Integration of CAD/tool path data for 5-axis STEP-NC machining of free form/irrregular controured surfaces.

Anbalagan, Arivazhagan

Abstract

This research paper presents the work on feature recognition, tool path data generation and integration with STEP-NC (AP-238 format) for features having Free form/Irregular Contoured Surfaces(s) (FICS). Initially, the FICS features are modelled/imported in UG CAD package and a closeness index is generated. This is done by comparing the FICS features with basic B-Spines/Bezier curves/surfaces. Then blending functions are caculated by adopting convolution theorem. Based on the blending functions, contour offsett tool paths are generated and simulated for 5 axis milling environment. Finally, the tool path (CL) data is integrated with STEP-NC (AP-238) format. The tool path algorithm and STEP-NC data is tested with various industrial parts through an automated UFUNC plugin.
