Workpiece should be limited degrees of freedom to determine ① fully positioned. Were all six degrees of freedom of the workpiece fixture positioning element is limited, and occupies a unique position in the fixture is fully determined, called perfectly positioned. ② not fully positioned. According to the surface of the workpiece to different processing requirements. The number of positioning points of support may be less than six. Some freedom of processing requirements influential, some degree of freedom no effect on the processing requirements, as long as the processing requirements for determining bearing point, you can use less to achieve the positioning element positioning requirements, this localization called incomplete positioning . The next interference in or too positioning must be comprehensive calculation error, clearance and elastic deformation, while according to workpiece machining accuracy requirements in order to make a proper judgment. Broadly speaking, as long as the positioning of the workpiece to make use of accurate positioning and to ensure accuracy, then this positioning is not belonged to locate, you can use.
