Page 11: Recommended Sequence Of Operations For Amc
3.1 Recommended Sequence of Operations for AMC 3.1.1 Recommendations 1. When teaching the motions, be sure that the AOV is positioned perpendicular to the working surfaces for each media change module. 2. Consider a method of discarding used discs removed by the Media Remover. A recommended option is to mount the Remover in a way so that the used discs will drop into a collection bin after the removal process. - Page 12 Manual, AOV Media Changer System Document #9610-50-1046-02 The closest edge of the backing pad should be ½” to 1” away from the alignment rail. Figure 3.3—Away 2 5. TOUCH: Move diagonally (from the “AWAY” position in step 4) so that the backing pad is lightly pressed against the rail, pushing the sander’s orbital position away from the rail.
- Page 13 Manual, AOV Media Changer System Document #9610-50-1046-02 7. ALIGN: Align the sander with respect to the hole with the sanding discs. Confirm that the orbit is set fully back (6 o’clock position) before saving this point. b. Reliability can be improved for fetching by tilting the sander slightly (20 degrees) toward...
- Page 14 Manual, AOV Media Changer System Document #9610-50-1046-02 9. ALIGN and DROP: Pull the pad out of the feeder and return to the “ALIGN” position from step 6. Tilt the sanding pad and repeat step 7. This step helps to ensure the disc is properly attached as well as keep the stack of new media held down for the next fetch command.

Manual, AOV Media Changer System Document #9610-50-1046-02 3.1.3 Check Media Teaching this process should be done without a sanding disc on the pad to test the hook and loop 1. Start at the HOME position. 2. ABOVE: Align the sanding pad above the Media Checker’s loop pad. - Page 16 Manual, AOV Media Changer System Document #9610-50-1046-02 3. TOUCH: Lower the sander until the backing pad makes full contact with the hook and loop. Figure 3.12—Touch 4. UP: Raise the sander until the Checker has reached its furthest extension. An audible cue (sound of the hook and loop separating) can be used to determine the furthest extension.

Manual, AOV Media Changer System Document #9610-50-1046-02 3.1.4 Sand • It is important to test the removal of a freshly used disc. The friction generated from normal sanding operation can cause the hook and loop to bind stronger than a manually applied sanding disc. - Page 18 Manual, AOV Media Changer System Document #9610-50-1046-02 4. TOUCH: Move the sander to make firm contact with the top plate and extend the needles (90 PSI). It is recommended to wait up to one second before the next motion command.

AWAY: Using Figure 3.8 as a reference, move the sander up 12.0 inches and 9° travel to the right (approximately 1.9 inches of lateral travel). Make sure to move far enough away from the needles so that the disc is completely removed (at least the distance of one and a half disc diameters). -
