Abstract: |
Titanium alloy is difficult to machine because it belongs to special material; while with high requirements of machine precision and surface quality, double cross-ear tie-in is assembly datum of next working order. Cutters, machine parameter, and process plan are reasonably selected through plenty of experiments and researches. Holes are machined first, and then milling is carried out. As a result, tolerance of machining location and dimension is guaranteed, and machining efficiency and quality of production are improved. |
