CNC machining tolerances guide
CNC Machining Tolerances Explained: What's Achievable and What Costs Extra
Tolerance is one of the most consequential decisions in part design - yet it is often set by habit rather than analysis. We explain what CNC machining tolerances mean, what ranges are realistic, and why tightening a tolerance by 0.01 mm can double the cost of a feature.
Aluminium alloy selection for CNC machined parts
Aluminium Alloy Selection for CNC Machined Parts: 6061, 7075 and 2024 Compared
Not all aluminium alloys behave the same way in the machine or in service. A practical comparison of 6061, 7075 and 2024 covering strength, machinability, corrosion resistance and anodising quality.
Powder metallurgy vs CNC machining comparison
Powder Metallurgy vs CNC Machining: How to Choose the Right Process for Your Part
Choosing the wrong process at the design stage can result in parts that cost five times more than necessary. A practical guide comparing both processes on cost, volume, geometry and tolerance.
