CNC carpentry: the 'selfsupportingframework'
Two students working on load-bearing systems in the architecture department at Kassel University, Mischa Proll and Andreas Günther, have taken advantage of the wide range of design techniques available and breathed new life into a one-hundred-year-old construction concept. The traditional reziprocal frame consists of short wooden joists, whose ends are carpentry-joined to a surface structure. With consistant types of profiles, lengths of elements and positions of the knots on the axises, a dome shape is created. The first documenting of such a framework, also called a „mandala roof“, dates back to the 12th century, according to the students' research, when a Buddhist monk by the name of Chogen created designs for temples, whose influence can still be seen today in the architecture of domes in China and Japan. The variation of individual parameters, for instance changing the join between two elements, leads to a change in all the other subsequent joins.
