Abstract Having information about flowers’ mechanical properties and behavior is necessary for designing automatic and mechanized farm equipment. The following properties are included in cutting cellular materials: compression, traction, bending, cutting density and friction. In this research horticultural plant, herb pharmaceutical and nutritive Rose was used and for the first time crush resistance coefficient, mass density module and cutting efficiency of Rose were measured and reported. These properties depend on species, varieties, stem diameter, maturity level, moisture content and cellular structure. In this research the cutting theory and its related equations were used to determine the mass density Module, crush resistance coefficient and cutting efficiency of rose, scientifically called Rosa Damascene Mill, which is a shrub plant belonging to Rosaceae species. Then a completely randomized design with factorial experiment was used to investigate the effect of petal size (a parameter that represents the level of flower growth), the blade state (single and double blade), cutting bevel angle and cutting speed on the mentioned properties. The results showed a significant relationship between cutting bevel angle and mass density module, crush resistance coefficient and cutting efficiency of rose in a level of 5%; as the angle size increased the levels of mass density module, crush resistance coefficient and cutting efficiency of rose increased.
