Abstract: The article is devoted to the development of the methodology of making solid models of the body of the knife executing body of a new class of mining machinery – a geokhod. The relevance of the topic is formulated and substantiated. The advantages of using a geokhod for formation of a cavity in the underground space in comparison with other types of tunneling equipment have been highlighted. In order to set the goal and objectives, the main types of the knife executing body and the peculiarities of their operation have been considered. Any knife executing body (blade actuator) can be represented as consisting of three elements: the body of the actuator, which is attached to the coupling module with the head section of the geokhod, and the cutting edge. The geometrical parameters of the cutting edge, and therefore the knife body, depend on the force and geometrical parameters of both the actuator and the geokhod. Three variants of constructive design of the knife executing body are distinguished, for which the methods of constructing solid models are developed. The developed methods of constructing solid models allow creating the constructive solutions of the blade actuator of geokhod of different size, which is a prerequisite for developing a parametric model of creating the bodies of the actuator. The constructed models are fundamental for the development of the manufacturing technology of the geokhod's executive body.
