“…For the full transition complexity assessment, the compatibility of a configuration is determined for an operation based on a set of machine characteristics. There can be levels of compatibility, and this is used as the basis for subsequent analysis [13]. This is not required here, but a subset of methodology can be used to compare physical reconfiguration options.…”

Simulation tools need to be developed to support modeling and product/process analysis activities for material deposition processes. The long term research goal is to develop a set of virtual modeling tools to support advanced tool motions and process planning strategies for this application. The goal of this research is to develop a reconfigurable robotic platform that can adapt alternative deposition strategies while respecting the unique process-related constraints for 2 1 /2 axis and 2 1 /2 axis + 2 axis tool paths. A variety of topologies are investigated. For the selected systems, a parametric kinematic, dynamic and control model is developed, and results presented for kinematic and dynamic reconfigurations. An adaptability assessment is performed to determine a relative effort measure to physically reconfigure a base platform to a potential new configuration. This combined with reviewing the modeling complexity issue, is used to determine an appropriate base platform. To simulate the process realistically using existing tools, a methodology is developed to illustrate material deposition in conjunction with the tool motions for the systems investigated.
