The Bachelor thesis deals with the issue of parametric milling of finger joints used in furniture manufacturing. The thesis is divided into four parts. The first part is devoted to describing the state-of-the-art of the issue and defining the processes of programming and the factors affecting the production exactitude. Moreover, the properties of material used as well as properties of self-locking joints are given in this part. In the second part, the aim of the Bachelor thesis is set. The third part is focused on selecting the material, establishing the methodology dealing with own trajectory milling associated with the experiment. The thesis provided the summary of literature and research studies aimed at the similar issue. In the fourth part, the experiments are described and the results of individual studies are compared. Finally, the estimated exactitude of the work piece is defined.
