A CNC machinist with hands-on experience on both industrial and desktop platforms who sets up machines, runs parts, and inspects for quality.
What you would do
- Load CNC programs, install cutting tools, arrange work-holding fixtures, and establish tool offsets for production runs
- Run first-piece cycles and verify parts against engineering drawings and tolerance call-outs
- Perform machine maintenance and diagnose issues like tool wear, chatter, or dimensional drift during production
- Measure parts using calipers, micrometers, indicators, and CMM; validate compliance with specifications
- Collaborate with CAM programmers and engineers on setup strategies and manufacturability feedback
Who they want
- 5+ years hands-on CNC machining including both setup and production work required
- Required expertise with Haas VF-2 and comparable industrial CNC platforms
- Familiarity with hobbyist/desktop CNC machines (such as Makera Carvera or similar) strongly preferred
- Proficient in blueprint reading, GD&T interpretation, and advanced precision measurement tools
- Comfortable with diverse materials: metals, plastics, and composites; excellent written and verbal English
Main skills
What the interview asks about
1.Multi-platform program adaptation
A Haas program with 0.0005" tool offset often fails on desktop machines with different thermal stability and spindle runout tolerances.
For example: “You receive a Haas VF-2 program for a 0.500" hole with ±0.003" tolerance. The customer also needs the same part on a desktop machine with lower spindle accuracy. How do you adjust offsets, feeds, or speeds to maintain tolerance?”
2.First-article GD&T verification
Misreading a call-out-positional tolerance, runout, datum reference frame-leads to scrap runs; inspectors must catch before production.
For example: “A drawing shows a hole positional at 0.010" within datum A-B-C and uses three datums. You measure the hole location at 0.007" from the origin but 0.012" when you reference datum B directly. What does this tell you about part setup?”
3.Tool wear versus setup drift diagnosis
Operators who adjust only feed rate miss spindle runout or worn bearings; those who only compensate offset miss tool life.
For example: “After 30 parts, hole diameters drift from 0.500" to 0.498". Hole location stays stable. You've checked tool offset and it's correct. What's your next troubleshooting step and why?”
4.Hobbyist-to-industrial machine constraints
Desktop machines have backlash and thermal drift hobbyist operators need to account for in tight-tolerance runs.
For example: “A Makera Carvera produces a part to ±0.010" consistently, but the customer requires ±0.005". Is this a fixture design, feed/speed, or material choice problem? How would you determine this?”
5.Materialflow and cutter performance variation
Aluminum machines differently than stainless steel or acetal plastic; poor material selection leads to chatter or breakage.
For example: “Your program works on aluminum at 200 SFM but fails on 303 stainless steel at the same speed, producing chatter and tool breakage after two parts. Explain your adjustment strategy and the reasoning.”
A task you may get
Given a blueprint with GD&T call-outs, a program for a different machine, and your measurement data from the first part, diagnose a dimensional problem and document the setup changes needed to hold tolerance on the production run.
How to prepare
- Review a recent part you machined that had to be scrapped or reworked; document what the first-article inspection should have caught
- Compare a Haas and desktop CNC program for the same part; list which offsets and speeds would need adjustment and why
- Study two material data sheets (aluminum vs. stainless vs. plastic) and note how feeds, speeds, and tool geometry differ
