How to Read a CNC Quote: What’s Behind Each Line Item
Most CNC quotes arrive as a single number per part — unit price times quantity, done. That works fine for simple commercial jobs. Aerospace quotes are different. They may break the cost into line...
What Is an AS9102 First Article Inspection?
A First Article Inspection isn’t a quality-control formality — it’s the documented proof that a part, a process, and a drawing all agree with each other before production begins. Quick summary:...
What Is First Article Inspection and Why Does It Add Cost?
First article inspection is the reason your first aerospace production run costs more than every run after it. FAI per AS9102 is a complete dimensional verification of every single feature on the...
Waterjet vs Laser vs EDM for Aerospace Alloys: Which Process Fits Your Material and Thickness?
The right cutting process for an aerospace part depends on three things: the alloy, the thickness, and whether the cut surface is functional or just separating material. EDM belongs in the same...
MIL-A-8625 Anodizing for Machined Aerospace Parts: Type II vs Type III
If the drawing says “anodize per MIL-A-8625,” that’s not one process. It’s a family of processes, and picking the wrong type can mean a part that looks right but fails in service — or a part that...
Hybrid Manufacturing Machines You Can Actually Buy: What’s on the Market and What Do They Cost?
Every machine referenced in hybrid manufacturing research papers is commercially available. Shops are running them right now. The price range runs from under $200K for a retrofit kit on a Haas mill...
What Drives the Cost of Precision CNC Aerospace Parts?
The single biggest sticker shock in aerospace machining isn’t the material or the machine time. It’s everything around them — the compliance documentation, the first-article inspection, the material...
How to Specify Machining Allowances for SLM Hybrid Parts in Aerospace and Defense Applications
If you’re writing or reviewing a process plan for a hybrid-manufactured part — SLM-printed blank, CNC-finished to drawing — the machining allowance is the number that determines whether the finished...
