MRR & Cutting Power — Acetal (Delrin)
Material removal rate and spindle power for milling Acetal (Delrin) using its specific cutting force kc.
Plastics barely register on the load meter (kc ≈ 200–400 N/mm²). The real constraint is melt temperature — if MRR climbs but chips fuse, drop spindle speed and keep the feed.
Formula
Note: Catalog starting values only — always confirm against your tool maker's data sheet and cut a test part. Machine rigidity, coolant and workholding shift real-world numbers.

About MRR & Cutting Power — Acetal (Delrin)
MRR & Cutting Power — Acetal (Delrin) computes the governing relationship Q = ap·ae·vf / 1000 · Pc = Q·kc / 60,000 live as you type. Plastics barely register on the load meter (kc ≈ 200–400 N/mm²). The real constraint is melt temperature — if MRR climbs but chips fuse, drop spindle speed and keep the feed. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use MRR & Cutting Power — Acetal (Delrin)
- 1Enter your values — Axial depth ap, Radial width ae, Table feed vf, Specific cutting force kc and more (sensible defaults are pre-filled).
- 2Read the live results: Removal rate, Power at cutter, Motor power needed.
- 3Check the "with your numbers" line to see Q = ap·ae·vf / 1000 · Pc = Q·kc / 60,000 substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use MRR & Cutting Power — Acetal (Delrin)?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula Q = ap·ae·vf / 1000 · Pc = Q·kc / 60,000 with authoritative sources cited on the page (Sandvik Coromant — Milling formulas & definitions; Kalpakjian & Schmid, Manufacturing Engineering and Technology, 7th ed., ch. 21)
- ✓Plastics barely register on the load meter (kc ≈ 200–400 N/mm²).
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the mrr & cutting power — acetal (delrin) use?+
It evaluates Q = ap·ae·vf / 1000 · Pc = Q·kc / 60,000, exactly as published. Sources: Sandvik Coromant — Milling formulas & definitions; Kalpakjian & Schmid, Manufacturing Engineering and Technology, 7th ed., ch. 21. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
Plastics barely register on the load meter (kc ≈ 200–400 N/mm²). Catalog starting values only — always confirm against your tool maker's data sheet and cut a test part. Machine rigidity, coolant and workholding shift real-world numbers.
When is this calculator the right tool for the job?+
Material removal rate and spindle power for milling Acetal (Delrin) using its specific cutting force kc. A free cnc machining: speeds, feeds & tool wear tool. The real constraint is melt temperature — if MRR climbs but chips fuse, drop spindle speed and keep the feed. For neighbouring scenarios, the related tools below cover the same engine with different presets.
Does it support both metric and imperial units?+
Yes — the SI ⇄ Imperial toggle converts the values already in the fields, preserving the physical quantity, so you can flip mid-calculation without re-entering anything.
