A novel orthogonal 5-DOF parallel gasbag polishing machine is proposed

and the kinematic transmission equations of the 5-DOF parallel gasbag polishing machine is derived in closed forms based on kinematic analysis

then the kinematic transmission performance evaluation indices are defined based on the kinematic transmission equations and discussed in detail

at last

by using the MATLAB

the distribution of the evaluation index are drawing on the workspace respectively

which can provide theoretical base for the applications of the 5-DOF parallel gasbag polishing machine.The novel 5-DOF parallel gasbag polishing machine can be used as the precision platform in which the requirements for high stiffness

high accuracy and good technological efficiency.
