3D virtual prototyping of a ski jumpsuit based on a reconstructed body scan model
Zoran Stjepanović, Andreja Rudolf, Simona Jevšnik, Andrej Cupar, Vojko Pogačar, Jelka Geršak, 2011, izvirni znanstveni članek

Opis: 3D virtual prototyping become a topic of increasing interest of both computer graphics and computer-aided design for apparel production. These technologies are especially important when a garment prototype should be developed for a special purpose, such as ski-jumper suit. Namely, shape and size of a jumpsuit need to be individually adapted to each ski-jumper according to the exact requirements set by FIS (Fédereation Internationale de Ski). The FIS requirements change annually or even more often in order to assure ski-jumpers' safety during competitive ski jumps. The conventional body measurement technique and development of ski-jumpers pattern are time consuming. In order to develop an accurate and rapid design, as well as an adaptable and quickly changeable jumpsuit, different modern technologies were used. The obtained virtual prototypes of a skijumper and a jumpsuit enable both - fast re-modelling according to FIS rules and expeditious development and/or simulations of a jumpsuit. All these measures are taken to improve the aerodynamic design of a suit and jumper's result. The body scanning technology represents a great potential for textile industries and above all for producers of garments. It enables fast and reliable capture of 3D body data and extraction of precise measurements needed for design, construction, visualisation and animation of garments on virtual mannequins. However, there are also some problems related to the scanned body models, caused by the scanning technique. In this article we are discussing the techniques for reconstruction of the body models and its results using the example from one of the competitive sports clothing - ski-jumper suit. In our study we have used different computer graphics programmes in order to reconstruct and prepare the 3D body scan model for successfully importing it into OptiTex CAD programme. The aim of this research was to enable effective 3D virtual garment prototyping using the reconstructed body scan model.

Design and construction of the technological process of product production
Marko Drempetić, 2016, magistrsko delo

Opis: Master’s thesis contains technological procedure for developing product which includes design, making of technological documentation, choosing parameters for CNC machining, and measuring of the final product. The product from this master thesis is “Oil control block”. This is one of the parts of the high voltage switchgear GIS „Gas Insulated Switchgear“ which is used for regulation of pressure during switching. The product is made from material C45 (1.0503) according to European norm EN 10277-2-2008. The technological process is shown in spreadsheet view. Also it’s explained the workholding device and the way of using it, then it’s shown the technological documentation which follows the machining process, then the NC program and 3D model. It will be shown the CNC milling machine "Matsuura H.Plus-630 Horizontal Machining Center" and the parameters for machining process. After machining process is done the workpiece is sent to the Quality Control Department where it is checked GD&T. Dimension are controlled on 3D coordinate measurement system “FARO” then the control list is generated with the appropriate software.
