Embodiment
The invention will be further described with reference to the accompanying drawings and examples：
The present invention, to the material of part, shape, size, precision etc., will be processed industrial analysis according to detail drawing.
Processing scheme is reasonably selected, processing sequence, processing route, the mode that is loaded, cutter and cutting parameter etc. is determined；Also to examine simultaneously
Consider the command function of Digit Control Machine Tool used, give full play to the efficiency of lathe；Processing route is short, correctly selects to knife point, changes
Knife point, reduces number of changing knife.With molding cutter time processing portal inner side above and below chamfering, make chamfering consistent.
Fig. 1 to Fig. 5 is referred to, the tool of helicopter lift system fixed disk inner side chamfering processing method of the present invention is given below
Body implementation process：
Step 1：Part and turn-milling complex machining center processing work platform C1 axles are clamped positioning.
Step 2：Roughing endoporus, it is ensured that with one heart
Cutter：Integral alloy drill bit ￠ 10R0mm, total length 160mm hang long 100mm,
The long 50mm of sword, the number of teeth 2；
Cutting parameter：N=1200 F=50
Roughing fork ear two sidetracking is just gone largely in hole, 0.3 millimeter of allowance；
Step 3：Finishing fork ear endoporus, it is ensured that hole precision and position degree
Cutter：Alloy boring cutter boring ￠ 11H7 total lengths 160mm hangs long 100mm,
Cutting parameter：N=1500 F=50
During finishing, surplus is uniform, and bite is identical；
Step 4：Finishing fork earhole inner side chamfering
Cutter：Milling cutter ￠ 10MM total length 160mm of the Integral alloy with sword up and down, as shown in Fig. 2
The high 6mm one sides sword number 4 of the long long 10mm swords of 100mm swords is hanged,
Cutting parameter：Each layer of bite of N=1500 F=40 is not more than 0.3mm
During processing, the milling cutter with sword up and down is passed through into Double-ear-hole, wherein, sword is towards conversely up and down so that sword divides up and down
Not Wei Yu up and down ears inner surface, cutter axially with hole normal direction in the same direction, using it is multi-shaft interlocked progress circular interpolation processing, make
Upper lower fork ear inner side chamfering size is consistent.
In addition, when step 4 is specifically processed, the Shaft angle of turntable rotating shaft C 1 and fork earhole and cutter shaft normal direction are coaxially quickly mobile to pacify
Whole plane, along feed Z-direction with feed motion to upper surface hole depth of chamfering, and is moved to chamfering position progress circular interpolation to Y-direction
Feeding, then returnes to hole center, then feed Z-direction with feed motion to the second Hole chamfering depth, and Y-direction is moved to chamfering position
Progress circular interpolation feeding is put, hole center is returned to, then move quickly into security plane, the Shaft angle 90 of turntable rotating shaft C 1
Degree, carries out next Hole chamfering processing, repeats the above steps, and completes whole Multi-axis simultaneous machining process.
Helicopter lift system fixed disk inner side chamfering processing method of the present invention make above and below on the inside of fork ear chamfer machining it is convenient,
Fast, Dimension Measurement is consistent；It will not in process produce and processed cut problem；Helicopter lift system can be improved
Fixed disk relative positional accuracy, reaches design drawing requirement.
