The day-to-day use of parallel kinematic machines (PKM) is limited by the size of their five-dimensional working area and position-dependent features. With the conventional hexapod, a structure optimisation does not offer the possibility of overcoming these problems. Three new approaches to machine structures for surmounting these limits are described and evaluated.
