Machining feature-based similarity assessment algorithms for prismatic machined parts

Machining feature-based similarity assessment algorithms for prismatic machined parts

This paper presents algorithms for identifying machined parts in a database that are similar to a given query part based on machining features. In this paper we only consider parts that are machined on 3-axis machining centers. We utilize reduced feature vectors consisting of machining feature access directions, feature types, feature volumes, feature dimensional tolerances and feature group ca...

CAD/CAM integration based on machining features for prismatic parts

Machining Feature-Based Comparisons of Mechanical Parts

Solid Models are the critical data elements in modern Computer-Aided Design (CAD) environments, describing the shape and form of manufactured artifacts. Their growing ubiquity has created new problems in how to effectively manage the many models that are now stored in the digital libraries for large design and manufacturing enterprises. Existing techniques from engineering literature and indust...

Identifying Similar Parts for Assisting Cost Estimation of Prismatic Machined Parts

This paper presents a method for identifying those parts in a database that are similar to a given query part to be machined and hence can be potentially used as a basis for estimating the machining cost of the query part. We utilize projected feature vectors consisting of feature access directions, feature types, and feature volumes as a basis for assessing shape similarity. We have defined a ...

A New Methodology to Extract Machining Features From Prismatic Parts

Feature recognition systems are now widely identified as a cornerstone for conceiving an automated process planning system. Various techniques have been reported in the literature, but a few of them acquired a status of generic methodology. This research aims to exploit the concept of automatic feature recognition system. The boundary (B-rep) geometrical information of the part design is analyz...
