The project in five facts.
Challenge, approach and results.
The diploma thesis addresses the comprehensive process of planning and implementing a technological process for the manufacture of a new product – a gear drum intended for the motor industry. The main objective of the thesis is to emphasise the importance of a well-considered choice of technological process in serial production, as it significantly affects quality, costs and productivity. The procedures, materials, machines and criteria for selecting the technology are described. The concluding chapter of the theoretical part addresses the importance of quality control and the role of the quality department in ensuring compliance of products with technical documentation and customer requirements. The central part of the thesis presents a case study at the company RIEDL PRECISION d. o. o., where a technological process for manufacturing the gear drum was developed.
Problem
The diploma thesis addresses the comprehensive process of planning and implementing a technological process for the manufacture of a new product – a gear drum intended for the motor industry. The main objective of the thesis is to emphasise the importance of a well-considered choice of technological process in serial production, as it significantly affects quality, costs and productivity. The theoretical part presents key production processes, with emphasis on the development of CNC technology – from NC machines to modern CNC systems.
The main types of CNC machines (lathes and milling machines), their characteristics, advantages and areas of application are described. This is followed by the phases of production preparation: receipt and inspection of material, cutting, preparation for machining and grinding as the final operation after heat treatment.
Solution and Method
The procedures, materials, machines and criteria for selecting the technology are described. Special emphasis is placed on CNC machine programming; the basic principles, software packages used and common errors are shown. The selection of appropriate cutting materials and tools according to the type of machining is also addressed.
Results
The concluding chapter of the theoretical part addresses the importance of quality control and the role of the quality department in ensuring compliance of products with technical documentation and customer requirements. The central part of the thesis presents a case study at the company RIEDL PRECISION d. o. o., where a technological process for manufacturing the gear drum was developed. The characteristics of the part, tolerances, requirements for thermal treatment, cost calculations and analysis of process efficiency are provided.
The actual part of the programme for the CNC machine, which is used in the production of the parts themselves, is presented, and through which we can understand how complex the programming of certain parts for production is. This part also represents a large area for all possible optimisations of production time, as through the course of production we learn where in the programme itself it would still be possible to speed something up or, with small measures, ensure better tool durability. Therefore, we also focus on this part when production is already underway.
The conclusion presents a calculation of the viability of serial production and addresses current topics – sustainable development and digitalisation of production. Their role in the transition to Industry 4.0 and the long-term competitiveness of companies is emphasised.
