Error modeling and sensitivity analysis of a 3-P(Pa)S parallel type spindle head with parallelogram structure

The 3-P(Pa)S mechanism, based on the 3-Prismatic-Rotational-Spherical (PRS) mechanism, but with three of its revolution joints and passive links replaced by parallelogram structures, provides improved stiffness and better constraint of undesired Degree of Freedom (DOFs). The general method to establ...
