Six positioning of the workpiece (2) the application of the principle of six positioning six positioning principle for any shape of the workpiece positioning are applicable, if contrary to this principle, in the central position of the workpiece with the can not be fully determined. However. When positioning the workpiece positioning six principles, we must utilize the specific processing requirements. T different positioning of the workpiece surface shape is different, the distribution of anchor points will vary, the purpose is to use the simplest method of positioning the workpiece in the fixture to obtain the correct position quickly. Positioning over whether to allow, specific analysis should be performed according to specific circumstances. Under normal circumstances, if the positioning of the workpiece surface is not rough machined surface, or was going through a mechanical process, it is still very rough, this time over the positioning is not allowed. If the positioning of the workpiece surface after the machining, and the size, shape and position of the positioning surface and the positioning element are doing more accurate comparison of finishing, then had only little effect on the position of the positioning of the workpiece surface size, but can be enhanced rigid during processing, then over the positioning is allowed.
