It wants cutter lifting evacuation not brush up against technique at six when enclosing contour line and casts platform；
[8] convex surface described in finish-milling:
According to above-mentioned operation [7], rough mill, convex surface described in half finish-milling and finish-milling, in order to guarantee given design parameter when processing,
The muscles and bones position is supported by above-mentioned special tooling, is occurred to play knife to prevent the muscles and bones position or is led to optical window skeleton
Precision castings are deformed；
[9] five described in finish-milling at edge in window:
According to above-mentioned operation [8], rough mill respectively, five described in half finish-milling and finish-milling at edge in window, two after finish-milling at scalariform it is infrared
Receive window, the dimensional accuracy and surface roughness of four horn shape radar detection windows and triangular shape target observation window symbol at two
Close given design parameter；
[10] technique casts platform at removal six:
Casting platform by technique at finish-milling removal six again after the completion of above-mentioned operation [9] makes it keep same flat with the outer ring contour line
Face；
[11] subsequent processing:
The sharp edge burr remained to above-mentioned each process is removed, then meets given design through window at five described in three Coordinates
It is put in storage after parameter；
Milling cutter amount of feeding when half finish-milling or finish-milling in the process of above-mentioned [3]~[10] is controlled in 1000~1050mm/
min。
