The article presents the methodology and results of measurement of the unitary energy in cutting black radish. The values of the unitary energy of cutting the root parenchyma of black radish sampled in several areas were analysed. To compare the values of the unitary cutting energy related to the differences in the structure of the black radish root, the samples were cut at the longitudinal and transverse orientation of the fibres relative to the movement of the working tool. The cutting process was carried out using knives with a sharpening angle of 5°, 10°, and 15° and cutting velocity values of 100 mm·s-1, 200 mm·s-1, 300 mm·s-1, and 400 mm·s-1. The results obtained were subjected to mathematical analysis in Statistica 8.0 software. The statistical analysis showed a significant correlation between the value of the unitary energy and sampling site, the knife sharpening angle and the velocity of knife movement. The highest value of the unitary cutting energy was obtained at a sharpening angle of β=15° and the lowest value was observed when the knife with the β=5° sharpening angle was used. The unitary cutting energy decreased with the increase in the knife movement velocity.
