All the teams from the different countries met in the center of Liberec in a small Asian restaurant called Sakura.

On Monday morning we started the meeting at 8:30 at the school. After a short introduction to the students and the teacher we walked around in different departments of the school. We saw the joiner workshop, where students from first and second year made their woodwork products and after this we took a look on the upolstery department to see this interesting work. Tomas explained the machineries in the machinery workshop and explained some safety regulations about the machines.
Then Tomas made a presentation to the use of the Woodwop software which is used as the programming base for their CNC. The students had to make the programming of typical CNC programming like drilling, routing and geometric work and afterwards he gave some tasks with difficulties for the future tasks of wardrobe creations.
After lunch we were treated to an introduction concerning the software SketchUp (STL-file) in order to see how to create a model which should then be used for the creation of the coat rack supports. The teams were divided into four groups to create two very different wardrobes. Now Tomas distributes the drawings and material lists and the trainees bring the laminate panels to the workshop to be cut up. The last two hours of the day the groups were set up and the students coordinated in order to choose and optimize the boards they wanted to use during the next days. The laminate panels were sponsored by a company that no longer needed these panels for their production. This solution is a partial aspect of the `Green Erasmusplus´, so that the school does not have to buy new panels.

On Tuesday, the students started cutting the laminated boards so that they could be machined at the CNC. Meanwhile the other groups carried out the machining programs in Woodwop and the groups took turns with the sliding table saw. At the beginning, some teams had problems programming the manufacturing steps with Woodwop. The teachers and masters then gave assistance. Shortly before lunchtime, the first group does its test on the CNC and had some success. A team checked the precise fit of the holes in the sides and bottoms by inserting the dowels.

On Wednesday morning one of the groups started the edge banding while the next ones continued programming for the CNC as well as drawing the handles in SketchUp if they wanted another model. Some groups continued with CNC machining and after an explanation of the use of the 3D printer, the first coat rack hooks were printed to be used as handles or hooks. After lunch we also had the visit from one of the female colleague from Tomas. She is from the department of interior design and she made a quick presentation from the school activities, concerning interior design, wood design and design of textiles. One of the groups decided to make their own design for the coat hooks. To do this, he used SketchUp and took the opportunity to make a short video about the use of this software with the different subtleties that can be encountered.
At the end of the afternoon we drove to the University of Liberec to visit part of the department that researches prosthetics using 3D printers. The professor, Mr Jan Koprnicky, presented the different manufacturing methods of 3D printers as well as laser cutters or robot arms, which are also used for the production of exo-skeletons.

This morning Tomas showed us the different internal structures that can be used during the realization of 3D printing so that the structure remains as solid as possible at the realization and this with the greatest economy of material. Some groups have fixed the rebated bottoms with spikes and screws.
The two groups with the small carcasses carried out both the gluing and the attachment of the bases and were divided up so that the drawers could be worked on during this time.
The champfers were machined to 45 degrees with a milling machine, and the champfers at the end of the long feet were machined with a circular saw.
The two groups with the drawers still had to make the drawer and attach the mechanical pulls, while the others still had to 3D print the handles and hooks in the meantime.
Two groups with the small bodies took on both the gluing and the attachment of the bases and were divided up so that work could be done on the drawers during this time.
For dinner, the entire group met with the owners of the Tanpa company in the Budvarka restaurant to have dinner together and to discuss the work they had done together over the past few days.

On Friday morning we met once again at 8:15 at school and did some reflecting discussion with students and teacher. Afterwards we worked on the evaluation of the activity by using the MS Teams software with some questions concerning the individual increase of competences during this Liberec activity. We finished with the evaluation of the project and at 1:00 p.m. everybody went home again.
