Common Mistakes to Avoid
**1. Not specifying tolerances.** Tolerance capability is the primary measure of machinist skill level. **2. Omitting equipment models.** Specific CNC brands and models (Haas, Mazak, DMG Mori, Okuma) are ATS keywords and signal familiarity to hiring managers. **3. Listing duties without quality metrics.** First-article pass rates, scrap rates, and customer escape rates demonstrate actual capability [1]. **4. Ignoring programming capability.** G-code editing, CAM software proficiency, and setup reduction initiatives add significant value. **5. Not mentioning quality system experience.** ISO 9001, AS9100, ISO 13485, and NADCAP compliance experience is essential for aerospace and medical machining.

Frequently Asked Questions
What tolerances should I mention in my machinist summary?
Include your tightest achievable tolerance — this is the single most important signal of your skill level. ±0.001" is standard CNC work, ±0.0005" is precision, and ±0.0001" or tighter is high-precision/master level [1].
How important is CAM programming for a machinist resume?
CAM programming (Mastercam, NX, Fusion 360) significantly increases your value. Machinists who can program and operate command higher compensation and are eligible for more advanced positions [2].
Should I list every CNC machine model I have operated?
Include the most relevant and advanced machines. 5-axis machines, Swiss-type lathes, and wire EDM signal higher capability than basic 3-axis VMCs.
