10.1 Screw Pocket Machine

Considerations

  • Pre-Operation Checklist is a prerequisite for ANY operation.
  • There are numerous types of machines and portable tools for creating pocket hole joinery. This standard is concerned with the execution and assembly of this joinery. Set-up and adjustments will differ by manufacturer.
  • 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.
  • Process is completed in a timely manner.

Pre-Operation Checklist

Level 1

Performance Standard-
  • Clears area around machine for unobstructed access.
  • Positions foot switch for ease of use.
  • Tests safety mechanism for proper operation.
  • Demonstrates proper holding of stock to prevent vertical or horizontal movement when engaging cutter/drill.
  • Verifies dust collection operable/operating (if equipped).
  • Clears excess dust buildup from machine if dust collection not present.

Level 2

Performance Standard-
  • Inspects hold-down for damage and proper operation.
  • Inspects for free unobstructed movement of cutting apparatus before power is applied.
  • Checks tooling and replaces/cleans if needed. .
  • Adjusts machine settings appropriate to the material thickness.
  • Meets Level 1 performance standard.

10.1.1 - 90º Pocket Screw Joint

Level 1

Given material and a machine set up, cut pockets and assemble a 90 degree joint.
Performance Standard-
  • Makes a joint face which is flush ±0.005"
  • Maximum gap of 0.001" in joint between opposing parts after assembly caused by screw pocket machining
  • Holes are more than 3 mm (1/8") [0.125"] away from any edge of stock being machined
  • Joint is located within ±0.4 mm (1/64") [0.0156"] of desired location

Level 2

Given material, set up machine to cut pockets and assemble a 90 degree joint.
  • Adjusts screw pocket position relative to edge (web distance) for length of screw being used
  • Adjusts pocket cutting feed rate for optimal cutting relative to material type and tool sharpness
  • Meets Level 1 performance standard

  • Joint is located within ±0.4 mm (1/64") [0.0156"] of desired location

Level 2

Given materials, set up machine or jig to execute pocket joints and assemble product.
Performance Standard -
  • Adjusts machine and tooling for proper depth of cut
  • Adjusts screw pocket position relative to edge (web distance) for length of screw being used
  • Adjusts pocket cutting feed rate for optimal cutting relative to material type and tool sharpness
  • Meets Level 1 performance standards
