Aluminum A-Frame - one shot

Aluminum A frames provide stability for wing components in commercial aircraft. Machined from 7074 or 6082 aluminum, these structural parts include complex radial wall features and require tight tolerances. The typical production approach uses two operations – one for each side – with the workpiece mounted on tombstone fixtures.

Our customers have expressed a desire to produce the component in one operation.

Reduction of this process to one operation on a 5-axis machine tool would increase throughput and optimize production of this high-volume, high-value part. However, the demanding features of this part and the high amounts of material removal required to produce it make it difficult to fixture and machine on multi-axis equipment. Additionally, a one-operation approach would reduce tooling use if the process can compensate for the size of reground tools.

Aluminium A-Frame component

In collaboration with trusted partners, Seco developed and demonstrated a one-operation approach that machines this part on a multi-axis machine tool with a single fixture and 5-axis compensation. The process adds sustainability, with the ability to regrind and reuse tools up to four times. Reduced cycle times and energy use also promote sustainable production. Automation and advanced programming make dynamic pocket milling and 5-axis wall finishing easy to accomplish with fewer tools. Simulation through digital twins provides proof of concept prior to the cut.

The ability to control cutting diameter for circumferential finishing enables this process to achieve repeatably accurate geometric tolerances. This is essential to meet part specifications and set up automated production for potential lights-out manufacturing.

Challenge 2: Produce A frame component with dynamic pocket milling and 5-axis wall finishing

Challenges:

Maintain tolerances on radial geometry of 5-axis wall features.
Increase production efficiency and accuracy.
Minimize human intervention in production.
Produce precise aircraft part with reground tooling.
Compensate automatically for size of reground tools through on-machine probing and CNC software.

The Seco Solutions:

In partnership with Siemens, 5-axis cutter compensation adds circumferential finishing with repeatably accurate tolerances, even with reground tools.
Siemens control system command "CUT3DCD" activates 5-axis cutter compensation in programming for accurate part geometries.
Tool reuse through up to three regrind cycles cuts costs and boosts sustainability.
Accurate measuring tools from partner Zoller keep tool usage consistent for automated processes.
Multi-tasking production in one operation reduces the manual intervention and error likely with multiple setups.
Leading Seco regrind capabilities ensure proper dimensionality of finishing tools for demanding application.
