Design and development of compliant mechanism based systems with precision motion are the need of the hour in micro-precision industry. Compliant mechanisms coupled with the proper flexure hinge can provide excellent accuracy contrary to conventional rigid body mechanism. Various design methods are proposed to design a compliant mechanism such as structural optimization technique, Pseudo Rigid Body Model, Inverse Methods and Intuitive methods. Developing a manufacturable monolithic compliant mechanism is highly challenging. In this paper we have attempted a novel approach to design a compliant mechanism with circular based contemporary flexure hinge. The initial design of flexure hinge is designed intuitively and selection of appropriate geometrical parameters of the flexure hinges is another critical task in the design process. The developed hinges are parameterised using the general screening algorithm in ANSYS Workbench to obtain precise dimensions. The initial design of flexure hinge is designed as a curved beam which have fixed centre of rotation during execution. The method is implemented to design a four bar compliant mechanism and compared with the mathematical results. Scott-Russell straight line mechanism is also developed using this approach and verified its effectiveness. Dimensions of the developed hinges are also provided in the paper to enable future researchers to implement and improve the design. © 2017 Elsevier Ltd.
