Abstract
The paper presents the issue of computer modelling of the surface after machining. The modelowanie_skr program, whose operation is based on subtracting simple geometric solids from a flat surface to create a given structure, was used. A front-milled surface was modelled, and two types of wavelets were placed on it; then the obtained surface image and parameters of the 3d structure were compared. The comparison was extended to cases where the surface disturbance occurred. Four types of disturbances, with a variable percentage, were distinguished. Conclusions determined the usefulness of selected wavelets in computer modelling and changes of the surface along with the application of disturbances and wavelets on it.
