Sarvey on Key Technology and Present Status of Parallel Kinematics Machine Tool

With the development of the society,the parallel kinematics machine tool technology is researched as a hotspot in numerical control field rapidly.It has widely application and broad development foreground.A brief survey on the research status and key technology of parallel kinematics machine tool such as model of numerical control system by real time,positive and negative solutions of mechanism position and movement trajectory plan were given,and some possible problems and solution approaches of the future development were presented.
