For CNC computer gong machining center positioning datum selection, how do the relatives choose it? Because CNC computer gong machining center positioning in the machinery industry is also a lot of user knowledge is weak in terms of, then CNC computer gong machining center positioning benchmark selection what are they?CNC computer gong machining center positioning benchmark what are the points?
I. Three basic requirements for choosing a benchmark.
①. The selected benchmark should be able to ensure accurate positioning of the workpiece easy and reliable loading and unloading.
②. The selected benchmark and the size of each processing part is simple to calculate.
③. Ensure machining accuracy.
Second, the best clamping position of the workpiece on the machine table: workpiece clamping position should ensure that the workpiece in the machine tool within the range of the machining stroke of each axis, and make the length of the tool as short as possible to improve the rigidity of the tool processing.
Third, the selection of positioning benchmark 6 principles.
①, try to choose the design reference as the positioning reference.
②, positioning datum and design datum can not be unified, should strictly control the positioning error to ensure processing accuracy.
③, the workpiece needs more than two clamping processing, the selected benchmark in a clamping positioning can complete all the key precision parts of the processing.
④, the selected benchmark to ensure the completion of as much processing content.
⑤, batch processing, part positioning benchmark should be as far as possible with the establishment of the workpiece coordinate system of the tooling benchmark overlap.
⑥, need for multiple clamping, the benchmark should be unified before and after.
