How 4man works

Your own AI agent. Built around your shop.

4man learns your tooling, your machines, your materials, and your jobs. It reads manufacturer catalogs, forum consensus, and your own shop data — and gets sharper every time you ask.

01 · REMEMBERS YOUR SHOP

It knows what's in your crib.

Every conversation adds to a shop profile — tooling, machines, materials. Next time you ask about 4140 HRS, it already knows you run a Haas VF-2 with flood coolant.

What's my usual feed on 4140 HRS in the VF-2?
SFM 450 · RPM 3,440 · 41 ipm · per your May 12 run.
02 · CITES SOURCES

It shows its work.

Every spec comes with a source — Kennametal catalog, Sandvik training material, Machinery's Handbook, or a named forum thread. Tell it the number looks wrong and it'll recheck.

Source for IPT 0.003 on stainless finish?
Kennametal KCP25B catalog · p. 124 · finish pass range 0.002–0.004.
03 · WORKS THE QUOTE

It runs the numbers with you.

Drop a print. 4man runs cycle time, tool cost, and a cost-per-part roll-up against your machine rate and operator loading. You decide what to quote.

Cost per hole on 200× 0.201" through 304 SS 1.5" deep?
$0.187/hole · 3.2s cycle · $0.04 tool amort · $37.40 total.
