VRM 3.0 (Variation Response Method), 2018

The tool offers the possibility to evaluate and optimise assembly fixtures, with the following capability:
• Variation Simulation Analysis (VSA) for deformable parts
• Assembly process simulation with compliant sheet-metal parts
• Fixture capability optimisation with stochastic product variations

• Fixture design synthesis of assembly systems
• Fixture design tasks’ integration at early-stage design
• Robust fixture layout optimisation with non-ideal sheet-metal parts
• Novel concept of fixture capability as a representation of the most likely feasible design solutions

The optimum fixture configuration is based on the concept of "Stochastic Fixture Capability" index, which allows for the estimation of a desired process fallout rate in the case of product quality failures or violation of process requirements during production, in the presence of stochastic variations as generating from real manufacturing process.
