摘要：
Since most machining operations require a maximum of five axes, the tripod design is becoming popular for development of parallel kinematic machines. Combination of a tripod with a gantry system forms a five-axis machine with both large workspace and dexterity. In this paper, a comparative study is carried out on various tripod units proposed in the literature including Tricept, Z(3) Head, Georg V and Parawrist. For this purpose, a parametric model is developed that applies to a class of tripod units. Based on this model, four different types of tripods are compared, and their differences are analyzed.
