Abstract AR
في هذا البحث تم استخدام T – SPLINE للنمذجة السطحية لمقارنتها مع النمذجة السطحية للـ NURBS للحصول على أفضل نقاط النمذجة بين الطريقتين.
و سوف تكون المقارنة من خلال تحليل السطح و عملية التصنيع.
أن أسطح T – SPLINE عادة ما تكون بيانات الهيكل الهندسي أقل في (50 – 70 %) من السطح المعادل للـ NURBS، و في قياس وقت التشغيل، سطح الـ T – SPLINE لنموذج مقعد الدراجة شغل في وقت أقل بمقدار (16 دقيقة) من تشغيل سطح الـ NURBS، و سطح الـ T – SPLINE للمقطع الطولي من نموذج الزجاجة شغل في وقت أقل بمقدار (10 دقائق) من تشغيل سطح الـ NURBS و في قياس الخشونة، سطح الـ T – SPLINE لنموذج مقعد الدراجة يمتلك (2.4861 ميكرون) و هو معدل (Ra) للبقع التي تم قياس معدل متوسط الخشونة لها، و سطح الـ NURBS يمتلك (4.9216 ميكرون) و هو معدل (Ra) للبقع التي تم قياس معدل متوسط الخشونة لها.
Abstract EN
This research uses T-spline for surface modeling and compares it with NURBS modeling to get the best modeling points between the two methods.
The comparison will be through surface analysis and manufacturing process.T-Splines surfaces typically have 50-70 % less geometric data structure than the equivalent NURBS surface, allowing for faster and more controlled direct editing and shape optimization.
In Environment Map analysis, the image of T-Spline surface for the models is reflected more clearly than a NURBS surface, in measurement runtime for machining (roughing and finishing), the T-spline surface for the bicycle seat model is machined in (16 minutes) less than machining the NURBS surface, and the T-Spline surface of the longitudinal section of the bottle model is machined in (10 minutes) less than machining the NURBS surface.
In measurement of roughness, the T-Spline surface for the bicycle seat model has (2.4861 μm) average (Ra) for patches measured roughness average (Ra), and the NURBS surface has (4.9216 μm) average (Ra) for patches measured roughness average (Ra).
