Hard Skills" and "Soft Skills" required to maintain the high standards of a precision machine shop. You can use this for self-assessment, hiring, or performance reviews.
🛠️ Technical Mastery (The "Hard" Skills)
Metrology & Inspection
• [ ] Tool Selection: Matching tool resolution to part tolerance (e.g., using a Micrometer instead of a Caliper for tolerances < \pm 0.05\text{ mm}).
• [ ] CMM Literacy: Ability to interpret CMM reports and understand alignment strategies (3-2-1).
• [ ] Surface Finish: Understanding the impact of tool paths on R_a and R_z values.
• [ ] Calibration Management: Ensuring all floor gages are within their calibration window.
GD&T & Blueprint Reading
• [ ] Constraint Logic: Understanding how Datums (A, B, C) fix the part in 3D space.
• [ ] Modifier Application: Applying Maximum Material Condition (MMC) to calculate bonus tolerances.
• [ ] Profile Control: Using profile tolerances to control complex, non-linear shapes.
Data & Statistics
• [ ] Capability Indices: Monitoring C_{pk} to ensure processes aren't just "passing" but are centered and stable.
• [ ] Control Limits: Distinguishing between Specification Limits (what the customer wants) and Control Limits (what the machine is doing).
• [ ] MSA/Gage R&R: Proving that the measurement system is reliable and repeatable.
Machine maintenance - machine maintenance routine check list as per iso and machine guidance
Environment assurance - environmental and seafty check list as per iso and compliance
🧠 Strategic & Problem Solving (The "Soft" Skills)
Root Cause Analysis
• [ ] Structured Investigation: Moving beyond "operator error" to find systemic causes using 5-Whys or Fishbone diagrams.
• [ ] Risk Assessment: Identifying potential failure points in a new setup using PFMEA.
Communication & Culture
• [ ] Machinist Collaboration: Ability to deliver bad news (rejected parts) in a way that encourages "Total Quality" rather than defensiveness.
• [ ] Customer Liaison: Translating technical inspection data into clear, concise FAIR (First Article Inspection) or PPAP reports for the client.
📂 Documentation & Compliance
• [ ] Traceability: Ensuring every part can be traced back to a specific material heat lot and operator.
• [ ] Non-Conformance (NCR): Precise documentation of what went wrong, where it is held, and how it will be disposed of (Rework, Scrap, or Use-As-Is).
• [ ] Standard Operating Procedures (SOP): Writing clear work instructions for inspectors to ensure consistency across shifts.
ISO - documentation and implementing and training to juniors
AS standards- documentation and implementation and training to juniors
📂 supply and dispatch Documentation & Compliance
Final operation - De buring , cleaning, countering, taping, lubricanting, counting and packing
documents- check sheet, inspection reports, test reports, supply sheets update, dispatch records
Traceability: Ensuring every part can be traced back to a specific material heat lot and operator.
