EXPERIMENTAL INVESTIGATION OF HIGH PRECISION XY MECHANISM

This paper discusses static, dynamic characteristics of the XY Mechanism. It offers zero backlash, friction free motion and high order repeatability. Flexure mechanisms are used in high precision applications for compact design in nature. The merit of using flexure mechanism is single monolith. The paper discusses different design of flexure mechanism using DFM. XY Mechanism consists of actuator (VCM), optical encoder, DAQ dSPACE DS1104 R & D Controller Board. XY Mechanism is manufacture on Wire EDM machine and integrates with dSPACE DS1104. Experimentation is carried out on mechanism and parameters are estimated which have close match with FEA analysis. Frequency response of the system and experimental transfer function is identified.
