Design and Manufacturing Technology of a Drawing Tool

This diploma thesis presents the entire process from design to the manufacture of the final product.

Solution and Method

This diploma thesis presents the entire process from design to the manufacture of the final product. The company Kovinarstvo Peter Porenta, s. p., with the purchase of a CNC milling machining centre in April 2023, focused on its own tool production. This step created the need for the development of new machining technology adapted to specific materials.

The methods include description, compilation, comparative method, deduction and synthesis. The objectives of the diploma thesis are: optimisation of tools for the manufacture of final products, reduction of production phases and research into different metal machining technologies. Particular emphasis is placed on adapting the technology according to the properties of the materials used.

The 3D modelling of the tool using SolidWorks is described in detail, including specifications of individual components such as base plates, die, slider, outer knife and other parts. Emphasis is also placed on adapting the design for two types of tools, for a drawing tool and for a blanking tool. The selection of materials for the tools is based on their physical and economic properties.

Tool steel 1.2379 is used for key components due to its high hardness and wear resistance, whilst other components are made from different materials such as aluminium 5083, due to specific properties, namely low hardness and corrosion resistance. Different technologies are described: turning, milling, drilling, grinding and wire erosion. Each technology is selected according to its suitability for individual aspects of tool manufacture.

The practical application of different technologies is demonstrated in the manufacture of tools. Emphasis is placed on the use of the CNC machining centre and on the combination with other machining techniques such as turning and grinding, and on solving specific challenges such as jamming of parts. The diploma thesis includes tool inspection, assembly, production of inspection drawings, mounting on the machine and initial tests.

Corrective measures that were necessary due to problems in the process are highlighted. The time, financial and quality aspects of the choice of technologies are analysed. Emphasis is placed on efficient utilisation of the machine park, cost optimisation and ensuring product quality.

The diploma thesis demonstrates the importance of planning, analysis and communication in tool manufacture. The project has provided valuable experience and highlighted the role of CNC technology in modern production.
