Safety rules for CNC & VMC machine operator during operating the machine | Skill Serve for ASVPL

Mandatory Safety Equipment (PPE) for CNC/VMC Operation
📌 Operators must use cotton hand gloves when handling components immediately after machining, as parts may be hot, preventing burns.
👟 Safety shoes with thick soles are essential to protect feet from injury caused by falling heavy objects on the shop floor.
👂 Earplugs must be worn in noisy shop environments created by CNC and VMC machines to protect hearing from excessive noise exposure.
👓 Safety goggles are required to shield eyes from metal chips and dust particles generated during the machining process.

Pre-Operation Machine Checkpoints
✅ Always check the machine according to a check-sheet before starting work to minimize accident chances.
🚨 Verify that the Emergency Stop switch is functioning correctly before beginning any operation.
🔧 Confirm that system pressure, including chuck pressure and clamping pressure, is within the specified green range.
💧 Check critical fluid levels, including hydraulic oil level and lubrication system oil level, ensuring they are within proper operational limits.

During Production and Quality Control
🔩 Clean the fixture thoroughly, removing chips and dust, before clamping the next forging or casting part securely.
🟢 The machine indicator lights signal status: Green for automatic operation, Yellow for operation completion, and Red for any alarms or problems.
📏 After operation, components must be cleaned and measured; OK parts go into the blue or green bin, rework parts into the yellow bin, and rejected parts into the red bin.
🏷️ Ensure all processed components are correctly tagged: OK tag for accepted parts, Hold tag for held material, and Reject tag for discarded parts.

Unsafe Actions to Avoid
🏃‍♂️ Avoid rushing for high production volume by increasing machine speed and feed rates, as this compromises safety.
🚫 Never wear loose clothing (untucked shirts, open sleeves) or have unsecured shoelaces while operating machinery, as these can get caught.
⌚ Do not wear any bracelets or watches near running machinery, as these items can get trapped, leading to accidents.
✋ Never place hands inside a running machine; wait until the entire operation is complete and the door is opened to remove the component.

Unsafe Conditions and Emergency Response
💡 Unsafe conditions include poor lighting, spilled oil or coolant on the shop floor, and ignoring damaged wires or pipes.
👨‍🔧 Only properly trained and certified individuals should be permitted to operate CNC and VMC machines to prevent accidents due to incomplete knowledge.
🏃‍♀️ In an emergency situation, all employees must exit via the designated exit points without causing a stampede and gather at the predetermined emergency assembly point.

Key Points & Insights
➡️ Adherence to proper PPE usage (gloves, shoes, goggles, earplugs) is fundamental for operator safety on the shop floor.
➡️ Performing thorough pre-operation checks—especially the E-stop and pressure readings—is crucial for machine integrity and accident prevention.
➡️ Maintaining a clean workspace (checking for spills and debris) and following strict protocols for part sorting (OK/Rework/Reject tagging) ensures quality and safety compliance.
