Precision and energy parameters of the positioned gantry module

Abstract

The course of the positioned gantry module is maintained by a laser instrument. A laser beam generator emitting a vertical beam is placed at the end of the experimental field. A laser beam catcher with photo diodes is mounted on a positioned gantry module replaceable support. Course deviations were assessed in two cases: when laser, straight-course maintaining mechanism was mounted at the end of the spar as positioning trundle: and when it was mounted at the middle of the spar. Furthermore, we estimated how course deviations vary when changing inter-axial distance of laser catcher photodiodes. Electromechanical transmitter was used in the tests. Gantry module is positioned by a special positioning trundle. It is run by a 12V electric motor through a worm sef-braking reduction gear.
