English Abstract
Surface modeling utilizing B-spline technique is one of the most important tool in computer aided geometric design (CAGD).
The aim of this research is to build and develop an algorithm to design and implement multi-patches B-spline free-form surfaces.
The technique has an effective contribution in technology domains and in aircrafts, ships, and cars industry, moreover for its wide utilization in making the molds.
This work includes the synthesis of these patches in a way that allows the participation of these control points for the merged patches, and the confluence of patches at similar weights sides due to weights variation per patch.
Three different methods in surface design have been implemented such as (Blending method, cross-sectional method and lofting method) representing different types of B-spline surfaces.
Three models have been implemented to represent the different cases of designing methods.
The interior data of the desired surfaces designed by MATLAB software have been transformed to UG-NX8 software to get the machining process simulation and G-code programs for the three models, as well as a virtual machining process has been simulated to show the machining pitfalls, using VERICUT software.
The three samples have been machined using 3-axis vertical CNC machine (Isel) type.
Finally, the samples have been measured using Faro arm (CMM inspection) and it’s found that the average of error (0.10819 mm) for the blended model, (0.0589 mm) for the cross-sectional model, and (0.1337 mm) for the lofted model.
