Large Additive Subtractive Integrated Modular Machine

General Information

The LASIMM project aim is to develop a large scale flexible hybrid additive/subtractive machine based on a modular architecture which is easily scalable. The machine will feature capabilities for additive manufacture, machining, cold-work, metrology and inspection that will provide the optimum solution for the hybrid manufacturing of large engineering parts of high integrity, with cost benefits of more than 50% compared to conventional machining processes.
For large scale engineering structures material needs to be deposited at a relatively high rate with exceptional properties and excellent integrity. To ensure this the machine is based on wire + arc additive manufacture for the additive process. A unique feature of the machine will be the capability for parallel manufacturing featuring either multiple deposition heads or concurrent addition and subtraction processes. To facilitate parallel manufacturing the machine architecture is based on robotics. To ensure that the surface finish and accuracy needed for engineering components is obtained for the subtractive step a parallel kinematic motion robot is employed. This robot is also used for application of cold work by rolling between passes. This ensures that material properties can be better than those of forged material.
A key part of this project is the development of ICT infrastructure and toolboxes needed to programme and run the machine. The implementation of parallel manufacturing is extremely challenging from a software perspective and this will be a major activity within the project. To deliver this extremely demanding and ambitious project a well-balanced expert team has been brought together. There are ten partners comprising six companies, two Universities and two research institutes. Two of the companies are SMEs and there are three end users from the renewable energy, construction and aerospace sectors. The consortium also features the whole of the supply chain needed to produce such a machine.
Hereon’s contributions are in the fields of cold-work aiming at a reduction and/or re-orientation of residual stress fields on additive manufactured produced components, the development of numerical models to understand different cold-work parameters on residual stress state, and the production of specimens in Ti and transition layers in dissimilar materials, e.g. Al/Steel using friction surfacing.
