Feed Rate & Chip Load — Stainless 304
Table feed vf = n·z·fz for milling Stainless 304, preset with a handbook chip load per tooth.
The cardinal rule in 304: keep the chip thick enough to get under the work-hardened skin from the previous tooth. Halving chip load in stainless shortens tool life instead of extending it.
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.
Table feed vf = n·z·fz for milling Stainless 304, preset with a handbook chip load per tooth. A free cnc machining: speeds, feeds & tool wear tool — no sign-up, no upload, instant results in your browser.
About Feed Rate & Chip Load — Stainless 304
Feed Rate & Chip Load — Stainless 304 computes the governing relationship vf = n·z·fz live as you type. The cardinal rule in 304: keep the chip thick enough to get under the work-hardened skin from the previous tooth. Halving chip load in stainless shortens tool life instead of extending it. 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 Feed Rate & Chip Load — Stainless 304
- 1Enter your values — Spindle speed n, Number of flutes z, Chip load fz (sensible defaults are pre-filled).
- 2Read the live results: Table feed, Feed per rev.
- 3Check the "with your numbers" line to see vf = n·z·fz substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Feed Rate & Chip Load — Stainless 304?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula vf = n·z·fz with authoritative sources cited on the page (Sandvik Coromant — Milling formulas & definitions; Machinery's Handbook, 31st ed. — Speeds and Feeds)
- ✓The cardinal rule in 304: keep the chip thick enough to get under the work-hardened skin from the previous tooth.
- ✓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 feed rate & chip load — stainless 304 use?+
It evaluates vf = n·z·fz, exactly as published. Sources: Sandvik Coromant — Milling formulas & definitions; Machinery's Handbook, 31st ed. — Speeds and Feeds. 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?+
The cardinal rule in 304: keep the chip thick enough to get under the work-hardened skin from the previous tooth. 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?+
Table feed vf = n·z·fz for milling Stainless 304, preset with a handbook chip load per tooth. A free cnc machining: speeds, feeds & tool wear tool. Halving chip load in stainless shortens tool life instead of extending it. 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.
