RPI supplies Rolls-Royce with five iMAPs to speed up engine manufacture and MRO

RPI UK, the world’s leading specialist developer and manufacturer of precision positioning devices for high accuracy rotary and angular inspection systems, has supplied five integrated measurement assembly platforms (iMAPs) to Rolls-Royce and its approved MRO facilities.

RPI’s iMAP, which is proven to reduce inspection times by 90% and improve gauge repeatability and reproducibility by up to 10 times, will be used by Rolls-Royce to measure and assemble engine turbine rotors at its sites in Derby and Germany.

Atlanta-based Delta Airlines, who carry out maintenance, repair and overhaul (MRO) of the Rolls-Royce Trent engine have also purchased a RPI iMAP machine – the first one sold to a Rolls Royce approved MRO facility.

Jim Palmer, RPI’s sales manager, said: “We’ve been working with Rolls-Royce for over 30 years so its great news that both Rolls-Royce, and their approved MRO facilities, are choosing to invest in IMAP which has been independently verified to give significant operational improvements over traditional measurement methods.

“With world-class accuracy, our iMAP machine achieve higher levels of quality by helping our customers understanding of their machining process capabilities as well as saving money and resources by significantly reducing inspection times and the need for costly rotor teardowns due to inefficient rotor assembly optimisation.”

iMAP’s data acquisition software AccuScan enables manufacturers to measure up to 4,000 data points on up to eight surfaces simultaneously per revolution thereby significantly reducing process times compared with other available method.

This significantly improved inspection data is then used by IntelliStack, iMAP’s Rotor Stacking Program, to solve the mathematical problem of how to best assemble a multi-stage rotor assembly to achieve minimum runout or unbalance of the finished rotor.

Specifically designed to inspect large and heavy components, RPI’s iMAP machines are fully compatible with any shop floor environment whilst maintaining world class accuracies more commonly seen in the standards laboratory.

Combining a motorised high precision air bearing rotary axis, rigid column unit, anti-vibration granite base and AccuScan multi-channel circular geometry inspection software, IMAP is the definitive system for productivity improvement in turbine rotor assembly.
