Essay

The subject of the research are parallel structure machines tools of Hexapod type. The research aims to expand the functionality of the hexapod machine tools based on their rational structure and design parameters. Research methods are the basic aspects of analytical geometry, kinematics analysis of spatial mechanisms, theoretical mechanics, machine tool design, robotics, theory of matrices and vector calculus, computer simulation. The thesis is devoted to extending the functionality of Hexapods by identifying their rational structure and design parameters. It is the first time that the terminology was generalized and the classification and structurally modular design of parallel structure machine tools was designed. The system of indicators of motor capacity of Hexapod while moving the executive body along the lines, planes and volumes, is suggested. Analytical dependences of possible movements of the executive body of the Hexapod on modification of its basic structural elements are determined and their influence on the shape, size and volume of working space is stated. The ways to expand the working space of parallel structure machine tools are suggested. Practical recommendations for the design of Hexapods are provided and several designs of Hexapod and kinematic links have been patented.
