Starting points only, copied from the makers' own published data. Every machine differs: test in scrap, tune by ear. Neither ChipLoad nor the makers are responsible for broken tools.
Published values, summarized per material and machine class. For the full CAM library (plunge, depth, stepover), download it from the maker.
| Material | Machine class | RPM | Feed IPM | Chip load (in) | Note | Source |
|---|---|---|---|---|---|---|
| Plastic, Acrylic, Plexiglas | industrial | 18000 | 25.0 – 30.0 | 0.00037 – 0.00045 | ⚠ Manufacturer chart range at 18,000 RPM, depth of cut 1xD (reduce feed 25% at 2xD, 50% at 3xD). Page 2. CHART INCONSISTENCY: the printed feed does not match RPM x flutes x chip load (25 IPM vs 27 from chip load; 30 IPM vs 32 from chip load). Transcription re-checked against the PDF. Trust the chip load and recompute feed, or ask Amana. | Amana Tool |
| Wood, MDF, Sign-Foam | industrial | 18000 | 35.0 – 45.0 | 0.0005 – 0.00065 | Manufacturer chart range at 18,000 RPM, depth of cut 1xD (reduce feed 25% at 2xD, 50% at 3xD). Page 2. | Amana Tool |
