The cold bulk forming is a technology that is commonly used in many industrial enterprises. Even though nowadays high demands are posed on labour productivity, quality and own production costs, the findings from practice suggest that not sufficient attention is paid to the issue of tool management. Also, theoretical backgrounds and knowledge in this area are not processed in a sufficiently detailed and comprehensive way. This paper deals with the issue of prediction of the wear surface of the forming tools and their subsequent renewal. The research at selected materials was focused on the course of their straining in contact of the blank with the tool in the process of cold bulk forming. The experiments were based on a simple performance of the conventional upsetting test. On the basis of analysis of the results the mechanism of tool wear by abrasion was determined and its impact on the service life time of the tool and also the possibility of influencing the quality of final parts were evaluated.
Currently, companies have been trying to make the use of their technology, manufacturing capabilities and experienced workforce to respond flexibly to market demands. Collecting and processing of all relevant data in the company is one of the key points to which increased attention should be paid so as to maximize the efficient use of own resources and consequently ensure a continuous reduction of production costs. The article deals with the use of burning machines in engineering company. The product range involves the production of burnouts from standard and special materials as well as welded steel parts of structures. The company has long struggled to optimize the material and information flow between particular production operations. This paper was focused on information flow logistics, which proved to be the biggest weakness of the central material preparation department during the bottleneck analysis. The scientific contribution of the resolved issue can be seen mainly in the possibility of interconnecting process analysis and optimization of material and information flows.
The goal of the submitted paper is to implement the principles of TPM and to achieve almost 100% usability of machines, when there will be no failures and unwanted incidents. The effectiveness of implementing the TPM principles has been experimentally verified in an engineering company. Workplaces for the assembly of rails on Unimatic lines were chosen as a pilot workplace. Prior to the implementation of the TPM, analyses of technical downtime and unplanned shutdowns of the manufacturing devices due to failures, unplanned repairs and maintenance were carried out. The resulting analysis concentrated mainly on two main variables-total cumulative technical downtime at individual workplaces and frequency of occurrence of failures in individual sections of the workplaces. The presented approach and the results obtained underline the importance of applying the TPM principles in practice and their indisputable contribution to the ability to increase business performance. The TPM's progressive maintenance management system represents a prerequisite for the reduction of production costs and losses resulting from unscheduled failures now and in the future.
Prototype production is a key element in the process of developing a new product. The prototype is important both being the initial materialization of ideas and intentions related to the way the product is going to be designed, and also for the subsequent assessment of the technological solution. One of the technologies used in prototype production today is 3D printing. One of its advantages is quick adaptation to more complexly shaped prototypes, which makes it possible to come up with products which would be hard or even impossible to make in the past. The increasing availability of 3D printing equipment is making it all the more widely used. This paper was written to demonstrate the principles of the production of auxiliary gauges, which are used to check the dimensions of a more complexly shaped prototype. The possibilities of using 3D printing technologies in the conditions of an engineering company are also discussed. The conclusion of this paper focuses on the possibilities of integration between modern and classic technologies in piece and custom production.
Many companies have started using dynamic simulation as full support for their own optimization team to optimize business processes. The 3D visualization can facilitate understanding of the links among processes and their connections. It can significantly contribute to its appropriate implementation, which aims at saving costs, simplifying processes, introducing new or innovated processes, etc. Application field is not significant for the 3D visualization. Predictive simulation can be applied in any process, from storage, logistics, handling, through production line optimization to distribution. The submitted paper deals with the optimization of the production process regarding the reduction of handling demands for the company in the automotive industry. Businesses are currently facing an issue of handling complexity, which has a relatively high cost, depending on the amount of unnecessary and chaotic trips within production processes. It is necessary to modify the charging method in any change of production. This is connected with an increase of non-productive rides. The article introduces the possibility of a variant solution with the possibility to use dynamic simulation as a powerful tool for the process optimization.
