Purpose: The water and electricity (etc.) supply is the main problem that big agglomerations meet, therefore the non-excavation works are developed in areas of high buildings density. Design/methodology/approach: There are many construction solutions of erosion machines that has already been verified in real tests, but the current goal is to develop non – excavation robotized machine. Erosion machines with main dimensions of the tunnels which are: 1600, 2000, 2500, 3150 are design with use of the computer aided methods. Findings: The result is a modeled in I-DEAS advanced graphical program series of types of the erosion machines with two main designs. The assembly models were analyzed: by system analyze (work simulation of the assembly), by strength analyze (Finite element method) and saved in 2D drawings. Research limitations/implications: The practical methodology verification of creating the systematic part family was based on the designed erosion machines series of types. There were developed: the algorithmic selection methods of quantitative construction attributes, the construction similarity method of the erosion machines, variant analyzes in the I-DEAS advanced graphical program, program and relational parameterization [3,7,11]. There will be created manufacturing process of the parts, which allows to verify the technology on the CNC machines. Practical implications: The designed models will be modified and the construction will be consulted with manufacturers and erosion machine users like: OHL ZS a.s. from Brna, Tauber Rohrbau GmbH & Co.KG from Minster. The companies’ acceptance will result in practical verification by JUMARPOL company. Originality/value: The main achievement is the design of a robotized erosion machine to non – excavation works. The designing process was supported by computer aided methods invented on Silesian University of Technology in the I-DEAS advanced graphics program.
