Abstract: The subject of this paper is the design of a new concept of modular parallelmechanisms for three, four or five-axis machining applications. Most parallelmechanisms are designed for three- or six-axis machining applications. In thelast case, the position and the orientation of the tool are coupled and theshape of the workspace is complex. The aim of this paper is to use a simpleparallel mechanism with two-degree-of-freedom (dof) for translation motions andto add one or two legs to add one or two-dofs for rotation motions. Thekinematics and singular configurations are studied for each mechanism.
