THE DESIGN OF PARALLEL KINEMATIC MACHINE TOOLS USING

However, the design of a parallel kinematic machine tool (PKMT) is a hard task that requires further research studies before wide industrial use can be expected. Many criteria need to be taken into account in the design of a PKMT. We pay special attention to the description of kinetostatic criteria that rely on the conditioning of the Jacobian matrix of the mechanism. The organisation of this

Desktop 3-axis parallel kinematic milling machine

Many different topologies of parallel mechanisms with 3–6dof, including hybrid parallel mechanisms, have been used [2, 3]. Compared with conventional machine tools, parallel kinetic machines (PKM) have many advantages, e.g., higher stiffness and higher ratio of force to weight. This is regarded as a revolutionary concept for machine tools.

Kinematic Analysis of a New Parallel Machine Tool: the

Parallel kinematic machine tools attract the interest of more and more researchers and companies. Since the first prototype presented in 1994 during the IMTS in Chicago by Gidding&Lewis (the Variax), many other prototypes have appeared as could be seen during the last World Exhibition EMO’99 which was held in Paris in May 1999. A recent comparative study shows that certain parallel kinematic

Optimization Possibilities of Parallel Kinematic Machine

Machine tools with parallel kinematic structures (PKM) are known as 3- or 5- axis machines, which are typically used in drilling and milling work, but PKMs can also be employed in laser machining or high pressure jet cutting. This type of machining necessitates high precision requirements similar to that attained with conventional machine tools. Particular attention must be paid to the mastery
