This phenomenon referred to as galling adversely affects sheared edge quality and increases energy consumption. An instrumented pneumatic press was designed and built to conduct shear–punch tests on 2 mm-thick AA5754-O sheets and to investigate the progression of galling to AISI M2 steel punching tools during dry and lubricated punching. The punching tests were performed using a clearance of 2.0% of the lower die diameter. Cumulative galling volumes were measured using a non-contact optical surface profilometer, and the rate of material transfer (the galling rate) was estimated for both dry and lubricated punching.

By 3D printing zirconia lattices, the density can be modulated spatially by varying strut and beam thicknesses at arbitrary positions (such as when following a spatial function). As the effective permittivity is related to the density, the speed of electromagnetic radiation (the speed of light, c) can be controlled in the 3D space.

The main objective of this paper is the identification of basic components comprising human-robot collaborative systems design. This is supported by two steps, 1) Provide an extensive compendium of current applications and components within a varied set of manufacturing sectors and tasks. 2) Based on the latter, propose a selection of “structural components” for collaborative work. We conceptualized structural components as the organizational and technological alternatives necessary to fulfil the basic requirements and functionalities of human-robot collaborative systems. This document presents a systematic literature review that includes 50 exemplary case studies implemented in different manufacturing environments throughout the last five years praxis (2016–2020). Four structural components were identified in this paper: interaction levels, work roles, communication interfaces and safety control modes. Furthermore, it was found that physical contact-based collaboration for screwing assembly of small-sized parts and material handling of heavyweight objects are suitable applications for the automotive industry. Moreover, certified augmented and virtual reality devices were highlighted as convenient assistive technologies for safety and training manufacturing needs.

For this purpose, several tensile tests were carried out on sheet metal samples up to a defined plastic strain. The specimens were left in the clamping device in order to relieve the force in several steps until the specimen was completely relieved. As a consequence, the gradual relief leads to a reduction of internal stress states. During the forming process, the initial magnetic relative permeability and magnetic anisotropy of the sample were measured several times. Both properties are related to the mechanical states in the material through the effects of magnetic embrittlement and magneto-elasticity. The plastic strain of the specimens was determined by optical measurements and the stresses in the measurement range during the tensile test was determined with the help of a subsequent numerical simulation. This made it possible for the first time to measure the magnetic properties of samples with different plastic strain and different stress states. The evaluation shows that there is a strong correlation between permeability and plastic strain as well as anisotropy and stress. Based on these findings, it has been confirmed, that the determination of the plastic strain by a soft sensor is possible.</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.2021.100053","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"113005076","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}
