摘要

工具機終端應用大致上可分為高移除量的粗加工製程與要求精度與表面粗糙度的精加工製程，機台本質即為一機電整合系統，包含了機台結構與伺服驅動控制模組，因此要藉由CAE分析技術來模擬機台動態特性，就需整合機台結構與伺服驅動控制模組，建構完整機電整合多體動力學數位模型，其中每一個子系統模型的正確性，均會影響到整機動態模擬分析的結果。本文將針對精加工問題進行探討，首先鑑別伺服馬達的控制迴路模型，並建立機台結構動態響應特性，最終將控制與機構進行整合來進行路徑軌跡的模擬。

The major end-use applications of machine tool are rough processing for high performance and finishing processing for high accurate and high quality. Machine tool is a mechatronic system in nature which including structures and servo-drive controller. A correct structure model and servo-drive control model are needed for building accuracy multibody dynamic mechatronic digital model that can be used in analyzing machine dynamic behavior by CAE technique. Any sub-system model's correctness will affect the accuracy of total system's model. The correctness of interface's model between each sub-system will also affect the accuracy of total system's model. This paper will discuss the problem of finishing processing. First identify the servo motor control loop model and establish the dynamic response of machine structure. Finally, combining servo-drive control model and structure model to carry out the simulation for path error.
