Project Requirements
The front uprights connect the wheel hub, suspension, braking and steering systems.
Multiple mounting surfaces, precision bores and threaded holes had to maintain accurate positional relationships to support suspension alignment, steering response and reliable assembly.
Manufacturing Challenges
The components were machined from solid 7075-T6 aluminum billets and required extensive material removal.
The main challenges included:
• Multi-surface positional accuracy
• Precision bores and threaded holes
• Lightweight sections with deformation risk
• Controlled relationships between suspension interfaces
• Reliable inspection of critical features
5-Axis Machining Strategy
The uprights were produced using a 5-axis CNC machining strategy that provided access to multiple functional surfaces while reducing repeated repositioning.
High-speed roughing removed bulk material efficiently, while precision boring, deep-hole drilling, rigid tapping and controlled finishing were used for critical features.
