Why are you paying more 30-50% for your parts than you should?

In many projects, when costs start to increase, the first reaction is to question the supplier or the machining process. In reality, most of the time the cost is already defined much earlier, when the part is designed.

The CAM model silently fixes a large portion of the final price. Over and over again, the same patterns show up:  tight tolerance everywhere “just in case”, sharp internal corners that force smal tools, deep pocket with high length-to-diameter ratios.  None of these choices improve functionality.

All of them increase machining time, tool wear, setup complexity and risk. That's why cost grows. You're often not paying for better material or higher precision. You’re paying for time when the tool is not cutting efficiently.

What surprises many teams is how big the impact can be. As shown below, Two geometries that look nearly identical  can easily differ in cost by 30–50%, simply because one respects the manufacturing process and the other doesn't.

Machining itself isn't inherently expensive. The design decisions make it expensive!

This is why Design for Manufacturing isn't about “cutting corners” or lowering quality. It's about making conscious engineering choices early, when changes are still cheap and effective.

When geometry and tolerances are defined with process in mind, cost come down naturally, without compromising performance and reliability.
