Computer aided design (CAD) automation of wood products

Ovim radom su ispitane prednosti automatizacije računalnog modeliranja korpusnog namještaja unutar računalnog programa Autodesk Inventor te Woodwork for Inventor (w4i), korištenjem ugrađenih funkcionalnosti iLogic i w4i te izrađenih mehanizama automatizacije. Izrađeno je ukupno dvanaest proizvoda, te su mjerena vremena potrebna za izradu 3D modela uporabom izrađenih mehanizama automatizacije i egzaktnom metodom modeliranja. Izračunate su konstrukcijske složenosti sklopova koje su se kretale od 0,29 do 1. Postavljena hipoteza o utjecaju automatizacije na ubrzanje procesa trodimenzionalnog modeliranja korpusnog namještaja dokazana je na svim primjerima proizvoda. Prosječno ubrzanje izrade trodimenzionalnog modela proizvoda automatizacijom je veće za 434,40 % u odnosu na izradu istog egzaktnom metodom modeliranja. Ovisno o kompleksnosti modela ono se kretalo od 300 – 483,33%, što predstavlja veliku uštedu vremena prilikom pripreme dokumentacije u proizvodnji namještaja i unutarnjeg opremanja.This paper examines the advantages of automating a 3D model of cabinet furniture within the CAD program Autodesk Inventor and Woodwork for Inventor (w4i), using the built-in functionalities of iLogic, w4i and developed mechanisms for automation. A total of twelve products were made, using the developed automation mechanisms and the exact modeling method, while the time required to create each 3D model was measured. The structural complexities of assemblies were calculated, ranging from 0,29 to 1. The hypothesis regarding the influence of automation on the acceleration of the process of 3D modeling of cabinet furniture was proved on all product examples. The average acceleration of the time required to create a 3D model of a product, with the use of automation, is higher by 434,40% compared to the exact modeling method. Depending on the complexity of the model, the acceleration ranged from 300 - 483,33%, which represents a significant reduction of time needed for the preparation of the documentation regarding the production of furniture and interior design
