Acrylic haze, fine swirl marks, white or stressed edges and rounded small features should be reviewed as separate observations. Select the matching rows to compare the source hypotheses and inspection checks. Record the incoming cutter-line condition and inspect the same region after a controlled trial. Keep edge appearance and critical dimensions visible rather than judging the part only by a general gloss impression.
Select the entries relevant to your review.
Possible causes are hypotheses; source adjustments are conditional review directions, not approved settings or confirmed diagnosis. Check feature access and media lodging on representative parts; chemistry and operating limits require supplied guidance. Keep every selected requirement with the part and the actual trial record. Selecting a row does not show that its acceptance condition has been met.
The source calls for checks of hard-particle contamination, edge temperature and critical dimensions. Confirm the actual acrylic grade and supplied process limits before changing conditions. No speed, temperature, cycle time, translucency target or final-media recipe is selected automatically by this tool.
Likely Cause: Tool marks are too deep, media is too coarse, or polishing time is not matched to the previous step
What to Check: Inspect an unfinished part under side light and compare cutter line depth before and after finishing
Recommended Adjustment: Add a controlled pre-smoothing stage, then use finer media for the final gloss stage
Likely Cause: Media or dry polishing material is contaminated with hard particles
What to Check: Check whether the machine bowl, media, separator, and storage bin contain metal chips or coarse abrasive dust
Recommended Adjustment: Clean the machine, separate acrylic media from metal media, and refresh compound or dry finishing material
Likely Cause: Excessive friction heat, aggressive media shape, or too much cycle time
What to Check: Check edge temperature, cycle length, and whether sharp media corners are striking the same area repeatedly
Recommended Adjustment: Shorten the cycle, reduce amplitude or speed, and test softer plastic or dry finishing media
Likely Cause: Over-processing or media too large for delicate features
What to Check: Measure critical dimensions before and after each test cycle
Recommended Adjustment: Use shorter test increments and choose media that contacts the surface without wedging into details
