1. Introduction
The demand for complex machining is surging as industries like aerospace, medical, and automotive push the boundaries of innovation. Complex parts—defined by intricate geometries, multi-material compositions, and micron-level tolerances—require advanced manufacturing solutions. Traditional 3-axis CNC machines struggle with:
Geometric complexity: Undercuts, thin walls, and freeform surfaces (e.g., turbine blades with 0.2 mm wall thickness).
Material limitations: Machining titanium alloys and carbon fiber composites without delamination.
Cost inefficiency: Multiple setups increasing scrap rates by up to 15%.
5-axis CNC machining addresses these challenges by enabling simultaneous multi-angle toolpaths, reducing cycle times by 40% and achieving ±0.005 mm tolerances. For example, SpaceX uses 5-axis CNC to produce rocket engine nozzles with internal cooling channels, a feat impossible with conventional methods.
