Sheet metal-based products serve as a major portion of the furniture market and maintain higher quality standards by being competitive. During industrial processes, while converting a sheet metal to an end product, new defects are observed and thus need to be identified carefully. Recent studies have shown scratches, bumps, and pollution/dust are identified, but orange peel defects present overall a new challenge. So our model identifies scratches, bumps, and dust by using computer vision algorithms, whereas orange peel defect detection with deep learning have a better performance. The goal of this paper was to resolve artificial intelligence (AI) as an AI landing challenge faced in identifying various kinds of sheet metal-based product defects by ALDB-DL process automation. Therefore, our system model consists of multiple cameras from two different angles to capture the defects of the sheet metal-based drawer box. The aim of this paper was to solve multiple defects detection as design and implementation of Industrial process integration with AI by Automated Optical Inspection (AOI) for sheet metal-based drawer box defect detection, stated as AI Landing for sheet metal-based Drawer Box defect detection using Deep Learning (ALDB-DL). Therefore, the scope was given as achieving higher accuracy using multi-camera-based image feature extraction using computer vision and deep learning algorithm for defect classification in AOI. We used SHapley Additive exPlanations (SHAP) values for pre-processing, LeNet with a (1 × 1) convolution filter, and a Global Average Pooling (GAP) Convolutional Neural Network (CNN) algorithm to achieve the best results. It has applications for sheet metal-based product industries with improvised quality control for edge and surface detection. The results were competitive as the precision, recall, and area under the curve were 1.00, 0.99, and 0.98, respectively. Successively, the discussion section presents a detailed insight view about the industrial functioning with ALDB-DL experience sharing.

In order to realize the manufacturing defects detection of sheet metal parts, a kind of defects detection method of the sheet metal parts based on region morphology has been put forward based on HALCON using the mathematical morphology knowledge: by choosing the proper structuring element and neatly applying dilation, erosion, opening and closing on the defects images, the defect part is extracted. The experiment shows that the effect of this method is good and the calculation and processing speed is fast.

There are the four types of defects during remote laser welding of zinc coated sheet metal. The root cause of all these defects is the explosion or ejection of molten weld metal caused by the escape of trapped high pressurized zinc vapor. De-gassing gapping is a method used to solve the defects. We have researched the silicon powder de-gassing gapping method for remote laser welding with coupons of zinc coated sheet metal. The result shows that silicon powder de-gassing gapping method works well.

Abstract: Manufacturing is the process of turning raw materials or parts into finished goods through the use of tools, human labor, machinery, and chemical processing. In Aerospace industry, the most commonly used manufacturing process is sheet metal forming processes that helps in manufacturing the parts for tons of known and unknown purposes. Sheet metal forming process is done on a press and the parts are formed in between two die. It involves reshaping a metal while it is still in its solid state. Example of sheet metal forming process are bending, stretch forming, deep drawing, etc. But in aerospace industry, their exists some parts which occurs wrinkling defect while forming process, which is because of uncontrolled material flow into the die radius and no holding for the blank during forming , needs to be rectified. It is one of the major defects in sheet metal forming processes. It may become a serious obstacle to implementing the forming process and assembling the parts, and severe wrinkling may leads to break the part

Pulsed phase thermography (PPT) is a common infrared technique for quantitative nondestructive testing and evaluation (NDT&E). PPT was initially applied in the aeronautical and aerospace engineering to the detection and quantification of defects in materials with either high or low thermal conductivity, such as aluminium and composite materials. This paper presents for the first time the application of PPT-technique for defect inspection in sheet metal parts, attempting to provide a solution for an alternative quality control rather than the traditional optical survey in the press shop. The inspected defects in this paper were produced in deep drawing cups, to effectively creating various crack lengths and depths respectively in both steel and aluminium alloys. The approach of the characterizing influence parameters is primarily based on the particular parameters of the PPT-technique. These parameters were firstly classified into various categories, and a DoE model was subsequently designed to define the required experiments for a process window analysis. According to the defined process window, more accurate conclusions of defect detecting effects were achieved. Studies in the paper present the fundamental perceptions for defect inspecting in the sheet metal parts by using PPT-technique in the press shop.

Resumo: Este trabalho tem como objetivo caracterizar mecanica e metalograficamente, juntas soldadas de chapas finas em aço Maraging 300, submetidas a até três reparos, usadas na fabricação de envelopes motores foguete a propelente sólido desenvolvidos no Instituto de Aeronáutica e Espaço (IAE) em atendimento às necessidades de sua gama de lançadores. O envelope motor atua como elemento estrutural e também possui a função primária de suportar a pressão de trabalho durante a queima do propelente. Atualmente, o envelope motor é fabricado em aço 300M-ESR e o IAE tomou a decisão de substituí-lo pelo aço Maraging 300. Em função dos processos existentes no Instituto, neste trabalho utilizaram-se os processos de soldagem Plasma Arc Welding - PAW com a técnica keyhole e Gas Tungsten Arc Welding - GTAW, ambos em passe único, com metal de adição. Antes de serem submetidas aos ensaios, as juntas passaram por inspeção não destrutiva de acordo com os critérios da norma AWS D17.1. Os reparos foram feitos de forma manual e processo GTAW. Amostras da junta soldada e reparadas foram submetidas a ensaios de tração, dureza Vickers (HV) por microindentações, análises químicas, análises metalográficas e fractográficas. Corpos de prova dos cordões adjacentes aos reparos também foram avaliados. Os resultados mostram que após a solda e reparos e o tratamento térmico de solubilização e envelhecimento, a zona fundida e a região da linha de fusão da solda apresentam uma dureza abaixo das outras regiões afetadas termicamente. Para as condições da solda sem reparo e reparadas, o processo PAW apresentou um valor menor de dureza em todas estas regiões com relação ao processo GTAW. As análises da superfície dos corpos de prova soldados rompidos indicam o predomínio de um processo de ruptura iniciado próximo à linha de fusão da solda e que se propaga em direção ao interior do ...

Abstract: This work aims at mechanic and metallographic characterization of Maraging 300 welded joints sheets, submitted to up to three repairs, used for the fabrication of solid propellant rocket motors at the Institute of Aeronautics and Space - IAE as to comply with its range of launchers. The rocket motor is a structural part and also has the primary function of supporting the nominal pressure during the propellant burning. At present, the rocket motor is fabricated in 300M-ESR steel and IAE has decided to replace such a steel for the Maraging 300 one. Due to IAE's existing processes, Plasma Arc Welding - PAW with the keyhole technique and the Gas Tungsten Arc Welding - GTAW have been used, both single-pass welding with filler. Before they have been submitted to the tests, the joints went through non-destructive inspection according to AWS D17.1 Standard. Manual repairs and GTAW process have been made. Samples of the welded and repaired joints were submitted to tensile testing, Vickers hardness, chemical analysis, fractrographic and metallographic analysis. Body tests of the beads adjacent to the repairs have also been assessed. Results show that after welding, repairs and solubilization and aging heating treatment, the melted zone as well as the weld joins lines zone present hardness below other heat affected zones. As for the conditions of the non-repaired and repaired welds, the PAW process has demonstrated lower hardness values in all zones in what regards the GTAW process. The welded and fractured body tests surfaces analysis indicate the predominance of a fracture process started next to the weld joins lines which goes towards the bead interior. The nature of the fracture has shown the predominance of dimples. The GTAW welded body tests presented higher mechanical strength than that of the PAW process. Similarly, the PAW welded body tests obtained from the beads of the zones ... (Complete abstract click electronic access below)

This study focuses on the bending die design which can skip notching operation for bending of the galvanized sheet metal with inclined multi-stage features. Relief geometries were designed to cope with the offset profile punch to improve the wrinkling and material piling up in the conventional offset punch designs. Occurrence of wrinkling and fracturing defects is due to vertically off-plane bending line that is composed of non-continuous lines on the vertical plane. The offset punch profile with relief geometries was proposed to avoid the wrinkling and fracturing defects caused by extra material pile up in the vertically off-plane bending line corners. The effects of inclined angle of the pre-bent zigzag blank were studied to establish the applicability of the offset punch profile design. CAE method was integrated with the design of experiments (DOE) method to predict the material flow and study the effect of the different die and process design factors. Multi-relief punch design was proposed to control the material flow and pile up zone. The control point updating algorithm of a Bezier curve was applied to design the blank pre-cutting profile to minimize the zigzag of bending edge effectively. The simulation results had shown that wrinkling and fracturing defects will occur in case of the inclined angles lager than 80 degrees. The required relief width is proportional to the width of bending edge. The experimental results were in good agreement with the predictions of simulation. The proposed relieved offset punch design and edge pre-cutting profile were able to avoid defects of paint-scratching, wrinkling, fracturing, and zigzag of product edge.

Dissertação de Mestrado Integrado em Engenharia Mecânica apresentada à Faculdade de Ciências e Tecnologia
Atualmente, o processo de conformação plástica de chapas metálicas é amplamente utilizado na indústria automóvel. A capacidade de resposta deste sector às crescentes exigências do mercado, com a qualidade e a brevidade necessárias, é devidamente aumentada com a utilização de ferramentas de apoio à produção, nomeadamente a aplicação de simulação numérica com o método de elementos finitos. Este instrumento é utilizado para a validação e otimização de ferramentas e parâmetros de processo de estampagem de chapas metálicas, nomeadamente com a previsão da ocorrência de defeitos, permitindo a redução de custos e ciclos de desenvolvimento do produto. Este trabalho tem como objetivo realizar a modelação e simulação do processo de estampagem multi-etapa de um componente automóvel, nomeadamente de um pedal de travão de um automóvel. A produção deste componente envolve corte por arrombamento e dobragem em ferramentas progressivas, sendo a simulação numérica realizada no programa de elementos finitos DD3IMP. As ferramentas de conformação são consideradas rígidas na simulação numérica, enquanto o pedal tem um comportamento elasto-plástico, descrito por um critério de plasticidade anisotrópico (Hill’48) e uma lei de encruamento isotrópico (Swift). Dois lotes do aço S420MC são utilizados na produção do pedal de travão, os quais são considerados na simulação, sendo que para um lote são observados defeitos de fissuração em zonas de corte por arrombamento. Relativamente à discretização espacial do corpo deformável, são utilizados elementos sólidos hexaédricos de 8 nós. A análise e comparação de resultados da simulação dos dois lotes de material, nomeadamente da deformação plástica equivalente, tensão de escoamento e trajetórias de deformação em alguns pontos estrategicamente escolhidos, demonstra os diferentes comportamentos dos dois lotes de materiais em estudo. Estas diferenças permitem efetuar conclusões que sustentam a presença/ausência de defeitos de fissuração nos produtos resultantes dos processos de estampagem multi-etapa. O aumento de camadas de elementos finitos em espessura do modelo numérico tem pouca influência nos resultados de deformação plástica equivalente e de tensão de escoamento nos pontos críticos analisados, permitindo a validação dos resultados com a discretização mais grosseira.
Nowadays, the sheet metal forming process is widely used in industry, especially in the automotive sector. The sector's answer to the increasing market requirements, with the necessary quality and briefness, is properly increased using production support tools, namely numerical simulation using the finite element method. This instrument is used for the validation and optimization of tools and parameters of the sheet metal forming process, namely with the prediction of defects, allowing the reduction of costs and product development cycles.This work aims to perform the modelling and simulation of the multi-stage sheet metal forming process of an automotive component, namely a car brake pedal. The production of this component involves blanking and bending in progressive tools, and the numerical simulation is performed in the DD3IMP finite element program. The conformation tools are considered rigid in the numerical simulation and their surfaces, while the pedal has an elasto-plastic behaviour described by an anisotropic yield criterion (Hill’48) and an isotropic hardening law (Swift). Two batches of S420MC steels used in the production of the brake pedal are considered in the simulation, where edge cracking is observed for one batch. Regarding to the spatial discretization of the deformable body, 8-node hexahedral solid elements are used.The analysis and comparison of simulation results of the two batches the material, namely the equivalent plastic strain, flow stress and strain paths at some strategically chosen points, demonstrates the different behaviours of the two batches of studied materials. These differences allow conclusions to be drawn that support the presence / absence of edge cracking in products resulting from multi-stage forming processes. The increase of finite element layers in thickness of the numerical model has little influence on the results of equivalent plastic strain and flow stress at the analysed critical points, allowing the validation of the results with the coarser discretization.

Deep drawing is a cost effective sheet metal forming process to produce many industrial components. However, complex geometrical drawn parts are difficult to form due to several modes and conditions of the material flow. Commonly problems associated to the forming operation are wrinkling and tearing defects, which affect the cost and quality of the parts. Actually, there are not theoretical methods developed in the literature yet, so the trial and error method are used to reduce or eliminate the deep drawing defects or inclusive is utilized in the earlier production stages, resulting in higher costs and longer production times. This paper describe a proposed solution to reduce or eliminate the wrinkles defects on the flanges of an industrial fan support that result from applying the forming process. An analysis procedure based on the development of the correct sheet metal blank considering three different blank geometries was proposed. The analysis include the analytical methods available in the literature, the simulation with a computer program based on the Finite Element Method (FEM) and experimentation. FEM model, simulation and results, these were validated by measuring the thickness profile on the flanges of a deep drawing part, before and after the procedure implementation. The results have shown that combining both the analytical and FEM methods, were possible to know the influence degree of the sheet metal blank geometry to reduce or eliminate the wrinkle defect and these can be used as an effective design tool.

This paper considers the use of finite element simulation of sheet metal forming as a tool to evaluate geometrical defects caused by elastic springback. The simulations aim to provide reliable information about the deviation of the real part geometry from that defined in the design phase in order to overcome the subsequent assembly problems. The material studied and presented in this paper is stainless steel 410. In order to determine the material properties and the parameters needed for the simulations, a series of experiments including uniaxial and cyclic tests were carried out. Moreover, bending experiments were conducted so that simulation results can be verified against simple forming operations. To expand the use of the model to predict the effect of forming parameters on springback, an aircraft engine cone-shaped component was simulated and the results were compared to the actual formed part. Predictions of the final shape and thickness variation were successfully obtained and were in agreement with the cone forming experiments.

Flexible media such as tape, web or sheet metal are commonly used in the mass production manufacturing. In the modern manufacturing process, about one third of the steel production is converted to sheet metal [1]. Sheet metal is normally winded and stored into coil form which can be easily tranported. However, when it is unwinded for metal forming process such as press stamping, laser cutting or any other forming process, sheet metal will have coilset residual stress which can cause defects from the forming process. The coilset residual stress is caused by the way the sheet metal is stored and packaged [2]. Therefore, in order to eliminate such residual stress, leveing process is carried out to eliminate common coilset residual stress.
