisors can become shop superintendents or instrument shop managers.

BLS projects employment of first-line supervisors of production and operating workers, the wider group that includes machine shop supervisors, to grow about 2 percent from 2025 to 2035. Progression is often slow in research shops and openings there are few, even though the group as a whole averages roughly 61,000 a year.
