Approach for Obtaining Broken Plastic Parts Using Reverse Engineering Tools

Abstract

Reverse engineering process has been demonstrated to be reliable solution in solving problems regarding missing information and/or details referred to the functional areas of parts. Based on the specific activities of the chain of processes that defines the reverse engineering concept it can be collected essential information in order to reconstitute important zones of broken parts. The present paper describes an approach that was used to recover a plastic gear part. The case study provided a moulded injected plastic part that was broken during the normal function. The entire process supposed scanning the toothed area that remained and rebuild the contour that was used in CAM software as input data and especially the machining strategy used to perform both sides of the part. The machining process was employed on a CNC graving machine tool.

Topology Optimization of an Airplane Component to Be Made by Selective Laser Melting Technology

“…The possibility of using composite materials in accordance with the requirements more and more restrictive regarding the size, shape, accuracy and mechanical properties of these types of components to be manufactured by using AM techniques are considered as top priorities for many important producers in the field of automotive and aerospace industry [6,7]. The possibility of using Reverse Engineering or 3D Scanning techniques, when a 3D CAD model is not available but is required for manufacturing the components using Additive Manufacturing (AM) techniques enlarged the possibilities of developing, designing and manufacturing new types of components [8,9]. Topology optimization is also widely used by the researchers, especially when decreasing the weight of components is mandatory [10,11].…”
