Automated Finishing Recipe Determination for 3D Component Models
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated manufacturing methods for finishing operations, such as profiling and polishing of components like blades, rely on trial and error, leading to inefficiencies and a need for rework to meet strict specifications, and lack a systematic approach to determine optimal finishing recipes.
Innovation Solution
A computer-implemented method that processes non-finished and finished 3D models to calculate an initial finishing recipe, which is then optimized using a convergence algorithm based on quantitative differences, allowing for iterative refinement and dynamic adjustment to ensure precision and quality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If trial and error method is used to determine finishing recipe, then operator experience can be utilized, but time consumption and rework increase significantly
Solution Approach 1:
The patent replaces the manual trial-and-error method with an automated computer-implemented method that processes 3D models and applies convergence algorithms to determine the finishing recipe, eliminating operator time consumption while maintaining or improving recipe quality
Solution Approach 2:
The patent uses 3D digital models (virtual copies) of the component at different stages to analyze and determine the finishing recipe, replacing physical trial-and-error experimentation with virtual simulation and calculation
2Ease of operation
If manual operation of finishing tool is used, then flexibility is maintained, but manufacturing precision is insufficient
Solution Approach 1:
The patent replaces manual operation with automated computer-controlled finishing tool operation, where the computer calculates and executes precise tool paths based on 3D model analysis, achieving high manufacturing precision while maintaining operational flexibility through software control
Solution Approach 2:
The patent dynamically adjusts finishing parameters (tool path, speed, depth) based on quantitative differences identified through convergence algorithm analysis, allowing precise control of the finishing process to achieve required manufacturing precision
3Ease of manufacture
If conventional finishing method is used, then process simplicity is maintained, but rework is required to meet specifications
Solution Approach 1:
The patent performs preliminary analysis of the component's 3D models before the actual finishing operation to calculate the optimal finishing recipe and predict the outcome, allowing the process to be completed in one pass without requiring rework to meet specifications
Solution Approach 2:
The patent implements a feedback mechanism through convergence algorithm that compares the current component state with the target specification and iteratively adjusts the finishing recipe until specification compliance is achieved, ensuring precision without unnecessary rework
