Guidelines and Trend Reports

Basic principles, design, DFM (Design for Metalworking), and summary of failure cases for copper electroplating of CNC parts Many products with high-power signal output utilize numerous CNC-machined parts with copper plating for conductivity and electromagnetic interference shielding. Therefore, the use of copper-plated CNC structural components in such products is not…

CNC machined aluminum heat sink design and DFM guidelines Many high-performance aluminum heatsinks fail because their designs ignore the limitations of CNC machining. Fin geometries that appear perfect in CFD simulations can actually cause tool chatter, part scrap, and extended lead times, disrupting the entire New Product Introduction (NPI) plan.…

CNC Machining of Parts with Minimum Wall Thickness and Related Part Design Guide Components with varying wall thicknesses are increasingly used in a wide range of products. Low-wall-thickness parts are lightweight, material-saving, and compact, while high-wall-thickness parts are the opposite. Thin-walled parts are extremely difficult to manufacture, and companies offering…

Machining Tolerance Guide: Tolerance Grades Achievable by Different CNC Equipment We deal with cnc machining every day. Do you know what precision tolerance grades can be achieved by turning, milling, planing, grinding, drilling, and boring? Tolerance grade refers to the level that determines the accuracy of a dimension. The national…

Comprehensive Guide to Surface Roughness of CNC Parts Surface roughness is one of the most useful reference tools for understanding the surface finish of CNC parts, comparing roughness values, and linking drawing requirements to actual manufacturing decisions. It helps engineers, purchasing personnel, and production teams interpret surface quality more clearly,…
