大連數控加工零部件的工藝分析，其主要內容有:

1、檢查零部件的圖紙是否完整和正確，分析零件主要表面的精度、表面完整性、技術要求等在現有生產條件下能否達到。

2、檢查零部件材料的選擇是否恰當，是否會使工藝變得困難和復雜。

3、審查零部件的結構工藝性，檢查零件結構是否能經濟地、有效地加工出來。

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.
