This invention relates to the field of milling processes, specifically a general process for
machining aircraft engine mounting clamps and bases. It includes the following steps: S1, blanking; S2, cubic milling; S3, drilling and reaming process holes and clamping holes; S4, CNC roughing: roughing is performed using an indexable
milling cutter, with a
cutting allowance reserved and proper datum surface positioning; S5, CNC finishing: during finishing, except for necessary
machining allowances reserved on the web surface, spherical surface, and lug hole surface, all other structural features are machined in
one pass; S6, blanking by milling; S7, heat treatment; S8, semi-finish
grinding; S9, boring; S10, fitting by fitter; S11, finish
grinding; S12, turning; S13, measurement and inspection of parts; S14, disassembly of parts; S15, heat treatment; S16, mechanical inspection. This invention can shorten the manufacturing cycle and reduce production costs.
