MSP eliminates scrap for manufacturer machining rib components

Products used

Before

A Tier One supplier for aerospace parts came to MSP with a problem they were having when machining the rib component of the Airbus A330 wings.

The supplier had scrapped several parts due to not being able to accurately locate them during three separate machining cycles.

Their method involved fitting dowels in each end of a gun–drilled bore that went right through the part. The part needed to be rotated from end-to-end on the machine, aligning the two bores using a DTI. They then had to manually adjust the parts position until they aligned it correctly.

This process was very time consuming and not particularly accurate.

After

MSP knew NC-PartLocator from their MSP PerfectPart suite of products could create an alignment quickly and accurately, by probing a sphere at each end of the bore.

This method worked very effectively and MSP were able to setup the machining programs to run the probing cycles automatically during the machining.

NC-PartLocator was used for several functions in the machining process:

• Part alignment
• Alignment verification
• Bore size and position inspection
• Surface offsets for machining
• Re-alignment during post clamping changes

The project was a success and parts were coming off the machine and passing inspection well within tolerance. MSP also used their NC-Checker product to show the machine tool was working accurately, therefore giving MSP’s customer total confidence in its performance.
