| Abstract |
The hybrid polishing kinematics machine tool (HPKMT) which is made up of “3 axes
parallel + 2 axes series” is developed with the specially designed elastic polishing tool system for
the polishing operation on the free-form surfaces by using the characteristic of the elastic polishing
adequately by the authors. In order to control the HPKMT effectively, its characteristic of the
kinematics and dynamics need be known deeply. Moreover, the problem of inverse dynamics is the
theory foundation to apply dynamic control of the HPKMT. The analysis of the inverse of
mechanism is the important part in the research of dynamics. On the basis of the differential
equations of flexible multi-body dynamics, this paper discusses on the condition of knowing the
trace, posture and velocity for the end of bodies how to solve the constraint force and constraint
moment of each joint on the 3- PTT parallel mechanism and two-joint series mechanism. |
