Abstract—When performing works on improvement in the city line, a variety of road and construction machines are used, however, in case of inaccurate operation of such machines, previously laid communications can be damaged, which leads to disturbances in the operation of urban systems affecting thousands of people. In this article estimation of the accuracy of the position of the cutting edge of the bucket is given considering the temperature expansion of the links, the variable cutting forces, the delay of the hydraulic drive, gaps and elastic deformations in kinematic pairs. Based on the calculations carried out, recommendations are proposed for developing methods to improve the accuracy of digging.
