Integrated Geometric Errors Simulation, Measurement and Compensation of Vertical Machining Centres

This Paper presents research on geometric errors of simulated geometry which are measured and compensate in vertical machining centres. There are many errors in CNC machine tools have effect on the accuracy and repeatability of manufacture. Most of these errors are based on specific parameters such as the strength and the stress, the dimensional deviations of the structure of the machine tool, thermal variations, cutting force induced errors and tool wear. In this paper machining system that simulates the dimensional and geometric errors of three real axes describes milling machining. In order to validate the system closed loop feedback system is provided which rectify as well as compensate the errors in order to present the reliability and accuracy of the software. An experiment has been conducted on a 3axis vertical CNC milling machine; the results show that this method is efficiently effective and applicable on any multi axis machining operation.International Journal of Advanced Mechanical Engineering, Volume 4, Number 1 (2014), pp. 21-2
