About the project

Challenge, approach and results.

The diploma thesis addresses the use of collaborative robots in production processes with emphasis on the integration of the Hanwha HCR-5A collaborative robot with the DOOSAN Puma TT 2100Y CNC lathe. The purpose of the work is to examine the impact of automation on the optimisation of mechanical machining, particularly from the perspective of increasing productivity, improving quality, reducing the physical burden on workers and economic effects. The theoretical part presents the key characteristics of collaborative robots, their historical development, advantages and limitations, and a comparison with traditional industrial robots. The practical part of the diploma thesis includes a description of the existing working method on the CNC lathe, planning and implementation of robot integration, and analysis of results. Special attention is given to examining the impact on productivity, quality, safety and worker ergonomics.

Problem

The diploma thesis addresses the use of collaborative robots in production processes with emphasis on the integration of the Hanwha HCR-5A collaborative robot with the DOOSAN Puma TT 2100Y CNC lathe. The purpose of the work is to examine the impact of automation on the optimisation of mechanical machining, particularly from the perspective of increasing productivity, improving quality, reducing the physical burden on workers and economic effects.

Solution and Method

The theoretical part presents the key characteristics of collaborative robots, their historical development, advantages and limitations, and a comparison with traditional industrial robots. Emphasis is placed on the technical requirements for integration, safety aspects and the adaptability of collaborative robots in production environments. Special attention is given to the process of integrating a collaborative robot into an existing production process, addressing key challenges such as selecting an appropriate installation location, ensuring safe collaboration with operators, and optimising the robot path to achieve maximum efficiency.

The need to adapt software and interfaces for seamless communication between the robot and the CNC machine is also presented. Additionally, the research addresses the complexity of programming and the flexibility of collaborative robots compared to conventional robotic systems.

Results

The practical part of the diploma thesis includes a description of the existing working method on the CNC lathe, planning and implementation of robot integration, and analysis of results. Special attention is given to examining the impact on productivity, quality, safety and worker ergonomics. The impact of automation on reducing human errors and improving process reliability is highlighted.

The economic analysis addresses the costs of implementation and the long-term return on investment. A comparative analysis of manual and automated production is carried out. The study also includes a calculation of return on investment (ROI) and an assessment of the payback period.

The work concludes with a summary of key findings, recommendations for further research and possibilities for improvements and upgrades, with the aim of achieving even greater efficiency and sustainability of automated solutions in industry.
