5.2 CNC NESTED MACHINING

Considerations

  • Pre-Operation Checklist is a prerequisite for ANY operation.
  • Tool/Machine 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 completed in a timely manner.

Pre-Operation Checklist

Level 1

  • Inspects spoil board.
  • 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 free of cuts, tears and defects.
  • 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

  • Replaces/resurfaces spoil board when necessary.
  • Selects machine operation functions and options.
  • Selects and installs tooling to meet machining specifications.
  • Enters tool values into the tool database.
  • Inspects tooling apparatus for proper function.
  • Inspects and positions vacuum apparatus and support beams.
  • Meets Level 1 performance standard.

5.2.1 - Routing, Grooving And Boring

Level 1

Given a CNC nested base machine that is properly set up and adjusted, calibrated with the correct CNC tooling, and stock present, machine part(s).
Performance Standard
  • Dimension tolerance is within ±0.1 mm [0.004"].

Level 2

Given the CNC nested base machine, set up the machine and tooling, and machine part(s) to specifications.
Performance Standard
  • Verifies finished product measurements to design specifications.
  • Verifies tooling is processing within ±0.1 mm [0.004"].
  • Analyzes and corrects machining defects (quality of edges, holes).
  • Meets Level 1 performance standard.
