大连数控加工零部件的工艺分析，其重要内容有:

1、查抄零部件的图纸是否齐全和正确，分析零件重要表表的精度、表表齐全性、技术要求等在现有出产前提下能否达到。

2、查抄零部件资料的选择是否适当，是否会使工艺变得难题和复杂。

3、审查零部件的结构工艺性，查抄零件结构是否能经济地、有效地加工出来。

The process analysis of Dalian CNC machining parts mainly includes:

1. Check whether the drawings of the components are complete and correct, analyze whether the accuracy, surface integrity, technical requirements, etc. of the main surfaces of the components can be achieved under existing production conditions

Come on.

2. Check whether the selection of component materials is appropriate and whether it will make the process difficult and complex.

3. Review the structural processability of the components and check whether the component structure can be economically and effectively processed.
