Description
Key Responsibilities
-
Machine Setup & Operation
-
Setup, adjust, and operate 3-axis, 4-axis, or 5-axis DMG MORI CNC milling and turning machines .
-
Load raw materials, install fixtures, dial in work offsets, and set up cutting tooling (end mills, drills, taps, inserts, etc.).
-
Perform dry runs, single-block execution, and first-piece inspections to verify setup before full production runs.
-
Programming & Control
-
Read, interpret, and edit Siemens Sinumerik programs directly at the controller using G-code/M-code or conversational programming ( ShopMill / ShopTurn ).
-
Make parameter adjustments, tool length offsets, cutter compensation, and feed/speed tweaks as needed.
-
Quality Control & Inspection
-
Read and interpret complex engineering blueprints, drawings, and GD&T (Geometric Dimensioning and Tolerancing) callouts.
-
Inspect finished parts using precision measuring instruments including micrometers, calipers, height gauges, bore gauges, and CMM outputs.
-
Ensure components consistently meet tight tolerances (e.g., $\pm 0.0005''$ / $\pm 0.01 \text{ mm}$).
-
Maintenance & Troubleshooting
-
Conduct daily and weekly preventive maintenance on DMG MORI machines (coolant levels, lubrication system, chip conveyor, spindle check).
-
Diagnose operational issues, tool wear, and chatter; make real-time adjustments to cutting parameters.
