We reviewed the stage models. The first and second models conform to 
expectations but the the third needs work because its tooling 
requirements are more restrictive than the fourth stage.

We reviewed the tooling suggestions which are the following:

Tool1: DC=50mm RE=4mm cutter

1piece RAL90-050HA06-16H

4pieces KPHT 15 04 40 FR-CM H13A

(4 extra inserts are included as well.

Tool2: 1/2” solid drill (use collet your own collet chuck for this)

1piece 860.1-1270-038A1-NM H10F

Tool3: DC=20mm RE=2.5mm solid cutter (2 flutes)

1piece 930-HA06-HD-25-110

1piece 393.CGS-25 19.7 56

1piece 2S221-2000-250-NG H10F

Tool4: DC=16mm RE=2mm solid cutter (2 flutes)

1piece 930-HA06-HD-20-104

1piece 393.CGS-20 15.7 50

1piece 2S221-1600-200-NG H10F


We reviewed the fourth stage tolerances.  The tolerances were defined in 
CATIA and were transferred to STEP with a few exceptions. We agreed that 
the touch probe points shown on the model are for CMM verification only. 
Many fewer will be required for on machine verification.
