The development of mechatronic active control system of tool spatial position of parallel kinematics machine tool

The method and the mechatronic system of active control of the dynamic spatial positioning of the executive body of a parallel kinematics machine tool are proposed. By means of geometric modeling, the basic analytical relations that characterize the interconnection between the rods of the mechatronic control system and the power rods of the parallel kinematics machine tool are calculated. The analytical dependencies that characterize errors of the spatial position of the executive body of the parallel kinematics machine tool are set out. The prototype of the mechatronic system of active control of the dynamic spatial position of the executive body of the parallel kinematics machine tool has been manufactured and its presetting and viability checking made. The special equipment to control the exact position of the tool of the parallel kinematics machine tool when it comes to the position is proposed.
