Abstract
The invention provides an operating method for fully and automatically processing M8*1 inner threads through a numerical milling machine tool. The operating method is characterized by comprising the following steps: (1) starting a CATIA (computer-graphics aided three-dimensional interactive application) program and selecting orders in the program; (2) setting a tool cutting path, wherein the processing mode is spiral processing, the processing direction is set to be from the beginning to the end, the processing tolerance is set to be 0.01 mm, the processing distance is set to be 0.1 mm and the cutting layer number is set to be 5; (3) setting thread cutting amount and outline offset amount according to thread specifications; (4) selecting a universal thread milling cutter, wherein the cutting speed of the tool is set to be 120 mm-180 mm, the rotation speed of the tool main shaft is set to be 890-1000 n/min; (5) processing internal threads.
Description
Technical field
The present invention relates to the processing method of machine components, particularly to the side using milling mode overall processing female thread
Method.
Background technology
Discrimination pipe part is a kind of porous part, and for the connection of aircraft multi-pipeline, therefore its piece surface comprises crowd
Many screwed holes.Common turner machine add mode needs a hole assembly will once organize co-clip when processing such part screwed hole
Tool, is unfavorable for the efficient processing of part, easily quality problems simultaneously.Domestic useful several milling modes process screw thread (only plus
Work screw thread) but its to be machine-tool operator utilize number milling machine tool from threaded program the manual programming through row, this mode cannot expire
The processing of sufficient manifold, and workman is required too high it is impossible to meet reality processing demand.
Content of the invention
The invention provides a kind of operational approach of several milling machine tool full-automatic processing m8 × 1 female thread, comprise the following steps:
(1) startup catia program, select command in a program,
(2) tool cutting path is set, and processing mode is set to spirally process, and machine direction is set to from first to last,
Machining tolerance is set to 0.01mm, and processing spacing is set to 0.1mm, and the cutting number of plies is set to 5；
(3) cutting output and contour offset amount are threaded according to screw thread specification；
(4) universal threaded milling cutter, the cutting rate setting 120mm-180mm/min of cutter are selected, speed of cutter spindle sets
It is set to 890-1000n/min；
(5) carry out the processing of female thread.
One embodiment of the present invention being threaded in cutting output and the step of contour offset amount according to screw thread specification,
Milling thread diameter is set to 8.12mm to 8.14mm, and contour offset amount is set to -0.068mm to -0.072mm.
Design size can be fully met through the female thread that the actual verification present invention is processed to require, and Part Surface Roughness
More traditional machine add mode is greatly improved.Achieve one-time positioning clamping so that it may process multiple screw threads in same plane
Target, improves production efficiency simultaneously, reduces part rejection rate.
Brief description
Fig. 1 is internal thread machining schematic flow sheet
Specific embodiment
1st, internal thread machining:
Select command (thread milling) in catia program during machining internal thread, and enter line parameter by blanking step
Setting:
(1) tool cutting path is set:
1st, arrange in strategy option:
Processing mode: maching strategy is chosen as: optimized pass (spiral processing).
Machine direction: maching directiong selects: top to bottom (from first to last).
Machining tolerance: machining tolerance: be set to: 0.01mm.According at present count milling machine tools precision, such as
Fruit is set lower than 0.01mm, makes after internal thread machining, and routine data amount is excessive, easily causes lathe computer crash.If setting is high
In 0.01mm, female thread is also easy to produce burr.
2nd, arrange in stepover option:
Processing spacing: distance between paths:0.1mm.
The cutting number of plies: number of paths:5.Amount of separation is higher than 0.1mm or is also easy to produce, less than 5 layers, knife phenomenon of quivering,
Away from amount higher than 0.1mm or time-consuming too high higher than 5 layers.
(2) screw chasing amount setting: the pitch in screw thread is ensured by screw cutter
Milling thread diameter: 8.14mm (m8 × 1 parameter)
Contour offset amount: offset on contour:-0.07mm (m8 × 1 parameter)
If less than 8.12 or contour offset amount is higher than -0.068mm to the setting of milling thread diameter, the thread size cutting
Will be lower than minimal tolerance；The setting of milling thread diameter is less than -0.072mm, Jiu Huigao if above 8.14 or contour offset amount
In maximum allowance.Both of which occurs that screw thread is unqualified.
(3) cutting tool choice: the cutter of use is universal threaded milling cutter.
(4) tool sharpening parameter:
1st, arrange in feedrate (processing feed rate) option:
Approach (rate of feed of cutter): 200mm.
Plunge (the cutter lifting speed of cutter): 10mm.
Maching (cutting rate of cutter): 150mm.The cutting rate setting 120mm-180mm of cutter, female thread light
Cleanliness is higher, and cutting rate is very fast.It is 150mm in the cutting rate of cutter, female thread fineness highest, and cutting rate is relatively
Hurry up.
Retract (the withdrawing speed of cutter): 1000mm.
Spindle speed (rotating shaft speed) option is arranged:
Maching (speed of cutter spindle): 950turn.
(5) carry out internal thread machining.
Claims (2)
1. the operational approach of number milling machine tool full-automatic processing m8 × 1 female thread is it is characterised in that comprise the following steps:
