Develop an interface to accept imported geometry from other CAD software packages. PHASE III: Validate previously developed parts optimized for multiple objectives through mechanical testing. The output geometry should be optimized for the chosen objectives (strength, stiffness, and/or weight) and be machinable by a multi-axis mill and/or lathe. Lastly, use a design as agreed upon between the United States Navy and the performer to demonstrate the software, ending with the fabrication of a component optimized for strength, stiffness and/or weight to be made on a multi-axis mill and/or lathe.The output of the software will be a CAD file(s) of neutral file type (i.e., Parasolid, STEP, IGES, or ACIS). Additionally, the software should incorporate “machinability” or ease/speed of manufacturing as a constraint. The software should constrain the analysis/optimization using a multi-axis subtractive machine as a constraint (i.e., the component must be manufactured on a multi-axis mill and/or lathe). PHASE II: Develop and prototype the software design from Phase I and demonstrate its ability to analyze/optimize a component for multiple objectives (e.g., strength and stiffness). The Phase I will include prototype plans to be developed in Phase II.
the component must manufactured on a multi-axis mill or lathe). Demonstrate the feasibility of the software to constrain the analysis/optimization using a multi-axis subtractive machine as a constraint (i.e. PHASE I: Design and develop a software to analyze/optimize a component for a particular objective (e.g. The output geometry should be optimized for the chosen objective and be machinable by multi-axis mill and/or lathe. The output from the Computer Aided Design (CAD) in the form of a common platform independent file type (e.g., Parasolid, Standard for the Exchange of Product model data (STEP), Initial Graphics Exchange Specification (IGES), or ACIS). To accomplish these goals, the Navy seeks the development of a software package that performs optimization for strength, stiffness, and weight as goals while using machinability as a constraint. Analysis of subtractive manufactured components requires material properties from the manufacturer and part geometry in order to be evaluated for airworthiness.This SBIR topic seeks to combine the strengths of material qualification associated with subtractive manufacturing and the benefits of optimization software to provide the best possible parts in the least amount of time.
Unlike additive manufacturing, components manufactured by subtractive manufacturing can be evaluated for airworthiness quickly by analysis. The issue for subtractive based manufacturing centers around tool-path and access (e.g., can the tool get into a space and move in the same space).The disadvantage of additive manufacturing is that both the process and material must be qualified and tested together in order to provide sufficient properties to be evaluated for airworthiness. However, the use of multi-axis numerical control subtractive manufacturing machines allows similarly complex shapes to be created. The mesh-based output is unusable for subtractive manufacturing without significant engineering input.Additively manufactured components have an advantage of being able to be created in complex shapes, which are unable to be made using subtractive methods. For additive manufacturing, a second software suite is needed to process the mesh-based output into usable format to produce the part. This mesh-based output is not generally in a format directly usable to create a part by either additive manufacturing or subtractive manufacturing.

The user inputs the various parameters (required strength, stiffness, or weight) and the optimization code calculates the topology to meet the user requirements.
