2.5 Straight-line Rip Saw

Considerations

  • Pre-Operation Checklist is a prerequisite for ANY operation.
  • Stock is fed in smooth continuous motion past blade with proper feed rate while controlling stock movement and waste removal.
  • Stock is supported at in-feed & out-feed.
  • Blade is completely stopped before clearing jammed materials.
  • Proper stance and hand position are demonstrated.
  • Stock is held securely against the fence (when utilized).
  • Required OSHA approved personal protective equipment is worn.
  • Operator is aware of work zone and safety precautions to others.
  • Correct body posture utilized during machine operation.
  • Operate machine safely, standing clear of kickback zone.
  • Material properly staged at in feed & out-feed.
  • Clears machine and cleans work area after operation.
  • Lock-out/Tag-out procedure is in place and followed.
  • Criteria/Performance standard requirements will apply to all operations, unless otherwise noted.
  • Material is suitable for its intended purpose and checked prior to sawing for warp, defects and foreign objects.
  • Initial trimmed cut edge is evident on entire length of material and exhibits smooth uniform saw marks with minimal burning and no back cut heeling.
  • Trimmed edges are straight and parallel.
  • Process is completed in a timely manner.

Pre-Operation Checklist

Level 1

  • Verifies tool is properly guarded and covered.
  • Verifies saw set up using a test piece.
  • Demonstrates knowledge of and proper use of all machine specific controls.
  • Ensures Anti-Kickback fingers are free of debris and functioning properly.
  • Ensures chain oiler (if equipped) is functioning properly.
  • Verifies dust collection operable/operating.

Level 2

  • Selects and properly installs correct blade.
  • Verifies Chain Groove Insert is intact to prevent fall off from binding
  • Calibrate fence (and laser - if equipped) for alignment with blade
  • Sets fence properly (dimension, parallel to blade and track, properly locked down).
  • Meets Level 1 performance standard.

2.5.1 - Rip multiple (3 or more) solid stock blanks to a specified width >100 mm [4"] using the fence.

Level 1

Given material of uniform thickness with one straight edge, and machine set up and ready to cut, rip material to specified width using a rip fence.
  • Leading stock is oriented correctly with respect to cup and bow
  • Tailing blanks are sawn two edges, of specified width. Dimension tolerance of +0.4 mm/-0 (1/64"/-0) [0.0156"/-0] in width along entire length of material.
  • Edge is straight to within ±0.4 mm (1/64") [0.0156"] in width (over 8' length) along entire length of material
  • Angle of cut is 90º to the face.
  • No defects caused by edges not being parallel are apparent.
  • Cut surfaces exhibit uniform saw marks with minimal burn marks.

Level 2
