ANALYSING KINEMATIC AND DYNAMIC PROPERTIES OF A MACHINE TOOL ALONG CURVED TOOL PATH IN HIGH MACHINING

Abstract

Abstract: The relationships between geometrical properties of cutter path, including position, tangent and curvature, and kinematics and dynamics of a machine tool including feedrate, acceleration and driving force, are analyzed in detail. The analytical method of obtaining maximum safe feedrate along a curved cutter path with driving force and acceleration constraints is also introduced. The result shows there are great influences of geometrical properties of cutter path on the kinematics and dynamics of a machine tool.

Key words: CNC machine, Dynamics, Feedrate, High speed machining, Kinematics
