The paper considers the assessment of the interaction of a spatially oriented knife of a bulldozer blade with the working environment, which was carried out on the basis of a one-factor experiment using high-tech measuring and recording equipment, which allowed to quickly obtain accurate results from the primary data. Oscillogram processing consisted of determining the average maximum ordinate of the cutting force P and finding its value. Thanks to the use of the designed and developed high-precision control system for feeding and transverse movement of the working body and high-tech measuring and recording equipment, which allows to quickly and without repetition obtain sufficiently accurate estimates of the interaction of the spatially oriented blade of the bulldozer blade with the working environment from the primary data and made it possible to process them using modern software, which eliminated the time-consuming data processing process. This, in turn, made it possible to minimise the number of measurements of the cutting force at a given accuracy and reliability of the test results with a data probability of 0,9 to 0,95.References
