This paper describes the experience of the Laboratory of Micromechanics and Mechatronics in the production of low cost micromechanics. A case of study is discussed and explained. The importance of applying simple mechanisms and high level control systems is presented. The basic elements and components needed to develop a high resolution micromachine tool are presented. This case of study is a MicroMachine Tool of 800nm of resolution in its three translational axes. Every single axis is able to move along 20mm. The configuration of the axes is not conventional, thanks to the use of parallel elements that results in semi circular movements.
One of the most important stages in the analysis of any mechanical model is to establish and find the solution of dynamical equations. Analytical Mechanics has developed a wide range of methods for obtaining equations of motion of coupled rigid body systems that represent a mechanical model. How to use the principles of the mechanics of setting up dynamic equations leads to different forms of presentation. This circumstance is often used to obtain a special form of the equation, which simplifies the study of the dynamic properties of interest to the mechanical model. In this paper we use the method Kharlamov 1 and the theorems of classical mechanics for the specific study of a parallel system, which represents a schematic model of parallel micro-manipulators, such as a finite set of bodies Si (i = 1 , ..., n). This model is to show a design of a parallel micro-platform, that it simulates the virtual movements of a flight simulator, it has three degrees of freedom, and it is a lightweight design. One of the innovations presented in this design consists of the application of a lever mechanism for the transmission of the movement.
