Journal of emerging technologies and innovative research, 2019
In the field of manufacturing and design industry, reverse engineering has proved to be beneficial for the growth and development of the mechanical industries. This technique has been generally accepted as an effective product design and development process technique. In standard computerized manufacturing system, the operating order normally begins with the concept of the product and finishes with various types of machine or CNC operations to turn raw material into finished product which is ready to enter in the market. Using some digitization methods, it is always necessary to replicate a CAD model of the actual component where the documents and drawings prepared by the designers are not accessible and are needed for review and modifications to create an enhanced product design. The essential steps involved in reverse engineering method include classification of geometric structures and associated surface depictions, segmentation & the surface fittings of the basic & free-forms model shape & the development of realistic CAD models. This paper discusses about the technique of reverse engineering and its implementation fields related to the advancement of product design. Redesign of the product and reverse engineering work would substantially minimize the costs and time required for manufacturing the physical components in the manufacturing industries.
Reverse engineering and CAD-CAM approach for manufacturing of spare parts. Case study
MATEC Web of Conferences, 2018
Reverse engineering represents a method to retrieve information from an existing product, information which are then used for designing a new product or to reproduce it in order to make spare parts. In this paper is presented a case study on making a spare part of complex shape from a worn part. There are presented the stages of acquisition of data by scanning, the use of reverse engineering for the realization of the 3D model, the virtual manufacturing and then the machining of the workpiece CNC machine tools.

The use of machines and devices causes their components to wear out, which leads to damage. The easiest and fastest method of repair is to replace this element with a new one. The problem arises when the desired element is not available on the market, technical documentation is unavailable or the costs of acquiring a new element are too high. In such a situation, engineering reconstruction, also known as reverse engineering, is used, which allows for the reconstruction of technical documentation and the production of a new product thanks to additive technology. The article presents the process of reverse engineering and the types of additive manufacturing technology. The aim of the article is to present the possibilities of using the reverse engineering method and 3D printing in the reconstruction of sample machine parts. The work uses the FDM (Fused Deposition Modeling) spatial production technology. The relevance of the article is confirmed by the possibility of its practical use in the field of machine servicing support.
Manufacturing Technology
The presented article deals with the application of Reverse Engineering and Rapid Prototyping processes in the development process in the automotive industry. In our case, we will focus on the design of the exterior rear view mirror. We obtained the information about the shape and as well as the data used to model the part in a virtual CAD computer environment by scanning it with a Leica laser scanner. The obtained point cloud was imported into CATIA V5 software, which is often used in the automotive industry. In the CATIA software modules, section curves were translated into cloud points. Based on these curves, free shaped surfaces of the mirror body and its holder on the car door were created. After creating the mirror body-mirror mount assembly, print data of these parts were generated for production by Rapid Prototyping technology. The printing method based on ABS material using the FDM (Fused Deposition Modeling) method was chosen.
Reverse Engineering – an Effective Tool for Design and Development of Mechanical Parts
2018
The Reverse Engineering has already found an extensive application in industry and other different fields. Reverse engineering (RE) is a process of taking the existing physical model and reproducing its surface geometry in three-dimensional (3D) data file on a computer-aided design (CAD) system. This paper will analyze the real situation in one industrial plant and provide comparative analysis of the application of current measuring methods and possibility of incorporating digital measurement. The Reverse Engineering (RE) is based on a method of reducing the time of dimensioning and modeling of mechanical parts which can be complex by geometry or dimensionally very accurate. In this paper we can give some practical examples of parts that are really produced in one manufacturing factory. Recommendation for digitalization will be of crucial importance for every company in its measurement and quality control activities.
MANUFACTURING OF RAPID PROTOTYPES OF MECHANICAL PARTS USING REVERSE ENGINEERING AND 3D PRINTING
Journal of the Serbian Society for Computational Mechanics, 2021
This article focuses on the design and manufacture of mechanical parts that have complicated shapes using the technique of reverse design using a scanner or an MMT for data acquisition in the form of a point cloud, using CAD software (CATIA). The digital model created is used for a virtual representation of the final product. Then we get the physical model on a 3D printer (also called additive manufacturing process) for later use in sand moulds. To have the imprint in the sand mould, we go through the fusion of the physical model (part). The use of this technique in the industry, allows us to save a lot of time in terms of model preparation and simple to implement, especially if it is mechanical parts that do not have a definition drawing, or they are worn out, then structural analysis was applied on the model using FE based software and tools to prove the quality of the product. Von Mises equivalent strains and stresses were predicted and decreased with increasing areas and honeycomb thickness. The objective of this article is to give an overview of this relatively modern technology and its various applications.

The purpose of this article is to introduce reverse engineering procedure (REP). It can achieved by developing an industrial mechanical product that had no design schemes throughout the 3D–Scanners. The aim of getting a geometric CAD model from 3D scanner is to present physical model. Generally, this used in specific applications, like commercial plan and manufacturing tasks. Having a digital data as stereolithography (STL) format. Converting the point cloud be can developed as a work in programming by producing triangles between focuses, a procedure known as triangulation. Then it could be easy to manufacture parts unknown documentation and transferred the information to CNC-machines. In this work, modification was proposed and used in RE program, which is from CAD-CAM software’s that used to redesign and modify on point of cloud in 3D modeling.

A CASE STUDY ON DESIGN OF THE COMPONENT FOR COMPLEX SHAPES USING REVERSE ENGINEERING
The paper describes about the state of art technology in preparing the existing component using digitized data by using optical scanners. Whereas the copy milling and CMM process was a traditional process by which the data could not be generated for creating a CAD model with precise accuracy.
