Challenge, approach and results.
The diploma thesis addresses the design concept, calculation and optimisation of CNC machining of the gearbox housing and its components. The results demonstrate how an optimised approach to design and machining can achieve a technically refined, cost-effective and durable gearbox solution tailored to the specific requirements of shipbuilding. The conclusions are useful as guidelines for further product development and improvement of production processes.
Solution and Method
The diploma thesis addresses the design concept, calculation and optimisation of CNC machining of the gearbox housing and its components. Gearboxes are key elements in power transmission between main engines and propulsion systems of ships. Particular emphasis is placed on the development of the housing and internal components, which must ensure high strength, reliability and corrosion resistance.
At the same time, they must maintain minimum mass and enable economical production and easier product exploitation. Within the diploma thesis, key design calculations are carried out, including determination of mechanical properties of the material, load analysis and determination of required gearbox dimensions. Modern software packages for modelling are used (Solidworks and AutoCad).
In addition to design, great emphasis is placed on optimisation of the CNC machining process. Machining strategies, selection of appropriate tools and machine settings are studied, enabling shorter machining time, cost reduction and improved surface quality. The optimisation takes into account the specific properties of the housing material, such as hardness, wear resistance and weldability.
Results
The results demonstrate how an optimised approach to design and machining can achieve a technically refined, cost-effective and durable gearbox solution tailored to the specific requirements of shipbuilding. The conclusions are useful as guidelines for further product development and improvement of production processes. Various materials used in the manufacture of gearbox housings in shipbuilding are analysed, taking into account factors such as strength, corrosion resistance and machinability.
A comparison of materials is presented in terms of their economic efficiency and usability in industrial applications. Machining of the gearbox housing requires the use of specific tools for precise cutting and forming. This work examines different types of cutting tools and their optimisation according to specific machining requirements, such as material type, housing shape and size.
Various machining processes are investigated, including cutting, drilling, grinding and surface treatment, as well as how to optimise these processes using modern CNC technologies. The use of different machining strategies is presented, such as progressive cutting, tool path optimisation and reduction of machining time through greater automation and computer planning.
