TEST BENCH AND PROGRAM FOR SIMULATING THE OPERATION AND ACCURACY OF CNC KINEMATIC AXES

Mihai CIUPAN, Claudiu Ioan RUSAN

Abstract


The paper presents a test bench for testing a system of kinematic axes that are part of some technological equipment. It shows the bench development and the calculation algorithm for loading the kinematic axes with equivalent loads to those to which they are subjected during operation in the real machine. The bench consists of a support in which all the motors of the kinematic axes of the machine are mounted and a table that supports the other elements of the control system. Discs and electromagnetic brakes that are mounted on the motors’ shafts ensure loads equivalent to those during the machine’s operation. The loading of the motors with inertial loads and static loads is done by appropriately sizing the inertial discs and the braking factor, elements that result from a program developed by the authors. To optimize the control system of the axes the program calculates the load for variable input data. The bench was actually built and equipped for testing the kinematic axes of a five-axis CNC milling machine for the purpose of testing the machine through several interpolation programs. The advantages of the conducted research are summarized in the paper.
