Characteristics of production methods for determining the rigidity of the technological system
Incoming article date: 03.10.2017This article is devoted to the review of production methods for determining the rigidity of technological systems based on metal cutting machines. A description of each method, its characteristics, describes the principle of the appearance of elastic strains of technological systems and the possibility of their measurement. For each method, the limits of its applicability and the possibility of using it in different production situations are given. The mathematical dependences are given which can allow the process engineer to estimate the value of the elastic deformations of the technological system and make appropriate adjustments even at the stage of production preparation (for example, to change the trajectory of the tool when writing the control program for CNC machines). A statistical method for determining the rigidity of technological systems is described, the graphical dependence of elastic deformations on cutting forces is given.
