Utveckling av rotationshuvud till CNC-testbänk

The thesis was written during an internship at ProCom GmbH in Aachen, Germany. It is a project with the goal to upgrade their already existing three linear axis test bench with two additional rotary axes. The task is to either find an already existing solution or to design, manufacture and install a rotary head on the test bench. The test bench is used to simulate water jet, laser and plasma cutting machines and is designed for internal use by ProCom. It is used to test new developed algorithms of their CNC software but also to test newly developed hardware before it is introduced to the market. The test bench has its axis driven by electrical motors and the additional two rotary axes would also be controlled the same way. The test bench is operated without any process force which means that only its own weight will have to be taken into consideration. The background to this requirement of an extra two axis is that customers are starting to demand a five axis control system for their machines and therefore it must be possible to test and verify the software in a realistic environment. This degree thesis is mostly done with design characteristics and concern from the very start with pre studies, explanation of the machine to the very end of the project with a mounted rotary head. Amoung the proposed rotary heads from the pre-studies, two rotary heads were chosen to go further with to be developed, manufactred and installed. With a modular design, to change between the two heads is possible with only minor effort
