In the article, a practical example of using the Autodesk Inventor Professional iLogic tool for designing self-propelled drilling rigs has been presented. Self-propelled drilling rigs are advanced mining machines with a complex structure. At the design stage, most of the structural changes affect the stability, manoeuvrability and coverage area of the machine. Working on detailed machine models is timeconsuming and unnecessary in the initial phase of the project. Therefore, a parametric 3D model of a two-boom drilling rig has been developed. It enables a quick analysis of selected machine properties depending on a number of significant parameters. The most important dimensions, masses and centres of gravity of each subassembly are entered by transparent editing windows. Next, model tests are carried out taking into account the pass through a face end of a given width as well as the coverage area of a face with specific dimensions. At each stage of model tests, the location of the machine's centre of gravity against the stability triangle background is analysed. In addition, the model allows entering the longitudinal and transverse angles of inclination of the working as well as determining the distance of the centre of gravity from the tipping edge. The model is a practical tool that makes it possible to easily determine the inner and outer turning radius as well as the working area of the machine while constantly controlling its stability. Due to the use of simplified geometry of subassemblies, the changes in parameters result in an instantaneous change of the model and allow a quick analysis of their impact.

Frezujące organy ślimakowe są podstawowymi elementami roboczymi wielu maszyn urabiających. W artykule zwrócono uwagę na różnice w konstrukcji organów ślimakowych w zależności od przewidywanych warunków pracy. Następnie przedstawiono zastosowanie narzędzia iLogic programu Autodesk Inventor Professional do szybkiego tworzenia modeli organów frezujących. Przedstawiono zasadę tworzenia sparametryzowanych modeli i złożeń przy wykorzystaniu elementów programowania w postaci skryptów iLogic. Zaprezentowano gotowy generator organów uwzględniający możliwość określenia wartości wybranych parametrów liczbowych organu: średnicy, zabioru, liczby płatów i podziałki skrawania. Generator umożliwia również wybór rodzaju uchwytów nożowych, typów noży styczno-obrotowych oraz wybór układu nożowego przestawnego lub zgodnego.

The cutting drums are the basic working components of many mining machines. The article focuses on differences in the design of cutting drums depending on the expected working conditions. The further section proposes to use Autodesk Inventor Professional's iLogic Tool for quick modelling of cutting drums. The principles of creating parameterized models and compositions using programming elements in the form of iLogic scripts are presented. The articles presented a ready-made cutting drum generator, taking into account the possibility to determine values of selected numerical parameters of the unit: diameter, swath, number of patches and cutting pitch. The generator also allows you to select the type of pick holders, conical pick types, as well as the choice of pick system for repositioning or matching picks.
