Wall Thickness and Ribs in CNC Milled Structural Parts
A structural part can look rigid on screen and still chatter, deflect, and drift out of tolerance on the machine. In CNC milling structural parts, wall thickness and rib layout decide whether the cutter stays stable or the part starts moving under it. The mistakes are predictable: a tall, thin web that nobody checked against its height, or a field of ribs added for stiffness that turns a one-setup part into a three-setup job. Below is how we approach wall thickness and rib de
