As with Press Tool Simulation, Stadco have recognised the benefits offered by Dimensional Variation Analysis (DVA) as part of a holistic approach to reducing development lead-times, driving out cost and continuing to meet and exceed quality targets.

By building a virtual assembly, applying theoretical tolerance bands and running simulated batch builds Stadco can quickly identify problems in the assembly process and address them before any physical parts are made.

From Stadco's position as both product developer and end manufacturer, we are well placed to integrate real world learning gained from our manufacturing assembly operations back into our product development activities. In particular, our ability to develop DVA modelling techniques to accurately reflect physical CMM inspection feedback has been critical.

Although most commonly applied during the product development process, DVA is also used at Stadco throughout the manufacturing cycle as an integral part of the continuous improvement process employed at Stadco.

During a recently delivered project based in India, Stadco's DVA activities resulted in fewer prototypes, improved root cause analysis and more robust corrective action plans from the prototype programme and a reduction in the number of product, fixture and tooling changes. This contributed to a faster ramp-up to high quality, volume production.

Stadco currently uses 3DCS software, and also has experience in the use of other commercially available DVA applications. If you have specific requirements, these can be discussed as part of our commitment to delivering customer satisfaction.
