5. Conclusions
In this paper, a method is proposed to build a CPS model of a CNC machine tool work process based on instruction-domain electronic data analysis. Several case studies of intelligent-machining application are conducted. The method has the following features.

The CPS model of a CNC machine tool work process establishes the relationship among work task WT, manufacturing resources MR, and operation status data Y in CS: Y = f (WT, MR).
