Unbridgeable gap between evolution of blueprint codes and communication – paradigm changing in production

Gyori M., Ficzere P., Lovas L.

Production Engineering Archives

2016

Vol. 12, No. 3

22--29

The traditional 2D drawing (hand drawing) in engineering has a commonly known communication code. These communication codes (type of line, width of line or other marks) makes the engineering communication easier, faster and safer. In the last couple of decades new computer aided design and manufacturing methods have been developed. The communication has been changed. This article aims to investigate the gap between software development and rules of communication. Although software support has developed the communication codes and basics have not been significantly changed. 2D drawing code is not yet fully included in modern 3D CAD software. Automatic 2D drawing generation from 3D computer models results problems, for example in sections, cuts and break-outs. This paper shows the most common problems and makes recommendation through harmonisation of the communication codes.

Usage of 3D printing in photostress investigation

Ficzere P.

Production Engineering Archives

2015

Vol. 7, No. 2

16--19

In this paper a theoretical analysis of load cases will be constructed, which are the most difficult to be determined during numerical simulations. The development of the design principles and methods are significantly influenced by technology development. Inappropriate design procedures and incomplete knowledge of the loads presents a significant risk factor. A strong emphasis should be put on determining the applicable conditions of coating layered optical photostress investigations for simplification of product validation. Future research should be focused on the views of industry representatives. Particular attention should be paid to the further clarification of the used 3D printing material properties and characteristics because these determine the conditions and limits of applicability. This would be a new application field of 3D printing.

Rapid prototyping in medical sciences

Horvath A. M., Ficzere P.

Production Engineering Archives

2015

Vol. 8, No. 3

28--31

Even if it sound a bit incredible rapid prototyping (RPT) as production method has been used for decades in other professions. Nevertheless medical science just started discover the possibilities of this technology and use the offered benefits of 3D printing. In this paper authors have investigated the pharmaceutical usage of rapid prototyping.
