5-axis aerospace machining adds two rotary axes to the X, Y and Z linear axes, so the cutter reaches five faces, or follows a contoured surface, in a single setup. AeroCNCParts, a machining division of DEK, uses it on non-engine parts whose features sit on several faces. Each part keeps one program, fixture and inspection plan from first article to repeat batches. Read why 5-axis matters in aerospace manufacturing.
Angled holes, side faces and pockets cut in one clamping: no datum is transferred from one fixture to the next.
Tilting the part or spindle reaches deep pockets with a stiffer tool: better wall control and pocket floor finish.
The process that produced the approved first article runs on every repeat batch, so results stay consistent.
Each setup removed on a titanium or aluminum plate part is one less chance to mis-locate expensive stock.
Inspection follows the datum scheme of your drawing.

Brackets with faces at compound angles, attach fittings and hinge blocks: see our structural brackets.
Mount blocks, sensor mounts, connector holders: bolt pattern, locating bore and reference face per GD&T.
Thin-wall avionics housings with EMI flanges and side cut-outs, cut in the same setup as the pocket.
Tray table hinges, cabin partition fittings and decorative bezels with blended cosmetic surfaces.
Lightweight brackets, frames and pocketed panels for UAV and eVTOL programs in stable production.
7075-T7351, 7050-T7451, 6061-T6 for structures, brackets, avionics housings; sequenced roughing limits thin-wall distortion.
Ti-6Al-4V for high-strength, lightweight brackets and fittings; rigid setup, short tools, high-pressure coolant.
17-4PH and 15-5PH for high-strength, corrosion-resistant mechanical parts, machined in the heat-treat condition on the drawing.
Inconel 718 (AMS 5662) and 625 for brackets and fittings exposed to heat; low cutting speeds control work hardening.
PEEK and Ultem (PEI) for insulating and low-load functional parts; sharp tools and light clamping avoid distortion.
3+2 suits angled holes and multi-face prismatic parts; simultaneous 5-axis cuts contoured surfaces. Single-face parts cost less on 3-axis CNC milling; mixed operations go to complex multi-process machining.
