BEIGAIN® ENGINEERING JOURNAL
Practical articles on CNC machining, materials, tolerances, inspection and procurement. Read the reasoning, compare the trade-offs, and bring the relevant details into your next drawing.
Materials
Select an aluminum alloy and temper around the limiting requirement. Higher yield strength does not automatically solve deflection, joining or cosmetic-finish problems.

Materials
The easiest stainless steel to machine may be unsuitable for the exposure or joining route. Evaluate the complete environment before trading corrosion performance for productivity.

Materials
Plastic parts can pass inspection immediately after machining and change later. A reliable specification connects material condition, cutting strategy and the environment in which the part must work.

Materials
POM, nylon and PEEK are not a simple good-better-best ladder. Select the grade that solves the dominant failure mechanism and then verify the complete operating condition.

Materials
Yellow color is not a brass specification. Alloy chemistry, temper, product form and service environment all influence whether a machined connector or fitting is suitable.
