Treffer: Feature Extraction and CNC Code Generation for Prismatic Parts.

Introduction: In general, a designer creates a product based on their logic, incorporating certain constraints and assumptions. On the other hand, manufacturers interpret the design data based on their own logic, often making modifications during the production process. This disconnect between design intent and manufacturing execution leads to a gap in understanding, resulting in inconsistencies and inefficiencies. Currently, designers have no direct control over manufacturing process parameters, which limits the alignment between design and production. Ideally, the relationship between designer and manufacturer should be such that the manufacturing process accurately reflects the designer’s intent. This would allow designers to directly control the manufacturing parameters, reducing human intervention and minimizing errors. Methods: This paper proposes a novel methodology that enables automatic part feature extraction and CNC code generation for individualized product manufacturing. The aim is to optimize Computer-Aided Process Planning (CAPP) at the designer stage itself. Prismatic models are created using SolidWorks, and Principal Component Analysis (PCA) is applied to extract important features of these parts. Results: The PCA implementation is enhanced using logistic regression with hyperparameter tuning in Python. Automated feature extraction is achieved through specially designed algorithms that process signals without human involvement. Conclusion: By integrating feature extraction with decision-making algorithms, CNC codes can be generated automatically. This intelligent system streamlines the process, reducing product manufacturing errors, production time, and time-to-market. Major Findings: This study proposes an automated methodology for part feature extraction and CNC code generation to bridge the gap between design and manufacturing. PCA and logistic regression with hyperparameter tuning are used to enhance feature recognition from SolidWorks models. The approach enables real-time CAPP, reducing errors, production time, and aligning manufacturing with design intent. [ABSTRACT FROM AUTHOR]
