What You'll Learn

Key competencies developed through this program

Auto-populatedfrom NSX Competency Framework

Mastery: developing (Level 2)(based on Certificate)

Vernier calipers, micrometers, and dial indicators — apply routinely and independently to calculate and verify dimensions and tolerances on completed parts in a mid-volume production environment.
Manual lathes, milling machines, and surface grinders — set up and operate with minimal oversight to machine parts to drawing specifications across a range of ferrous and non-ferrous materials.
Feed rate, spindle speed, and depth-of-cut parameters — monitor and adjust during active machining cycles to maintain surface finish and hold tolerances within ±0.001 inch.
CAM software such as Mastercam or Fusion 360 — generate or modify basic toolpaths for two- and three-axis CNC operations from existing CAD geometry in a production shop.
Sample parts and multi-view engineering drawings — study independently to determine operation sequences and fixturing requirements before setting up a new job.
CNC turning and machining centers — program conversational or G-code routines for familiar part families and verify dry-run execution before live cutting.
In-process quality checks — perform at defined inspection intervals using precision instruments to detect and flag deviations before they become nonconforming finished parts.
Machine tool preventive maintenance tasks including coolant checks, way lubrication, and filter replacement — complete on schedule to minimize unplanned downtime.
Troubleshooting common machining defects such as chatter, tool deflection, and poor surface finish — diagnose cause and apply corrective action using deductive reasoning and production experience.
Job travelers and ERP work-order records — update accurately after each operation to support accurate production tracking in a manufacturing facility.
