The JSC Electric machine building plant LEPSE (JSC LEPSE) manufactures aircraft electrical equipment that can be found in every Russian production aircraft.
Recently, the company realised it needed to enhance its competitiveness by improving quality and reducing production schedules.
After evaluating the market, it determined that the best approach to meet its needs would be to adopt product lifecycle management (PLM) technology from Siemens PLM Software. Solutions included Solid Edge software for new product and die mould development, NX software for computer-aided manufacturing and Teamcenter software for complete PLM.
JSC LEPSE was able to implement an enterprise-wide master model during the deployment of Solid Edge. The master model drove tooling design, NC programming machines and engineering evaluations. All required projections are generated based on 3D models.
“This approach enables our specialists to significantly improve the quality of their work,” says Dmitry Emelyanov, deputy head of the JSC LEPSE Information Technology Directorate. “Application of associative links significantly reduces the quantity of errors during design planning, design updates and modification development.”
Resources have been optimised too. “Developing a common product data bank and establishing a timely process for change management became vital, so we used Teamcenter to create a common information source,” says Emelyanov.
Teamcenter also enabled JSC LEPSE to standardise its process for filing engineering documents – some of which are held for many years.
The implementation of Teamcenter helped significantly improve the efficiency of JSC LEPSE’s allocation of manpower. The PLM environment enables teams of specialists, such as designers, process engineers, and NC machine programmers, to work on a project in parallel.
“While the designer is working with the assembly and making updates, the process engineer may already start the tooling design,” says Emelyanov. “At the same time, another specialist can prepare the NC programming. By adopting this concurrent process, we are able to minimise the need for corrective actions, such as updating complicated production tooling, and ensure improved product quality.”
Using Teamcenter also helped enable LEPSE plant management to consolidate their designers, process engineers and tooling department into one integrated team.
Meanwhile, the use of Solid Edge has enabled the replacement of 2D drawings with 3D models. The associative master model created by the designer became the basis for the concurrent sharing and operation of other departments. This approach reduced the preproduction period and substantially increased product quality due to fewer errors and tight project development.
