3D Digitizing

The paper deals with a description of the creation of CAD model (file format .IGES) based on polygon mesh (file format .STL) obtained by 3D scanning. On the basis of the imported polygon mesh into Reverse Engineering software, it is possible to create surface (or solid) CAD model. For CAD model created from a polygon mesh, a model of screw propeller was chosen. The paper also presents a color deviation map acquired by comparison between a polygon mesh and a CAD model. The 3D digitizing was performed by 3D scanner GOM ATOS II SO TripleScan; GOM ATOS Professional v7.5 SR2 software was used for processing of the scanned data and Delcam PowerSHAPE 2015 CAD software was used for reverse modeling.

Recently, automatic 3D scanning devices are commonly researched and developed for better productivity of the reverse engineering fields. In this paper, a 3D scanner utilizing a spherical coordinate system was designed and analyzed using FEM analysis. The system was designed for optimal performance, high precision, minimal deflection, and speed of data collection. FEM analysis allowed us to properly design the system to achieve these goals, with focus on the deflection of the cantilever arm. Results of the FEM analysis and figures showing the apparatus design are provided. Successive prototypes are shown to increase in overall performance and reliability through improved design and analysis.

Industri kreatif memiliki kontribusi yang besar bagi perekonomian Indonesia, membuka lapangan kerja baru, serta memperkuat citra dan identitas bangsa. Salah satu bagian dari industri kreatif adalah pengrajin kulit. Produk yang dihasilkan oleh pengrajin cukup bervariasi, seperti dompet, sepatu, tas, dll. Material kulit yang digunakan berupa kulit asli atau kulit sintetis. Salah satu proses dalam menghasilkan produk-produk tersebut adalah embossing untuk membentuk pola hias atau merk. Embossing dapat dilakukan dengan dengan high frequency welding. High frequency welding merupakan penyatuan material dengan menggunakan energi elektromagnetik frekuensi tinggi untuk menghasilkan panas pada material polar sehingga meleleh dan menghasilkan bentuk seperti yang diinginkan setelah proses pendinginan. Laboratorium Proses Produksi Program Studi Teknik Industri memiliki mesin high frequency welding yang dapat digunakan sebagai materi praktikum serta membantu pengrajin kulit kota Bandung, khususnya pengrajin kulit Cibaduyut untuk menghasilkan emboss yang baik. Embossing kulit sintetis dan kulit asli memerlukan parameter proses yang berbeda, hal ini disebabkan sifat fisik setiap jenis kulit. Oleh karena itu diteliti parameter yang tepat untuk menghasilkan emboss kulit sintetis. Penelitian ini menggunakan kulit sintetis yang terbuat dari PVC (Polivinil Klorida). Cetakan yang digunakan merupakan cetakan sederhana berbentuk 2 lingkaran, yaitu lingkaran dalam dan lingkaran luar. Parameter yang diteliti terdiri dari 2 parameter, yaitu suhu dan waktu pengelasan. Eksperimen dilakukan dengan 3 level suhu, yaitu 140°C, 160°C, dan 170°C sedangkan waktu pengelasan dilakukan dengan 3 level yaitu 3 detik, 7 detik, dan 10 detik. Response dari eksperimen ini adalah jari-jari dalam dan jari-jari luar emboss. Hasil proses embossing dipindai dengan menggunakan 3D Scanner dan kemudian dilakukan pengukuran dengan menggunakan perangkat lunak reverse engineering. Pengaruh dari kedua faktor dan interaksinya diketahui dengan menggunakan ANOVA. Pairwise comparison dilakukan dengan menggunakan Tukey’s method. Hasil yang diperoleh adalah suhu mempengaruhi response. Berdasarkan percobaan yang dilakukan hasil embossing dengan suhu sebesar 170oC lebih baik daripada 140oC atau 160oC. Kata kunci: high frequency welding, design of experiment, kulit sintetis, pvc

Product designing requires concept development tool like TRIZ to obtain innovative solutions. In this paper, we have applied available concept development and design tool to develop a relationship between the problem definitions, identified as per customer needs, and the design of the products physical parameters complying with the required specifications. Product development techniques like Reverse Engineering, Surface Modeling, and Rapid Prototyping technologies are employed to improve the existing design of a specific problem. These technologies are used for customization of product and are helpful for research and development purpose. In this paper, the outer body of an existing car is redesigned, and we have further created a prototype with improved aerodynamics and futuristic aesthetics. In this Additive Manufacturing (AM) process, Steinbichler 3D Scanner, Projet 3D printer and associated Scanning and printing software are used, by which redesign and associated development process of a car become easy in lesser time and cost.

Novel Technologies

In this paper, a systematic scheme is proposed and novel technologies are developed to automatically reconstruct a CAD model from a set of point clouds scanned from the boundary surface of an existing object. The proposed scheme is composed of three major steps. In the first step, multiple input point clouds are incrementally integrated into a watertight triangle mesh to recover the object shape. In the second step, mesh segmentation is applied to the triangle mesh to extract individual geometric feature surfaces. Finally, the manifold topology describing the connectivity information between different geometric surfaces is automatically extracted and the mathematical description of each geometric feature is computed. The computed topology and geometry information represented in ACIS modeling kernel form a CAD model that may be used for various downstream applications. Compared with prior work, the proposed approach has the unique advantage that the processes of recognizing geometric features and of reconstructing CAD models are fully automated. Integrated with state of the art scanning devices, the developed model reconstruction method can be used to support reverse engineering of high precision mechanical components. It has potential applications to many engineering problems with a major impact on rapid design and prototyping, shape analysis, and virtual reality.
