| Summary: | 碩士 === 國立中正大學 === 機械工程學系暨研究所 === 101 === The research objective of this thesis is FANUC controller function of the high - speed high-precision interpolation parameters. Analyse the design principle of the interpolation parameters, also use MATLAB software to construct these controller functions. Then, compare experiment and simulation results to verify the design of the interpolation command coincide with the FANUC controller.
The adjustment rule of interpolator parameter is through the simulation system to analyze the influence of the different parameters for the path, according to it caused the command error and the dynamic error to design an error estimation formula, so that the user can get approximate contour error before the actual processing and adjust related parameters to reach the allowable error. Since this part of dynamic model doesn’t consider the current loop, velocity loop and feedforward, it can be easy to find an analytical solution. After adding the complete loop the contour error will be a considerable difference in the corner, and the arc turn straight. In this thesis we through dynamic model to explore the characteristics of this error and compare simulation results with the actual machine path to verify the correctness of the dynamic model. This complete model can predict the actual path under different interpolation controller parameter setting, which is helpful to tuning parameter for the manufacturer.
