Machining Feature Recognition Using Descriptors with Range Constraints for Mechanical 3D Models

International Journal of Precision Engineering and Manufacturing, 2023
In machining feature recognition, geometric elements generated in a three-dimensional computer-aided design model are identified. This technique is used in manufacturability evaluation, process planning, and tool path generation.

Incremental Recognition of Machining Features

ASME 1994 International Computers in Engineering Conference and Exhibition, 1994
Abstract Manufacturing analysis programs that operate in a batch mode are inappropriate for a concurrent engineering environment, in which designers interact with an evolving product model and require rapid feedback on the manufacturing implications of design actions. This paper discusses a design for an automatic recognizer of machining

Manufacturability evaluation of parts using descriptor-based machining feature recognition

International journal of computer integrated manufacturing (Print), 2021
Manufacturability validation refers to activities to evaluate the manufacturing cost of parts, manufacturing methods, and manufacturing difficulty, and to determine whether parts can be manufactured from three-dimensional (3D) computer-aided design (CAD)

Recognition of machining features - a hybrid approach

International Journal of Production Research, 2000
This paper describes a hybrid system which endeavours to recognize machining features automatically from a boundary representation (b-rep)-based solid modeller. The graph-based approach and the volume approach are adopted in consecutive stages in a prototype feature recognition system to combine the positive aspects of both strategies.

A Machining Feature Recognition Method Based on Transition Feature Simplification

2021 IEEE International Conference on Electrical Engineering and Mechatronics Technology (ICEEMT), 2021
In the 3D model of parts, transition features not only increase the number of nodes in the Face-Edge Attributed Adjacency Graph(FAAG) of parts but also destroy the topological structure of the original features. This will reduce the manufacturing feature recognition efficiency and accuracy.

Machining Feature Recognition for Cast Then Machined Parts

Volume 2: 19th Computers and Information in Engineering Conference, 1999
Abstract We present a method to recognize machining features for the domain of cast-then-machined parts. Non-interacting volumetric machining features are recognized through a face pattern based recognition approach, and are filtered out of the part model.

Recognition of Freeform Surface Machining Features

Journal of Computing and Information Science in Engineering, 2010
This paper describes a method of machining feature recognition from a freeform surface based on the relationship between unique machining patches and critical points on a component’s surface. The method uses Morse theory to extract critical surface points by defining a scalar function on the freeform surface.

Machining feature recognition for DFM evaluation

International Technology and Innovation Conference 2009 (ITIC 2009), 2009
Feature representation is vital to manufacturability evaluation, process planning, and NC programming. A machining oriented feature definition and taxonomy are proposed. Part is represented by B-rep representation with manufacturing information such as dimensions, tolerances, and surface roughness.

An adaptive feature recognition process for machining contexts

Advances in Engineering Software, 1994
This paper outlines the problem of CAD/CAM integration and presents a system for the automatic recognition of machining features. It is adaptable to the requirements of different environments giving the users the possibility of describing their own form features and inserting manufacturing information by using a teaching by example technique.
