Audity wewnętrzne a system zarządzania jakością

Czytaj za darmo! »

Audit nie jest nalotem ani łapanką.Wewnętrzne audity jakości są jednym z podstawowych działań wymaganych w systemach zarządzania jakością [1]. Są one realizowane według zasad określonych w normie ISO 19011 [2]. Chociaż norma ta nie jest obowiązkowa do stosowania przez firmy posiadające certyfikat systemu zarządzania jakością, to jednak zasady w niej zawarte są zalecane dla zapewnienia skutec[...]

In a global business environment, manufacturing companies face several important challenges. Among them, mass customization (MC) plays an important role, since it offers new potential for acquiring new markets and generating benefi ts for itself and participating companies. MC is likely to be a future trend of the business strategy development. In this context, questions arise regarding what characterizes the current trends of MC, how it differs from previous manufacturing strategies, and what will be the future of manufacturing when it takes a global approach. Providing accurate answers is not easy and requires considering at least two aspects of the term. If we comprehend MC as a marketing and manufacturing technique that combines personalized customization and mass production, then we can see manufacturing and marketing perspectives in determining optimal overall strategies for companies. The fi rst view regards the world of manufacturing that is changing as it follows the world of technology. Technological changes are driven by many factors such as safety and environmental standards, social demands, the diffusion of innovation, etc. Technology is changing very rapidly and the newest technological developments are reshaping the manufacturing sector in its original form. For example, additive manufacturing (AM), cloud computing, radio frequency identifi cation, fi fth generation (5G) wireless systems, and the Internet of Things (IoT) are only a few of the new technologies that are driving a paradigm shift in manufacturing. The umbrella term for this new wave of the so-called smart manufacturing is European Industry 4.0. This promising concept includes, among others, important attributes such as machine connectivity, data gathering and the analysis for productivity improvement and software tools for digitizing the manufacturing world leading to smart factories. Although till now still not many companies declare that the[...]

PULL-OFF TEST OF ADHESIVE JOINTS BASED ON POLYESTER-GLASS LAMINATE AND ALUMINUM ALLOY DOI:10.15199/160.2019.4.1

Adhesive joints are becoming more and more popular and they are a particularly attractive method of joining construction materials with different mechanical and functional properties, e.g. metal and composite elements [1, 2]. In work [4] a review of conditions generating the demand for adhesive joints was presented. In construction, adhesive joints are used, for example, to joint composite laminates with steel beams [8]. For joining metal and composite elements, adhesive joints are also used in aircraft constructions [5], in turbine production [10] or in pipe joints [11]. A special solution in which adhesive joints are used is the production of hybrid composites, in which metal layers, e.g. aluminum foils, are alternately joined with a composite material to form a laminate with unique properties [9]. Previous studies of adhesive joints based on polyester-glass laminates and aluminum show that in addition to the identified problems defined for adhesive joints, there are new, associated with limited interlayer strength of the laminates. A non-uniform distribution of stress in the adhesive joints and stress concentration effects at the ends of their overlap cause the pull-off and peeling phenomena not only in the adhesive, but also in the joined composite element. Consequently, as a result of the joint load, not only the joint is damaged, but very often also the composite material as a result of exceeding the adhesive interlayer strength of the laminate. These A b s t r a c t: Adhesive joints are widely used in various industries to join different materials. They always have to meet specific requirements for joint strength or durability. The article presents the results of research on the problem of joining elements made of aluminum alloy and polymer composite material present in the railway industry. The tested adhesive joints combine EN AW- 5754 aluminum alloy (AlMg3) with a polyester-glass laminate. Three types of adhesives we[...]
