  What to put in, what to leave out

A resume for CNC machine work is read in a different order than most office resumes. The screener looks first for machine names and controls, then for tolerances you have held, then for years on each machine. If those three items are not visible in the top third of page one, the rest rarely gets read.

Start with contact details: name, city, phone, email, and a link to a portfolio or a short video of a setup if you have one. Skip the full street address and the photo. Add your shift availability and whether you can work weekends, because most machining floors run two or three shifts.

The professional summary runs two or three sentences. State your machine experience, the materials you cut most often, and the tolerance band you are comfortable with. One concrete line about setting up a 4th axis or proving out a first article carries more weight than a list of adjectives.

The technical skills block is where most applicants lose points. Group it by machine, by control, by CAD/CAM system, and by inspection tool. Write G-code and M-code rather than the word programming. Name the CAM post you have used, because a shop running Mastercam or NX wants that match confirmed on the first pass.

List materials you have actually cut. Aluminum 6061 and 7075, stainless 304 and 17-4PH, tool steel, titanium Ti-6Al-4V and plastics such as POM and PEEK are all worth naming, but only if you can talk about speeds, feeds and tool wear on them in an interview.

The experience section should quantify. Instead of writing that you ran a mill, write that you set up and ran three vertical mills, held ±0.005 mm on bearing bores, and kept scrap under the floor target. Numbers that describe your own output are safe. Numbers you cannot back up are not.

Most mid-size shops run applications through an applicant tracking system before a human sees them. The system matches literal strings from the job posting. If the posting says 5-axis and your resume says multi-axis, the match score drops. Use the employer's words, then add your own detail after them.

Write each skill line as a noun phrase with a number attached. Haas ST-20 lathe, 6 years. Fanuc control, setup and offsets. Mastercam 2023, 2D and 3D toolpaths. CMM inspection with PC-DMIS. That format scans fast and gives the reader something to ask about.

Avoid grouping unrelated items into one line. A line that reads quality, safety, teamwork and 5S tells the reader nothing about what you can run on Monday morning. Split it: 5S on your own cell, first-article inspection to an internal drawing, and daily machine checks with a log sheet.

Tolerance claims need a method behind them. If you write ±0.005 mm, be ready to say which machine, which fixture and which inspection tool got you there. A bore held on a 5-axis mill with a probe check is a different story from the same number claimed on a worn manual mill.

If you program, say which side of the process you own. Writing that you take a model, choose stock, set workholding, pick tools, post the code and prove it out on the machine describes a full setup-to-first-article loop. That is the sentence a shop owner remembers.

Keep the skills list to the machines and systems you would accept a job on. A resume that lists fourteen controls reads as a template. Four controls you know well, with years beside each, reads as a machinist.

A CNC operator listing screens for setup, offsets, tool changes, in-process checks and machine care. Lead the summary with the number of machines you can run at once and the tolerance you hold on a production run. Mention your fastest changeover and how you cut idle time.

A programmer listing screens for CAD/CAM systems, post processors, tool libraries and cycle-time work. Put the software in the summary line, not buried in a skills list. Describe one job where you reduced cycle time or replaced a three-operation setup with a single 5-axis operation, and give the before and after in plain numbers.

A CNC engineer listing screens for process design, fixture design, drawing review and root-cause work on scrap. Lead with the tolerance band you own across a family of parts and the inspection plan behind it. Mention GD&T on drawings and whether you write or approve the setup sheet.

A 5-axis specialist listing screens for simultaneous work, rotary tables, collision checking and post-processor tuning. Name the rotary table size you have worked with, for example a Ø400 mm table, and say whether you have run simultaneous or only 3+2 positional work. Be honest here, because the interview will find out.

One resume cannot serve all four. Keep a master file with every machine, material and number, then cut a one-page version per application. The cut takes fifteen minutes and changes the keyword match on the first screen.

If you are moving from a manual mill or a lathe into CNC, do not hide it. Manual experience explains why you can feel a bad cut and why you understand stock allowance. Put the manual work under experience, then put the CNC training or the machines you have run beside it.

Each bullet should answer three things: what you set up, what you held, and what the result was. A line like set up and ran a Haas VF-2 with a 4th axis, held ±0.01 mm on aluminum housings, ran 60 parts per shift does all three in one sentence.

Use the same unit system as the employer. A US shop wants ±0.0002 in in the bullet even if you think in millimeters. A European or Asian shop wants millimeters. Mixing units in one document looks careless, and the phone screen starts with a units question.

Describe inspection honestly. If you check with calipers and micrometers, say so. If you use a bore gauge, a height gauge, pin gauges or a CMM, name them. Shops that ship to automotive or medical customers care about the inspection chain, because their own records depend on it.

List the materials by name where you can. Aluminum 6061-T6, 7075, 304 stainless, 17-4PH, 4140, Ti-6Al-4V, Inconel and PEEK each behave differently at the spindle. A line that names three materials you have run for years beats a line that names twelve you have touched once.

Include machine care if you did it. Daily checks, way lube levels, coolant concentration, chip management and filter changes are the tasks that tell a foreman you will not wreck a spindle. They are also the tasks most applicants leave out.

For each job, note the part family if you can share it without breaking an NDA. Aerospace brackets, medical housings, EV busbars and robot arm joints describe the tolerance and finish world you worked in without naming a customer.

Certifications go below experience, not above it. A NIMS credential, a trade school certificate, a control-specific training course or an apprenticeship completion all carry weight because they are verifiable. List the issuer and the year beside each one.

Quality system knowledge is useful if you can describe your part in it. Saying you worked under ISO 9001:2015 or IATF 16949:2016 is fine when you can explain what it meant on the floor: first-article inspection, in-process checks, traceability, nonconformance reports. The certificate name alone adds little.

Safety training, forklift and overhead crane tickets, and first-aid certification belong in a short block. On a busy floor they decide who can move stock and who can cover a shift. Keep it to one or two lines.

Education should be short. Put the highest relevant credential first: apprenticeship, associate degree in machining technology, or a high school diploma with trade courses. Add the year only if it helps the reader place you.

If you have no formal certificate, replace that block with a training log. List the machines you have been signed off on, the controls you have learned, and the courses you have finished online. A dated log is more useful than an empty section.

Do not claim a certification you have not finished. Shops that serve aerospace or medical customers audit training records, and a claim that cannot be traced back to a certificate number ends the process.
