AiVibe5-Axis Machining
5-axis machining uses three linear axes plus two rotary axes to orient the tool relative to the workpiece, either locked at fixed angles (3+2 positional machining) or moving all axes together (simultaneous 5-axis).
A 5-axis machine adds two rotary axes to X, Y and Z. Common configurations are table-table, with a trunnion that tilts and rotates the part, head-head, with a spindle head that tilts and swivels, and head-table combinations. In 3+2 or positional machining the rotary axes index to an angle and the cut uses three linear axes. In simultaneous 5-axis machining all axes move together so the tool can follow a freeform surface while keeping a controlled orientation.
5-axis machining is used for turbine blades, impellers, blisks, aerospace structures, moulds, dies and medical implants. Even for prismatic parts it reduces the number of setups, improves feature-to-feature accuracy and lets shorter, stiffer tools reach deep features by tilting the tool or part.
Results depend on accurate knowledge of the machine's kinematics, including the position of rotary axis centre lines, which must be calibrated and periodically checked. Tool centre point control in the CNC keeps the tool tip on the programmed path as rotary axes move. Collision risk is higher than in 3-axis work, so simulation of the posted program against an accurate machine model is standard practice, and toolpaths need care near kinematic singularities.
Key points
- Adds two rotary axes to the three linear axes
- 3+2 machining indexes the part; simultaneous 5-axis moves all axes together
- Reduces setups and lets shorter tools reach deep or angled features
- Requires calibrated kinematics and thorough collision simulation
