What are the advantages of computer gong processing? What is the choice of positioning reference for computer gong processing center?

How do you choose the positioning datum of CNC computer gong machining center? Because the positioning of CNC computer gong machining center is also a weak aspect of many users in the machinery industry, what are the selection of positioning benchmarks for CNC computer gong machining center? What are the positioning benchmarks for CNC computer gong machining center?

1. Three basic requirements for benchmark selection:
①. The selected datum should be able to ensure accurate positioning of the workpiece, convenient and reliable for loading and unloading.
②. The calculation of the selected datum and the size of each processing part is simple.
③. Guarantee processing accuracy.
2. The best clamping position of the workpiece on the worktable of the machine tool: The clamping position of the workpiece should ensure that the workpiece is within the processing stroke range of each axis of the machine tool, and the length of the tool should be shortened as much as possible to improve the processing rigidity of the tool.

Three, 6 principles for selecting positioning benchmarks:
①. Try to choose the design datum as the positioning datum;
②. When the positioning datum and the design datum cannot be unified, the positioning error should be strictly controlled to ensure the machining accuracy;
③. When the workpiece needs to be clamped and processed more than twice, the selected datum can complete the processing of all key precision parts in one clamping and positioning.
④. The selected benchmark should ensure that as much processing content as possible is completed;
⑤. During batch processing, the part positioning datum should be as close as possible to the tool setting datum established in the workpiece coordinate system;
⑥. When multiple clamping is required, the benchmark should be unified.
