Positioning of computer gong machining 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 fo

Computer gong processing, what are the benefits of computer gong processing?

   1. Three basic requirements for selecting benchmarks:

  ①. The selected datum should be able to ensure accurate positioning of the workpiece, convenient and reliable loading and unloading.

  ②. The selected datum and the size calculation of each processing part are simple.

  ③. Guarantee machining accuracy.

   2. The best clamping position of the workpiece on the machine tool table: 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.

  Computer gong processing, what are the benefits of computer gong processing?

   Three, 6 principles for selecting positioning benchmarks:

  ①, try to choose the design datum as the positioning datum;

  ②. When the positioning reference and the design reference cannot be unified, the positioning error should be strictly controlled to ensure the processing 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 standard should be unified.
