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.

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.

Master Model

The main objective of the paper consists in remanufacturing of a part, through Abrasive Water Jet Cutting, using a method of reverse engineering based on 3D scanning. The characteristics of this process, the equipment and the main applications are presented. The research starts with manufacturing of a master model made by CFRP. This master model is a complex part cut by abrasive water jet cutting. In scanning process was used the 3D Scanner Artec Space Spider and the point cloud was processed using Artec Studio 11 software. By using this new 3D model was manufactured a new part, with the same setup. The quality characteristics (accuracy and surface quality) of this part was compared with the master model. The paper presents the advantages and disadvantages of this reverse engineering method applied on abrasive water jet cutting process.

Authors at work focused on the possibilities of using reverse engineering to study transport susceptibility of vehicles for air transport. The use of a 3D scanner gives the possibility of mapping in the form of a point cloud of the actual vehicle with all the defects and shortcomings that arose on the production line. Only 5 Hercules C-130 transport aircraft are used in the Armed Forces of the Republic of Poland. For this simple reason, access to these aircraft is limited. The aircraft's reloaded in 3D technology gives the possibility of a virtual fitting of the tested vehicle to the plane.

1D Modeling

Nowadays companies dealing with the automotive market, and in particular product designers, are facing with highly competitive environments though conflicting demands to deliver more complex products with increased quality in ever shorter development cycles. The usage of numerical simulations is therefore a confirmed technique going through the conceptual (1D) modeling towards a detailed digital mock-up to realize complex multibody (3D) simulations. The purpose of this paper is to develop a systematic design method for the suspension systems using CAE (Computer Aided Engineering) tools to investigate different properties which have influence on the ride & handling of a vehicle. Running a reverse engineering approach, the elasto-kinematic characteristics of different types of suspensions can be focused out and exported from a multibody environment (Virtual.Lab Motion has been chosen as example) as look-up tables to be read by a 1D multi-domain software (in the work here presented we used Imagine.Lab AMESim). Combined runs of sensitivity analyses and optimization cycles would then bring to the final goal of understanding the most suitable target behavior of the full system and the weight of different design variables on this, being hence able to directly address modifications of the global configuration.
