The project in five facts.
Challenge, approach and results.
The diploma thesis addresses the development, implementation and optimisation of clamping fixtures within the production processes of Mega-Metal, d. o. o. The results of implementing the new clamping fixture show significant time savings. The clamping time was reduced from 30 to 20 minutes, representing a 33.3% saving, whilst the machining time decreased from 3 hours to 2 hours and 40 minutes, representing an 11.1% saving.
Solution and Method
The diploma thesis addresses the development, implementation and optimisation of clamping fixtures within the production processes of Mega-Metal, d. o. o. The introductory section includes the definition of the research field, purpose, objectives and basic propositions with key assumptions and limitations. This is followed by a presentation of the company, including its organisational structure and technological equipment of the machine park dedicated to mechanical metal processing.
The theoretical section of the research encompasses a detailed analysis of the development of clamping fixtures through various historical periods, from the first mechanical solutions to modern high-tech systems. A classification of clamping devices is described, which includes manual, machine, hydraulic, pneumatic, magnetic, vacuum, modular and quick-change systems. An analysis of the existing situation is carried out, technical limitations are identified and specific proposals for improvements are provided based on the identified shortcomings.
The practical section of the research comprises the development, design and manufacture of an optimised clamping fixture using SolidWorks and Mastercam software. The technological manufacturing process is described in detail, including welding, vertical turning, milling, drilling and thermal and chemical treatments, with the aim of improving the mechanical properties and durability of the clamping fixture.
Results
The results of implementing the new clamping fixture show significant time savings. The clamping time was reduced from 30 to 20 minutes, representing a 33.3% saving, whilst the machining time decreased from 3 hours to 2 hours and 40 minutes, representing an 11.1% saving. Taking into account the weekly production of four pieces, this represents an annual saving of 75 hours, equivalent to almost 10 working days.
The concluding section of the diploma thesis addresses long-term maintenance and possibilities for further system upgrades that could further improve efficiency. The approach to optimising clamping systems enables greater company competitiveness, lower production costs and improved quality of final products, which is crucial in modern industry. In addition to the analysis of development and classification of clamping devices, it also includes four confirmed hypotheses that emphasise the importance of analysis in reducing errors, optimisation for faster clamping, adaptability of fixtures for use on different machines and regular maintenance to ensure sustainability.
