Outline of Final Research Achievements

This study concerns a development of the system which applies "predictive and compensation control" with the results to multi-axes processing. Moreover the system realizes the multi-axes processing that is able to control high- speed and high-precision by "geometric interpolation" and "prediction control". To construct prototype systems, three functions, as follows, are developed. First is the geometric interpolation that generates servo data. Second is the drive function that moves multi-axis machine motors according to servo data. The other is the measurement function to evaluate precision. However, the constitution of multi-axis machine tool that introduced last year is not adapted to the prototype we developed. Because the prototype system requires an improvement, the evaluation of this prototype is required and not brought to a conclusion. The geometric interpolation function is developing and it is improving now, the evaluation of this system is required as soon as possible.
