 Project Summary In summer 2003 CNES successfully tendered for the detail design engineering and manufacture of the prototype fabricated hull for ‘Terrier’, the new air-transportable armoured combat engineer vehicle. The fully-assembled and machined hull was delivered to the client in autumn 2004. Hull weight: 6.8 tonnes Dimensions: 6m x 2.5m x 2m End User: Royal Engineers Client: BAE Systems CNES Expertise
Project Details As with all its major projects, CNES brought together a multi-disciplined management team to drive the project forward. Work started with the production of engineering drawings for profiling, machining and assembling the armoured and mild steel plate, cast products and the manufacture of sub assemblies. CNES designed and built bespoke jigs and fixtures,including a 360° rotating jig, in order to meet the 5mm build tolerances specified. The hull comprised some 380 individual components, which had to be procured and then machined. In order for these to arrive in the right place, at the right time and in the right sequence, an electronic tracking system was developed and implemented to report on the status of all commodities throughout the manufacturing programme. This supports the 100% traceability of CNES’ ISO9001:2000 compliant quality management systems. The assembled hull was fully machined on a gantry mill and floor borer. The operations include face milling, boring, drilling and tapping to within ±0.05mm, with surface finishes ranging from 0.8Ra to 3.2Ra. The final inspection was carried out using Faro Laser Tracking and Faro Titanium arm portable coordinate measuring machines. | |
