“…In particular, we focus on mechanical transmissions, which are widespread systems in industry, from vehicles to renewable energy, and from machine tools to automation and robotics [30][31][32][33]. Many studies focus on transmission machines from multiple perspectives, such as manufacturing and finishing [34][35][36][37][38], or metrology and tolerances [30,[39][40][41], but only a few of them deal with their design knowledge management. The studied subsystems for mechanical transmissions are both designed and manufactured by a leader multinational corporation and are definitely defined mature products with stable technologies.…”

Engineering design is a knowledge intensive activity for both new and mature technical systems, such as mechanical transmissions. However, design knowledge is often transferred with conservative and unstructured approaches, although knowledge management would be of the utmost importance for modern industries. In this work, we introduce a design tool, called design archetype, for collecting and managing knowledge in systematic design processes. The design archetype addresses input design requirements for different design concepts, therefore, improving awareness of the design process by interactively modifying the design solution due to different input requirements. Finally, the design archetype updates the parameters of a first embodiment computer-aided design model of the concept. A method for the development of design archetypes is presented and applied to two case studies of mechanical transmission subassemblies. The results demonstrate the effectiveness of a systematic design method based on design archetypes stored in the company database.

Obtaining a high quality product (filet) is often necessary to effectively separate the soft tissues of fish raw material. An intensive technological process and a number of unfavorable factors can generate the wear of low-stiffness planar industrial cutting blades used for this purpose. The relatively short time of efficient work of the blade causes the production stoppages needed for its exchange, which consequently can inflict significant financial losses. The wear of industrial cutting blades is one of the important and still unsatisfactorily solved problems occurring in the fish and seafood industry, especially in its branches related to fish processing. In this paper, the authors propose an original solution of the above problem by the possibility of renewing the cutting ability of industrial cutting blades by the process of precise grinding realized on the prototype 5-axis CNC (Computerized Numerical Control) grinding machine. The detailed description of a newly designed and constructed technological machine was expanded by the results of tests carried out in industrial conditions. Results of the regeneration of blades at variable parameters of the grinding process (v w = 300-700 mm/min, n s = 38,000 min −1 ) were analyzed on the basis of surface texture measurements by Talysurf CLI 2000 optical profilometer. The surface texture parameter (amplitude, spatial, and hybrid) analysis allowed to determine the most favorable machining parameters for which compatibility of cutting edge geometry was obtained. The proposed solution can be an interesting alternative to other ways of renewing/exchanging industrial cutting blades.

The pursuit to achieve a broadly defined optimisation of the manufacturing processes imposes the use of the increasingly innovative machining methods. The increase of the machining efficiency, assuring a high surface quality as well as precision of dimensions and shapes, necessitates the search for new methods to meet the demanding requirements, apart from the development of materials used for the working parts of tools, wear-resistant coatings or improvement of the cutting tool point geometry. One of the methods to improve forming by machining is the optimisation of the machining strategy during the manufacture of the components having complex shapes. The progress in this field is particularly noticeable along with development of the software for machining on multi-axis machines. This article presents the results of tests for the impact of machining strategy on passive force, cutting torque, material removal rate, topography of the obtained surface and the shape of chip resulting from the aluminium alloy milling. The tests were performed by comparison of the classic strategy available in the NXCAM system to the iMachining technology.
