One piece parallel spring movement has an unique point, a load applied on which makes its carrier move rectilinearly without rotational displacement, or pitch. It is significant to study the effect of errors in dimension of leaf springs, that is, length and thickness, on pitch error which dominates the capability of a movement designed to move with translational motion. Theoretical analysis followed by Finite Element Method (FEM) help the authors make sure the most important thing in this paper as following; As long as both two leaf springs are symmetric in their shape, with respect to a given line, no pitch error is observed, resulting in the carrier being moved with rectilinear motion. The line mentioned above is the one which passes through the midpoints of two springs in the longitudinal direction.
