4- and 5-Axis CNC Machining for Complex Parts

How complexity is evaluated

Inaccessible surfaces, workholding orientations, second-operation needs, relationships between surfaces and inspection requirements are part of the technical review.

Multi-axis milling capacity

Simultaneous 5-axis machining handles parts up to Ø600 × 500 mm. 4+1 axis indexing on machining centres handles parts up to 1200 × 800 mm.

Advantages of multi-task machining

Multi-task turning and milling machining allows both turning and milling operations to be completed in the same setup. This eliminates multiple-workholding errors and improves positional tolerances between surfaces. For complex-geometry parts it reduces total production time and the number of setups.

However, multi-task machining is not suitable for every part. Simple rotational components can be produced more economically on a standard CNC lathe. The appropriate route is determined from the drawing review.

Part characteristics suited to multi-axis machining

The following characteristics indicate that a part may benefit from multi-axis or multi-task machining:

• ✓Complex components requiring both turning and milling operations
• ✓Long or thin-section parts difficult to hold consistently across multiple setups
• ✓Components requiring precise positioning between surfaces (axial holes, slot-bore relationships)
• ✓Parts with angled features requiring C, Y or B-axis capability
