MRR & Cutting Power — Aluminum 6061
Material removal rate and spindle power for milling Aluminum 6061 using its specific cutting force kc.
Aluminum's low specific cutting force (~700 N/mm²) means a 15 kW spindle can clear well over 1,000 cm³/min — which is why HSM aluminum roughing is usually spindle-RPM limited, not power limited.

About MRR & Cutting Power — Aluminum 6061
MRR & Cutting Power — Aluminum 6061 computes the governing relationship Q = ap·ae·vf / 1000 · Pc = Q·kc / 60,000 live as you type. Aluminum's low specific cutting force (~700 N/mm²) means a 15 kW spindle can clear well over 1,000 cm³/min — which is why HSM aluminum roughing is usually spindle-RPM limited, not power limited. 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 — Aluminum 6061
- 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 — Aluminum 6061?
- ✓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)
- ✓Aluminum's low specific cutting force (~700 N/mm²) means a 15 kW spindle can clear well over 1,000 cm³/min — which is why HSM aluminum roughing is usually spindle-RPM limited, not power limited.
- ✓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 — aluminum 6061 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?+
Aluminum's low specific cutting force (~700 N/mm²) means a 15 kW spindle can clear well over 1,000 cm³/min — which is why HSM aluminum roughing is usually spindle-RPM limited, not power limited. 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 Aluminum 6061 using its specific cutting force kc. A free cnc machining: speeds, feeds & tool wear tool. Aluminum's low specific cutting force (~700 N/mm²) means a 15 kW spindle can clear well over 1,000 cm³/min — which is why HSM aluminum roughing is usually spindle-RPM limited, not power limited. 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.
