Starting points only, sourced from the manufacturers' own published data. Every machine differs: test in scrap, tune by ear. Neither ChipLoad nor the manufacturers 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 manufacturer.
| 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. ⚠ Outlier: ours 0.00041" vs median 0.00352" of 4 other manufacturer(s): Freud, High Country Tools, SpeTool, Vortex (-88%) ⚠ Formula check: published feed 25.0 IPM vs RPM×flutes×chip load = 26.6 IPM (-6%) | Amana Tool |
