How Corner Radius Affects CNC Machining Cost
The same physics that makes internal corners impossible to cut square also makes corner radius a direct lever on cost — smaller radius, smaller tool, slower cut, higher price. Quick summary:...
ITAR vs. CMMC: What Defense Contractors Need to Know
ITAR and CMMC get treated as interchangeable in casual conversation, and they’re not. One governs who’s allowed to touch defense technical data. The other governs how securely you have to protect it...
When Does 5-Axis Machining Actually Save Money vs 3+2?
The sales pitch for 5-axis is that it does everything in one setup. That’s true. What the sales pitch doesn’t mention is that 5-axis programming takes longer, the machine costs more per hour, and a...
Why Does Every Aerospace Print Say ±0.001”? (And When You Actually Need It)
Open ten aerospace drawings and you’ll find ±0.001” on features that have no business needing it. That’s not because engineers are being careless — it’s because tight tolerance has become the safe...
ITAR Compliance for Machine Shops: What It Means for Your Parts
ITAR gets talked about as though it’s a certification you pass once and hang on the wall. It’s not. It’s a set of federal export control regulations that restrict who can access defense-related...
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...
