In order to cope with the new world economic conditions, a high degree of automation of production and assembly processes is required. As a result, industrial robots must also meet a new level of flexibility and versatility. It is now clear that it is very important to evaluate the performance as well as the safety characteristics, but especially the compatibility with the existing production system, as well as the compatibility with the possible evolution of the production system or even the substantial modification of the tasks of the industrial robot in a new production system, totally modified from the previous one. This requires the formulation of evaluation methods with relevant design metrics and quantitative methods based on simulations, which can support the mechanical designer of the robot, but especially the production system manager, to correlate the load-based performance characteristics, compatibility and safety of the industrial robot, taking into account the wide variety of possible solutions.","PeriodicalId":430778,"journal":{"name":"International Journal of Manufacturing Economics and Management","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127888778","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this sense, the use of biodegradable plastics is a more than the satisfactory alternative. However, in order to grow their performance, they constantly need to be improved, so composite materials based on biodegradable or recyclable polymers have started to be used frequently as a viable alternative. The present manuscript reveals the mechanical behavior of such composite material obtained by coating Arboblend V2 Nature granules with silver nanoparticles (AgNPs). The coating is intended to improve the antibacterial activity of the base material. The obtained results underlined the fact that with the incorporation of AgNPs in the polymer mass, the mechanical performances (tensile strength, bending strength, elongation, modulus of elasticity) of the material decrease visibly. Thus, the possibility of use of the parts in applications that involve exposure to pulling or bending is quite low, but can successfully replace other biodegradable/non-biodegradable polymeric materials that have metal particles in their structure and which do not present antibacterial action.","PeriodicalId":430778,"journal":{"name":"International Journal of Manufacturing Economics and Management","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134403412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Abrasive material water jet cutting is a processing process whose applicability is increasing in the conditions of the appearance of high-performance equipment. The technical optimization of this machining process aims at determining the distance between the machined material and the cutting head, determining the optimum length of the focusing tube, establishing the optimum machining pressure and determining the optimum amount of abrasive material so as to ensure maximum penetration depth of water jet with abrasive or minimizing surface roughness. During the research, the part subjected to abrasive water jet cutting was obtained by injection from Arboblend V2 Nature. The experiments were carried out according to a complete factorial plan 23, where the parameters on two levels were: water jet pressure, cutting speed and abrasive material flow. The optimization criterion followed was to minimize the standard roughness Ra. The experimental results showed that the parameter flow rate of abrasive material has the greatest influence on the roughness, the highest values of roughness are obtained when using a larger amount of abrasive (300g / min). The lowest value of the roughness of the cut surfaces is obtained for the following process parameters: low water pressure - 100MPa, high cutting speed - 150 mm / min and high flow of abrasive material - 300g / min.","PeriodicalId":430778,"journal":{"name":"International Journal of Manufacturing Economics and Management","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123477343","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hereinafter the reference is made to the problem of maximizing the production of the quantity of some mechanical units, which include several types of details required to assemble the unit in a certain quantity. The details are assumed to be manufactured and delivered to the assembly shop in a certain set. It is required to ensure the production of details on a specified number of machines for the assembly of maximum units for a fixed time. Any detail is expected to be produced on any machine. The same details can be produced in parallel. The optimization parameters will be provided by number of details of the required nomenclature, as produced with limited machine support used for the time-constraint production of these details. The production of a unit results from the available details of required nomenclature and its assembly from such details. We consider the production simulation model focused on maximizing the output of assemblies and increasing the efficiency of the use of available equipment. To solve the problem, we use the sporadic control mechanism for the number of manufactured details.","PeriodicalId":430778,"journal":{"name":"International Journal of Manufacturing Economics and Management","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126600804","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The quality requirements that must be followed by suppliers require permanent monitoring of processes of design, development, production, installation and service of products through audits qualified based on supply chain management. This paper presents an analysis of the supplier qualification process including the main phases as follows: evaluation, monitoring and auditing of suppliers in supply chain management. Internal quality audits and/or suppliers are one of the key instruments for ensuring sustainability and performance in supply chain management. Auditing of suppliers is a core component of the modern management of suppliers, with the help of which the customer can analyze precisely relevant processes to existing or potential suppliers. Supplier audits help both commercial partners to increase the transparency of the supply chain and also simplify supplier selection, evaluation, monitoring and development. The suppliers must meet the highest quality standards for products and processes. The main purpose of this paper is to give a general view of the supplier qualification process which involves the steps from initial identification until the inclusion of the supplier in the Approved Supplier List (LST). This list should be managed in such way that a complete traceability is assured. Following the proposed qualification diagram the customer can obtain an image about the status of one supplier, can also identify the weak points considering the evaluation, monitoring and audit class.","PeriodicalId":430778,"journal":{"name":"International Journal of Manufacturing Economics and Management","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130809187","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
