5.4 CNC Aggregate Head

Considerations

  • Tool/Machine/Aggregate Head Manufacturer's safety rules and guidelines are followed.
  • Panel support rails (if present) are used to assist with large panel movement and placement.
  • Tooling requirements are reviewed and appropriate tooling on the machine verified.
  • Operator does not reach into the machine processing area while the machine is in operation.
  • Stock is held securely.
  • Operator clears machine and cleans work area after use.
  • Required OSHA approved personal protective equipment is worn.
  • Lock-out/Tag-out procedure is in place and followed by everyone.
  • Process is completed in a timely manner.

Pre-Operation Checklist

Level 1

  • Activates vacuum system and assures stock is properly secured.
  • Verifies machine is properly guarded and safety mechanisms are in place and operating.
  • Demonstrates knowledge of and proper use of all machine specific controls.
  • Verifies vacuum pod gaskets or table surface gaskets are clean and free from defects.
  • Selects machine operation functions and options.
  • Inspects material for nails, staples or foreign materials before processing.
  • Verifies scrap and offal is removed from the machine prior to processing material.

Level 2

  • Selects and installs tooling to meet machining specifications.
  • Installs and adjusts vacuum pods, gaskets or fixtures as required.
  • Enters tool and aggregate values into the tool database.
  • Inspects aggregate head for proper tooling installation and function.
  • Check aggregate head for proper fit in C-axis and adjust arrester bolt as required.
  • Inspects and positions vacuum apparatus and support beams.
  • Checks lubrication system for proper levels and function.
  • Adjusts and modifies existing programs as necessary.
  • Sets program and performs dry run prior to production.
  • Conduct tests to determine internal wear on aggregate head.
  • Meets Level 1 performance standard.
