Linear Guide Rails in 7-Axis Aerospace Milling Cells: Dynamic Stiffness

Dynamic stiffness begins with material pairing. A 45 mm wide rail may appear massive, yet finite-element topology optimization reveals that a hybrid steel-ceramic bearing block can deliver 320 N µm⁻¹ lateral stiffness at 74 % of the mass. The key is a maraging steel body (18 % Ni) that is vacuum-nitrided to 1 200 HV, then laser-clad with a 0.5 mm layer of silicon-nitride on the...
