A 4-MINUTE STORY · ILLUSTRATION
Same sentence, three shops: why depth in one operation qualifies you
A generic capability line makes the best shop and the weakest look identical. Depth within a single operation is what qualifies you.
Which 5-axis, which features, which alloys, and how you know the part is right before it leaves the machine. Three invented shops publish the same line. Pick the work you want, then scroll. We'll read all three against one RFQ, the way a buyer at an engine-parts supplier would.

AS SAID · ONE SUPPLIER SEARCH
Three shops, one line.
Three machine shops turn up in the same supplier search. Their capability pages say the same thing, nearly word for word: 5-axis CNC, aerospace, Inconel. Each has a photo of a five-axis machine and a paragraph about quality.
The line answers the same few questions for every shop, and nothing else.

NEXT: THE READ ↓THE READ · RFQ 26-118
She reads each site against the notes.
A buyer at an engine-parts supplier has an Inconel 718 blisk to place. The drawing's note list asks what any blisk asks. Simultaneous 5-axis, or 3+2? Are the airfoils flank milled? Can you hold thin airfoil walls in a material that work-hardens and fights the tool? Do you probe in process, or find out at the CMM? She reads each site against the notes, and every column fills with question marks.

The RFQ goes to all three.
On paper the three shops are the same shop. So the RFQ goes to all three and price decides, or it goes to a name the buyer already knows. The shop best fitted for the part gets no credit for the work it does best.

NEXT: AS BUILT ↓AS BUILT · ON THE FLOOR
On the floor, nothing alike.
On the floor they are nothing alike. One runs simultaneous 5-axis with CAM set up for flank milling, probes the airfoils in process and has cut Inconel 718 rotating parts for years. One runs 3+2 well and finishes airfoils with point milling. One has cut Inconel brackets on a trunnion table.
Scored against the full seventeen-line list, they'd land at 16, 11 and 6. Nothing on any of the three sites shows it.

Write the depth down, one operation at a time.
The Buyers Blueprint, our paid onboarding, asks the questions a buyer's note list asks, one operation at a time: which 5-axis, which features, which alloys, what you inspect and when. In step 4, the website build puts each answer on the process page an engineer lands on.
IKE, our Industrial Knowledge Engine, already knows what buyers screen a 5-axis shop on, so the questions start there. Each answer keeps its source.

Same search. Now she can tell.
Same search, same three shops. The scores drop into the title blocks: 16, 11 and 6 of 17. The strongest shop's page now answers the note list line by line, and the buyer can see the difference before she writes the RFQ.

102 · THE LESSON
A generic line hides your depth.
A generic capability line makes the best shop and the weakest look identical. “5-axis CNC, aerospace, Inconel” fits a shop that cuts blisks and a shop that cuts brackets.
Depth within a single operation is what qualifies you: which 5-axis, which features, which alloys, and how you know the part is right before it leaves the machine.

General notes
- The shops, people, websites and figures in this story are invented to show a pattern we see often.
- Simultaneous 5-axis moves all five axes during the cut. 3+2 locks the two rotary axes at an angle, then cuts in three.
- A blisk is a bladed disk: the airfoils are machined from the same forging as the disk, so it has no blade roots.

YOUR TURN · THREE YES OR NO CHECKS
Check your own
Three yes/no checks you can run on your own site on Monday morning.
Does your site say which 5-axis?
Simultaneous 5-axis or 3+2, on which machines, with what envelope.
Does it name the features you cut?
Thin walls, airfoils, fir-tree roots, deep pockets, and in which materials.
Does it say how you know the part is right?
In-process probing, your first-article method, what you inspect and when.
