Despite being promoted and supported by the state, the introduction of these modern methods is still not as widespread as in other EU member states. The reason for this is the heterogeneity of firms: there are substantial differences between large and small as well as foreign and domestic firms. Statistics, surveys and interviews have proven that foreign-owned, larger companies are front-runners, while smaller domestic ones face considerable financial and technological challenges. However, it is concluded that the main problem is the continued lack of the necessary skilled labour force.","PeriodicalId":43118,"journal":{"name":"Hungarian Journal of Industry and Chemistry","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69557497","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 necessity to increase the strength of materials and minimize their weight in the automotive and aviation industries has urged engineers and scientists to conduct more investigations and identify manufacturing methods to replace the classical ones. Additive manufacturing involves building a geometry layer by layer from a wide range of materials, which helps to utilize materials efficiently while minimizing the amount of waste produced as well as build complex, large geometries and light-weight components. Furthermore, it minimizes fabrication and processing times. In this paper, three different alloys were printed (TiAl6V4, AlSi10Mg and 316L) using MSC Simufact software to investigate the effect of changing machines on the effective stress and surface deviation. Furthermore, thermal analysis as well as mechanical, thermal and thermomechanical calibrations were carried out to determine a parameter set consisting of the laser power, inherent strains, fraction of exposure energy and volumetric expansion factor.","PeriodicalId":43118,"journal":{"name":"Hungarian Journal of Industry and Chemistry","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69557640","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}

With their universal gripper they can handle a wide range of tasks, however, custom accessories may need to be produced in specific areas. One such accessory could be sleeves that are mounted on the grippers to extend the use of the universal gripper.

The ball-end mill is mainly used in machining such surfaces. However, the manufacture of this type of surface is still somewhat difficult when machining using a 3D ball-end milling machine. Due to changes in the surface inclination, the working diameter of the tool also changes. Variations in the working diameter leads to an unstable cutting speed, affecting the roughness homogeneity of the smoothed surface. This article discusses the effect of changing the cutting speed on the surface roughness in the case of concave and convex surfaces.","PeriodicalId":43118,"journal":{"name":"Hungarian Journal of Industry and Chemistry","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69557354","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}

These results were used to observe whether the ship is expected to decelerate or the change in the draft is likely to cause stability problems. In recent years, the rules concerning the use of inland waterways by recreational crafts have been tightened for environmental reasons. In many cases, these restrictions affect the drive chain, making the workflow of the conversion involved frequent. In this case, it is extremely important for shipowners to know how the draft will change and at what speed the ship will operate after the conversion. This study on a numerical flow simulation provides an excellent opportunity to find out.","PeriodicalId":43118,"journal":{"name":"Hungarian Journal of Industry and Chemistry","volume":null,"pages":null},"PeriodicalIF":0.2,"publicationDate":"2021-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69557516","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}
