4.11 Thru-Feed Double Shaper

Considerations

  • Pre-Operation Checklist is a prerequisite for ANY operation.
  • Stock is supported at out-feed.
  • Stock is fed in smooth continuous motion past tooling with proper feed rate while controlling stock movement and waste removal.
  • Proper stance and hand position are demonstrated.
  • Grain direction is correctly identified and appropriately considered for feed to minimize tear-out.
  • Demonstrate appropriate feed rate to control stock movement and waste removal relative to the size and type of material being shaped.
  • Stock is held securely against the fence, miter gauge, or fixture as appropriate.
  • Material is pushed completely past the tooling before releasing it.
  • Clears machine and cleans work area after operation.
  • 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 -
  • Verifies tool is properly guarded.
  • Demonstrates knowledge of and proper use of all machine specific controls.
  • Ensures paths of in-feed and out-feed have no obstructions to material and operator.
  • Verifies jigs and/or fixtures are secure and operating effectively.
  • Verifies hold-downs are positioned correctly at in-feed and out-feed for clearance to feed material.
  • Verifies dust collection is positioned and operating for effective chip removal.

Level 2

Performance Standard -
  • Verifies cutting tools are secure and free of defects
  • Installs cutting tool properly
  • Sets spindle rotation correctly
  • Sets spindle speed correctly
  • Verifies feed table is free of defects and clean
  • Verifies spindle height and/or angle are set to specified dimension(s)
  • Installs and properly adjusts required jigs and fixtures
  • Adjusts In-feed (and out-feed) to yield correct profile with smooth entry into and exit from part
  • Sets In-feed and out-feed control surfaces with appropriate clearance to cutter heads
  • Meets Level 1 performance standard

4.11.1 - Edge Shaping a Profile

Level 1

Given material, the machine set up and ready to cut, and a target edge profile, shape the edge of the material to the specified profile.
Performance Standard -
  • Loads material in fixture with appropriate edge and face towards cutter head and table surface
  • Shaped surfaces exhibit a uniform smoothness, with no burning or hesitation marks
  • Dimension tolerance is ±0.4 mm (1/64") [0.0156"] along entire length of material
  • Shaped surfaces are free of snipe
  • Shaped surfaces exhibit minimal tear-out
  • Shaped surface meets target profile
  • Profile is consistent along entire shaped surface, with no visible variation

Level 2

Given material, set up the machine and fixture to cut a target edge profile, shape the edge of the material to the specified profile.
Performance Standard -
  • Meets Level 1 performance standard

4.11.2 - Edge Shaping Curved Parts

Level 1

Given material, fixture, and machine set up and ready to cut, shape the edge(s) of curved material to a specified profile.
Performance Standard -
  • Loads material in fixture with appropriate edge and face towards cutter head and table surface
  • Shaped surfaces exhibit a uniform smoothness, with no burning or hesitation marks
  • Dimension tolerance is ±0.4 mm (1/64") [0.0156"] along entire length of material
  • Shaped surfaces are free of snipe
  • Shaped surfaces exhibit minimal tear-out
  • Shaped surface meets target profile
  • Profile is consistent along entire shaped surface, with no visible variation

Level 2

Given material and fixture, set up machine and shape the edge of curved material to a specified profile.
Performance Standard -
  • Meets Level 1 performance standard
