In this thesis, we worked on the development of an accessory for a kitchen machine that can cut different types of fruit and vegetables. First, a brief overview of the basics of the lead screw assemblies and spur gears, which are the essential components of the kitchen machine accessory, was carried out. We also presented the VDI 2736 recommendations for the evaluation of thermoplastic spur gears and the guidelines for the design of injection molded products. Next, torque measurements were performed during cutting on an existing accessory with a similar operating principle. The results of the measurements were considered as input data for the dimensioning of the components. A strength calculation of the lead screw assembly and an evaluation of the gear pair according to the VDI 2736 recommendation were carried out. The housing was designed in accordance with the injection molded product design guidelines. On part of the housing, a topology optimization of the reinforcement ribs layout was performed using HyperMesh. Finally, the final shape of the optimized housing part was validated by structural analysis using the finite element method.
