operation creates plane surfaces. Other geometries can also be created by milling machine. Milling operation is considered an interrupted cutting operation teeth of milling cutter enter and exit the work during each revolution. This interrupted cutting action subjects the teeth to a cycle of impact force and thermal shock on every rotation.
This paper presents an improved cutting force model for circular end milling process based on the typical linear milling force model. The curvature effects of tool path on chip thickness as well as entry and exit angles are analyzed, and the cutting force model of linear milling process is then corrected to fit circular end milling processes.

Aug 25, 2011 · This paper is the latest of a continuing series on the subject of selfexcited machine tool chatter. The representation of the metal cutting process as required by the previously developed closedloop chatter theory is extended to oblique cutting with tools of practical shape and geometry.
Artificial granite material has been used for construction of the highprecision machine due to superior damping ability. However, its lower material stiffness also lessens the appliion in fabriion of the machine tool. The purpose of this study was therefore aimed to verify the structure performance of the machine tool reformed with artificial granite material, instead of the casting iron.
