求翻译：而对于数控加工，无论是手工编程还是自动编程，在编程前都要对所加工的零件进行工艺分析，拟定加工方案，选择合适的刀具，确定切屑用量，对一些工艺问题（如对刀点、加工路线等）也需要做一些处理，并在加工过程掌握控制精度的方法，才能加工出合格的产品。是什么意思？

CNC machining, either manual programming or automatic programming, the processing of parts should be before the programming process analysis, the development of processing program, select the appropriate tool to determine the chip dosage on some process issues (such as knife point, processing route,

As for CNC machining, whether it is manually or automatically programd in programming, Programming before the processing of all the parts for process analysis, formulation, and processing programs select the appropriate tool to identify all persons with disabilities, and usage of some process issues

But regarding numerical control processing, regardless of is the manual programming or programs automatically, all must to the components which processes carry on the craft analysis before the programming, draws up the processing plan, chooses the appropriate cutting tool, the definite scrap amount

And for NC processing, regardless of is manual programming also is automatically programming, in programming Qian are to on by processing of parts for technology analysis, developed processing programme, select suitable of tool, determines cut chip dosage, on some technology problem (as on knife poi
