Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Designers face challenges in creating casting hardware that provides sufficient machine stock while minimizing material costs, as existing methods rely on manual optimization prone to human error and variability in skill levels, leading to inefficiencies and non-compliance with manufacturability requirements.
Innovation Solution
A system and method that analyze casting and finished component models to identify machined surfaces, determine machine stock values based on distances, and provide graphical indicia influenced by a machine stock threshold, ensuring sufficient excess material is added to comply with manufacturability rules, using a processing system coupled with a display device and data storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual optimization of casting hardware is performed by designers, then design flexibility and adaptability are maintained, but reliability and consistency of meeting manufacturability requirements deteriorate due to human error and skill variability
Solution Approach 1:
The patent introduces an automated verification system that acts as an intermediary between the designer's casting hardware design and the manufacturability requirements. This system automatically calculates machine stock values, compares them against required thresholds, and provides feedback, thereby eliminating human error while preserving design flexibility.
Solution Approach 2:
The system provides automated feedback to designers by calculating machine stock values and comparing them to minimum required values. This feedback loop enables designers to iteratively refine their casting hardware designs while ensuring consistent compliance with manufacturability requirements, resolving the reliability issue without sacrificing adaptability.
2Manufacturing precision
If casting hardware provides more excess material than needed, then manufacturability requirements are satisfied, but material costs increase
Solution Approach 1:
The system automatically calculates the precise machine stock values based on the casting hardware design and compares them against minimum required values. This parameter-based verification enables optimization of material usage by ensuring sufficient but not excessive material is provided, thereby reducing material costs while maintaining manufacturability compliance.
Solution Approach 2:
The patent applies the principle of partial action by providing exactly the amount of machine stock needed rather than uniformly excessive material throughout. The automated verification identifies specific areas where minimum machine stock values are met, allowing optimization of material distribution to reduce overall material cost while ensuring manufacturability where required.
3Productivity
If automated verification system is implemented, then reliability and efficiency of verifying machine stock are improved, but device complexity increases
Solution Approach 1:
The verification system is integrated directly into the casting hardware design process, allowing the design software itself to perform the verification automatically. This self-service approach enables automated verification without requiring separate complex external systems, thereby improving productivity while minimizing the increase in overall system complexity.

AI summary
Systems and methods are provided for designing casting and finished component models used to fabricate corresponding casting hardware for a casted component and mechanical components fabricated therefrom. One exemplary method involves identifying a first subset of machined casting surfaces in a casting model of the casted component, identifying a second subset of machined feature surfaces in a finished model of the mechanical component, determining respective machine stock values associated the machined feature surfaces based on distances between the respective machined feature surfaces and the machined casting surfaces, and providing graphical indicia of the respective machine stock values that are influenced by the relationship between the respective machine stock values and a machine stock threshold.
