This paper presents a study of stability of cutting force in the finish milling operations of the

3D complicated free-form surfaces by feedrate optimization. Besides that, the article also introduces the

construction of a measured model and the way of identifying, surveying the cutting force in CNC milling

when applying feedrate optimization.

Keywords: Feedrate optimization, stability of cutting force.
