However, the high process complexity - inherent to AM operations - renders uncertain the quality performance of the final products. Consequently, there is often a need to assess the unique fabrication capabilities of AM against the reoccurring issues of process instability and end-product inconsistency. Improvement opportunities may be identified by empirically exploring the complex phenomena that regulate the quality performance of the final products. Thus, focused quality-screening and process optimization studies should additionally take into account the special need for speedy, practical and economical experimentation. Robust multi-factorial solvers should predict effect strength by relying on small samples while possibly dealing with non-linear and non-normal trends. We propose a nonparametric modification to the classical Taguchi method in order to enable the generation of rapid and robust screening/optimization predictions for an arbitrary 3D-printing process. The new methodology is elucidated in a recently published dataset that involves the difficult Taguchi screening/optimization application of a fused deposition process. We compare differences in the predicted effect-strength magnitudes between the two approaches. We comment on the practical advantages that the new technique might offer over the traditional Taguchi-based improvement analysis. The emphasis is placed on the ‘assumption-free’ aspect, which is embodied in the new solver. It is shown that the proposed tool is agile. It could also reliably support a customized 3D-printing process by offering robust and faster quality improvement predictions.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aime.2021.100051","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"107652867","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The surveyed students, were exposed to differently structured online courses from different institutes, as well as dynamic developments in each online course, over the semester and thus were able to effectively assess the pros and cons of the different teaching styles. To get the viewpoints of both the involved parties on how a successful online education course needs to be structured, a similar survey was also conducted among manufacturing engineering professors involved in Germany. The survey, a combination of Likert-scale and free-text questions, tackled the aspects of motivation to teach and learn, ensuring effective teaching and learning, and proper assessment of the learning outcomes in an online education system. The results show that both parties initially struggled with the transition, but later adapted quickly to the new style of online teaching that was inspired by the conventional flipped classroom concept. Certain structures and approaches to online teaching, such as pre-recorded lectures; interactive Q&A sessions; quizzes for self-assessment, are preferred by students and teachers alike. Aspects where the viewpoints differed could be explained by the difference in age and the experience in using digital equipment. A challenge specific to online engineering education is on offering laboratory experiences to students. Possible solutions such as virtual labs, remote labs and digital-live labs that aid in overcoming this challenge are presented. Finally, based on the survey results and the author experiences on digital laboratories, best practice guidelines are presented that will help the readers in the design and deployment of online engineering courses.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aime.2021.100058","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44359773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The obtained reduced order nonlinear parametric model serves as basis for the design of an Extended Kalman filter to estimate the spatial-temporal temperature distribution in the sheet metal blank during the forming process based on sparse local temperature measurements. To address modeling and approximation errors and to capture physical effects neglected during the approximation such as phase transformation from austenite to martensite a disturbance model is integrated into the Kalman filter to achieve joint state and disturbance estimation. The extension to spatial-temporal property estimation is introduced. The approach is evaluated for a hole-flanging process using a thermo-mechanical simulation model evaluated using LS-DYNA. Here, the number of states is reduced from approximately 17 000 to 30 while preserving the relevant dynamics and the computational time is 1000 times shorter. The performance of the combined temperature and disturbance estimation is validated in different simulation scenarios with three spatially fixed temperature measurements.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.aime.2021.100055","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72877449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are especially useful for applications like shaft and pipe couplings. In this work, we present the development and evaluation of a procedure to manufacture SM seamless couplings. After analysing industrial forming methods, we designed and fabricated a prototype of a punch-extrusion (PE) die and obtained seamless tubes of satisfactory quality and length for manufacturing couplings. Finally, we measured the performance and SM properties of the PE couplings and compared these characteristics to those of couplings machined from a cast ingot. We concluded that a multi-step processing is an efficient solution that mitigated problems resulting from billet cooling during punching because it allows the alloy to be reheated. The PE couplings that were diametrically expanded 4% and annealed at 700 °C exhibited 75% shape recovery, while the control samples showed 20% less recovery. The union of 21 mm diameter shafts by means of PE couplings annealed at 700 °C showed 40 N-m/cm<sup>2</sup> normalized torque transmission, which was 25% greater than that found for the cast ingot couplings. We also analyzed the advantages of the PE couplings compared to a traditional shrink-fit connection.</p></div>","PeriodicalId":34573,"journal":{"name":"Advances in Industrial and Manufacturing Engineering","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2666912921000313/pdfft?md5=1b2b01b8c4e01ef75abe41f2ffc83a18&pid=1-s2.0-S2666912921000313-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46331905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
