Repeatable re-clamping for 5-axis aerospace components

An aerospace machining shop standardised multi-face set-ups so parts return to the same datum between operations.

01

The challenge

Structural parts are machined in several operations across 3-axis and 5-axis machines. Re-clamping between operations required re-probing and manual checks, and the shop needed location it could trust without adding inspection steps.

Tight clearance around the tool also limited how tall a fixture could be.

02

The solution

The shop adopted a Φ90 zero-point clamping module for its 5-axis tables and Pitch 52 plates on supporting fixtures. The 27 mm plate height leaves more working envelope under the part.

For multi-face jobs, a Three Face Pyramid special from the Custom Solutions range was specified so three sides of the part can be machined from one datum.

03

The results

Re-setup time between operations
60 → 12 min
Re-probing steps per changeover
4 → 1
Specified positioning accuracy of the INNGRIT interface
0.005 mm
