Analysis of the Wear on Machined Groove Profiles Using Reverse Engineering Technology

Abstract

One of the key components in making Industry 4.0 a reality includes machines that are able to produce re-quired products and components faster, more precisely and more flexibly than ever before based on so-called reverse engineering technology. Reverse engineering is a technology which enables rapid acquisition of data for CAD, CAM, CAE, thereby greatly shortening the development, design and fabrication of parts. In general, analog data is converted to digital data, which is further processed. The paper deals with the analysis of prototype models of disc milling cutters with different blade profiles. The inspection of the shape of the disc-type prototypes is based on the reading of the digitized reference CAD model (workpiece with machined grooves), the subsequent positioning of the digitized protrusions of the disc mill cutters (milling cutter with edge profile 1, milling cutter with edge profile 8) with respect to this reference CAD model, creating a colour map of the deviations at the selected points. The aim of the paper was to analyse the resulting wear (deviation of the dimensions at selected points) on the prototype of the disc milling cutters with the profiles of the blades 1 and 8, which was simplified on the workpiece with the machined profiles of the grooves 1 to 4.

Accuracy of Photogrammetric Models for 3D printed Wrist-hand Orthoses

“…A 3D printed WHO can be designed and fabricated by using reverse engineering and 3D printing techniques with some main steps as follows [2][3][4][5][6]: (i) Scanning the affected limb and converting the scanned model into a surface model, (ii) Designing the 3D model of the WHO, and (iii) 3D printing the WHO. The initial stage is associated with the process of reverse engineering, which allows for the digitization of a physical object and subsequently reconstructing its 3D model for additional applications [2,[5][6][7][8][9][10]. It is evident that expert 3D scanning systems can produce very good results, but they are still costly and need highly skilled workers to operate.…”

On the Impact of Surface Morphology and Transfer Film on Brake System Performance of High-Capacity Metro Train

“…The pneumatic brake system mainly consists of brake pads, aluminium composite brake discs, and brake cylinders. Aluminium alloys have excellent properties, such as high wear resistance, high strength, good corrosion resistance, and thermal stability, and are considered to be the most suitable structural material for aerospace and national defence industries [1][2][3][4][5][6]. This type of disc braking system has been widely adopted for use in high-speed trains due to its highly effective braking and heat dissipation properties, and aluminium-based hybrid composites with various reinforcements have attracted wide attention because of their multi-functional properties.…”
