A method for the design of a technology for the abrasive waterjet cutting of materials is based on the determination of the constant of cuttability of materials using an abrasive waterjet K_awj according to four different versions. Version A, where three deformation parameters are measured on the test cut/sample, namely selected depth h_x [mm], local roughness Ra_x [μm] at depth h_x and local deviation of the cut trace from the normal plane Y_retx at depth h_x. Version B, where merely two deformation parameters are measured, namely the reference depth h_et [mm] and deviation of the cut trace from the normal plane Y_retx [mm] or, according to version C, where one parameter is mearured, namely either the ultrasonic wave speed v_LUZ [m · s^–1] or Young's modulus E_mat [MPa]; K_awj being calculated from relevant deformation parameters. The last option is version D, where the design of the whole technology is carried out by calculation of K_awj according to the Young's modulus E_mat or according to the ultrasonic wave speed v_LUZ of the cut material.
