③ due to positioning. Processing requirements should be limited in accordance with the freedom to vote is restricted called positioning pots positioning. Less positioning is not allowed due to the positioning of + pour not guarantee processing requirements. Such as through slots on the milling parts, it should be limited to three degrees of freedom in order to ensure parallel processing requirements and the size of both the A side and the bottom surface; two degrees of freedom should be restricted in order to ensure parallelism and size groove side and B side of 30mm ± o lmm two processing requirements; freedom does not affect the pass grooving, you can not limit. 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.
