Detailed description of the invention
In order to make objects and advantages of the present invention clearer, below in conjunction with embodiment to this
Bright it is specifically described.Should be appreciated that following word is only in order to describe the one of the present invention or several
Planting specific embodiment, the protection domain of not concrete to present invention request carries out considered critical.
The processing method of a kind of aerial blade, specifically includes following operating procedure:
Roughing: roughing uses the processing mode of helical milling that the blank of round flat shape is approximated processing
To blade shape, after roughing, leave surplus 1mm, in order to improve rough machined working (machining) efficiency, choosing
SelectEndless knife, construct helix according to drive surface and shadow casting technique, further according to operation S1
The method of structure helical milling forward and back cutter, constructs multi-layer helical line tracking according to operation S2, uses
Cutter be carbide tool, so the amount of feeding of every layer is arranged to 2mm, so can improve
Rough machined efficiency.
Semifinishing: semifinishing is to prepare for polish below, so semifinishing is stayed remaining
Amount is that the experiment according to polish determines, leaves according to the contrast test semifinishing of polish
Surplus is 0.1mm and 0.2mm, and semifinishing usesBall head knife, cutter material is high
Speed steel, according to drive surface in operation S3 and shadow casting technique's structure helix, further according to operation S1 structure
The method making the forward and back cutter of helical milling, determines the numerical value of cutting width finally according to operation S4；
Polish: polish is a most important link in blade digital control processing, and blade blade
Processing be again most important part in blade polish, and blade to processing after surface matter
Amount, the whole profile tolerance of cross sectional shape and blade have higher requirement, thus to use one complete
Whole cutter path completes the processing of whole blade portion, and the deflection of blade will be required
Within the scope of；
The track of polish be according to operation S3 with initial control line and terminate control line for boundary with
The method of interpolation directly constructs helix, and projects along spoon of blade normal direction, it is ensured that helix is tight
Lattice are limited on curved surface.Then the method constructing the forward and back cutter of helical milling further according to operation S1,
The axial motion mode of straight line, the spiral trajectory of structure such as Fig. 1 institute is used at forward and back cutter section start
Show.
Wherein:
Operation S1: helical milling forward and back cutter trajectory creation method
When cutter incision workpiece, need to control many parameters of lathe, such as: the cutting of cutter
Consumption, the speed of mainshaft and the direction of motion, be so in order to cutter, lathe and workpiece do not interfere,
In NC programming, cutter incision this section of track of workpiece is referred to as feed track, and accordingly, cutter cuts out workpiece
Track be referred to as withdrawing track.
The feature of feed track is to cut the most uniformly along Cutting trajectory tangential direction, cut out work
Part；Common feed mode has that rectilinear tangential, circular arc be tangential, vertical, oblique line, shape, spiral
Formula feeds etc., withdrawing mode has rectilinear tangential withdrawing, straight line withdrawing etc..
Vertical feed: this tool feeding method is the most vertically to be cut workpiece by cutter, can produce the biggest
Impulsive force, and the deflection of cutter and workpiece is strengthened, this method is generally used for keyway milling
Cutter；
Oblique line feed: this feed mode is to use side edge cutting workpiece, adds man-hour requirement and sets cutter
Angle between tool axis and workpiece；If angle setting is the least, then each cutter incision is deep
Spend shallower, be conducive to protection cutter and workpiece, but working (machining) efficiency can be the lowest；If chosen
Angle excessive, will produce end sword cutting situation；So this angle to be processed according to reality
Need to arrange；
Shape feed: this feed mode is the improvement of oblique line feed, whole oblique line feed divide
For the oblique line feed that many steps are little, although the problem also having cutter both sides blade discontinuity,
But each walking journey is the least, so deformation is the least；
Spiral feed: this feed mode is from inside to outside to process, namely from the beginning of topmost,
Downward spiral is processed, and it have employed the mode of Continuous maching, is easier to ensure machining accuracy, and
And the less depth of cut, cutter can be utilized to decline slowly, it is to avoid and the generation of inclined sword cutting, carry
High cutting wear；For blade screw milling method, how to enter to select cutter mode, be
Affect one of importance of blade processing quality.If it is considered that if blade processing efficiency, then want
Control blade and enclose the speed being rotated about axis.If this speed can reach maximum as far as possible,
So production efficiency of blade processing will improve a lot.Concrete control method is exactly: when
Leaf is when cutter incision workpiece, and this rotary shaft velocity of rotation is rapidly increased to maximum by zero.Thus
Cause blade screw Milling Machining must have a feed mode of oneself uniqueness, hereinbefore mention various
Feed mode is only appropriate to common process, is not suitable for helical milling processing.And helical milling is the most reasonably cut
Enter mode to control cutter exactly and slowly cut part along blade profile profile, make cutter path at blade
Envelope spiral-shaped based on around forming blade profile wire shaped, the most not only can improve
The machining accuracy of blade, moreover it is possible to improve the working (machining) efficiency of blade, as in figure 2 it is shown, just cut out mode
Good in opposite direction when cutting with cutter.
Operation S2: multi-layer helical line tracking building method
Path is divided into starting stage, cutting stage and termination phase, feed according to feed process
Occurring in starting stage and cutting stage, withdrawing occurs at cutting stage and termination phase, in cutting
The forward and back cutter in stage is referred to as interlayer advance and retreat cutter, for connecting different Cutting trajectory sections.
Blade processing may use in situations below and arrive multi-layer helical line tracking:
A, blank allowance are relatively big, and roughing needs to be divided into multi-layer helical line and is processed；
B, roughing and semifinishing cutting output are different, are merged into one when using with during cutter
Secondary operation；
The construction process of multi-layer helical line Cutting trajectory is divided into structure interlayer feed track, constructs this layer
Cutting trajectory, structure three steps of interlayer withdrawing track:
Structure interlayer feed track: set helical milling feed track and be divided into the n-layer, every layer of thickness of cutting to be
Hi, i=0,1 ... n, cutter is slowly cut part along blade profile profile, is formed to cut in blade
Upper thread is shaped as the helix shape on basis, and the setting of thickness of cutting array hi can be easy to reality
The now thickness even variation of every layer of feed track.
Structure current layer spiral cutting track: if current layer cutting depth is uniform equal thickness, only
Spoon of blade need to be biased for cutting depth according to distance, biasing surface constructs screw processing
Track.If during current layer cutting depth uneven gauge, then need to formulate non-uniform offsetting and calculate
Method constructing curve, then constructs current layer screw processing track on biasing surface.
Structure interlayer withdrawing track: for multi-layer helical line processing method, selects withdrawing track to have two
The mode of kind, the first is considered working (machining) efficiency, is not carried out withdrawing, but directly carry out next layer and enter
Cutter (Fig. 3-1), omits withdrawing step, then the direction of feed of adjacent two layers helical trajectory is contrary.Separately
One does not omit withdrawing step, adds and moves cutter instruction, can arbitrarily select access site (Fig. 3-2).
Construct multi-layer helical line tracking time, the thickness of every layer can be definite value can also be variate, root
The cutting situation on border determines the thickness of cutting of every layer factually.
Operation S3: the structure of blade screw line
Helix is directly constructed with the method for interpolation: construct the base of helix shape in parameter field
This method is to construct helix at parameter field, and principle selects proper sequence in Surface Parameters territory
Parameter point, constructs helix in the way of interpolation.In parameter field, the method with interpolation directly constructs
Helix, concrete principle is as follows: sets blade curved surface spline surface and is expressed as S, along blade profile
The direction of line is defined as u parametric direction, and the direction along blade radial line is defined as parameter field direction v
Parameter.Span in S is all typically canonicalized as [0,1].If blade curved surface S and tenon
End face and blade tip end and intersection be respectively C0And C1, then the border, effective coverage of blade curved surface by
C0And C1Article two, intersection determines, in order to make helix from C after m encloses0It is transitioned into C1, can be
The u parameter line race T:{T such as the upper structure of Si, i=1 ... n}, to C0And C1Article two, intersection carries out weight
The most discrete.If T and C obtained after discrete0Intersection point collection be combined into P:{Pi, i=1 ... n}, T with
C1Intersection point collection be combined into Q:{Qi, i=1 ... n}.If T being carried out m etc. with P and Q for border
The mesh node collection obtained after Fen is combined into L:{Lij, i=1 ... n, j=1 ... m, wherein L0i=Pi,
Lmi=Qi, then it is positioned at the i-th row, the grid interpolation value point A of jth row on helixij(u, v) can profit
Calculate with following two formula:
A dextrorotary helix and one is can get to the spiral shell of anticlockwise according to formula above
Spin line, according to the order of v after first u, makes two parameters be incremented to 1 from 0 respectively, calculates institute
Some interpolation point Aij(u, v).Then, be linked in sequence all of point, can give birth in parameter field
Become a continuous print broken line, this broken line correspond in the model space blade bent and at C0And C1Territory
The helix of internal Rotating with Uniform.In parameter field, the method advantage of structure helix is to calculate speed
Hurry up, algorithm is simple, and shortcoming is that this algorithm is only used for individual closed surface, the shape of helix
The most single, be not suitable for constructing the complicated shape helix with good process.
Helix is constructed: in numerical control programming, have a kind of programming side based on drive surface and shadow casting technique
Method is to utilize drive surface and shadow casting technique's structure machining locus shape, the process of this programmed method
It is: first from driving solid tectonic forcing point, then driving o'clock is along a projected vector specified
Direction projects part geometry body, forms incident point.Incident point is appointed as cutting in cutter location computing
Contact track or cutter location track.The advantage of this programmed method is very flexible, and driving solid can
To be appointed as overlapping with processing curve, it is also possible to be the solid unrelated with processing curve, projection side
The selection of method is the most varied, both may be selected to be the vector side that fixed vector direction or cutter shaft are relevant
To, it is also possible to it is the vector relevant to drive surface.This programmed method flexibly be applicable to three axles,
Multiaxis programming technique, is the important method of numerical control programming.The more flexible property of the method, effectively controls
Helix shape.It is critical only that of sciagraphy structure helix selects to drive solid and projection side
Formula, the present invention is using cylinder as driving solid, and structure is suitable for Four-axis milling according to the following steps
Blade screw line point of contact track:
A, structure cylinder are as drive surface.Cylinder should completely include blade, cylindrical
Radius can be any；
B, construct circular helix on the cylinder.The equation of circular helix, optional parameters is
Pitch, direction of rotation, original position etc.；
C, projection.Reference point on circular helix is starting point, crosses reference point and makees cylinder axis
Vertical, vertical is projection terminal with the intersection point of cylinder axis, and the intersection point of projection and blade is for throwing
Shadow point；
D, structure blade screw line, the subpoint that is linked in sequence can construct blade screw line, adjacent
Between subpoint, region can use interpolation or parameter field interpolated value.
Plane seeks friendship segmented construction blade screw line: in numerical control programming, sometimes for ensureing blade office
Portion's shape, may require that the helix shape in this region meets particular/special requirement.The shape of edge head is
One of blade processing requirement, for the ease of manual relief grinding edge head, it is desirable to after digital control processing at edge head
Scallop-height uniformly and ensure that there is edge head shapes, this requires the track of edge head and edge head section line
Similar, use common programmed method to be difficult to meet this requirement.Employing plane is presented herein below and seeks friendship technology
Structure edge head helix, meets the segmented construction blade screw line side of edge head leftover traces shape need
Method:
A, structure auxiliary plane group.Auxiliary plane group selection is perpendicular to two groups of planes of axis of runner blade,
Spacing between family of planes midplane is all pitch h, and one group of plane is separated by h/2 with another group plane
Spacing.
B, set of planes and spoon of blade seek intersection.This two races plane and blade ask friendship can obtain two
Race has the curve group of edge head shapes.
C, cut out edge head shapes family of curves with restriction face.Definition needs to keep the blade of edge head shapes
Region, generally uses plane or curved surface to go to limit, goes to cut out the curve that upper step obtains with this restriction face
Group, obtains the curve of blade profile edge head shapes.
D, two ora terminalis head rail trace curve overlap joints.Curve after restriction face is cut out is divided into before and after two groups,
Overlapping in order between two suite lines, bridging method has blade parameter territory interpolated value or Ai Er meter
Special interpolation method.
E, overlap joint curve projection.Overlap joint curve if not using parameter field interpolated value method, then has
May not fall on spoon of blade, therefore be projected to spoon of blade by overlap joint curve, projecting direction is optional
Mode is needed for overlapping one of curve two hold-carrying arrow or other.
F, it is linked in sequence edge cephalic flexure line and drop shadow curve i.e. constitutes blade screw line.Three of the above structure
The method making blade screw line cuts both ways.Parameter field interpolated value method is simple, be easily achieved, but
Being to be only applicable to single closed surface, at edge head, curve shape is with edge head section line form variations relatively
Greatly；Drive surface-projecting method is flexible, easy-to-use, curve shape and edge head section line shape at edge head
Deviation is also little, but at blade back, leaf basin, form variations is bigger；Plane asks friendship segmented construction method to use
Arrive curved surface and plane has asked friendship, curve to cut out, curve compares to curved surface projection scheduling algorithm, amount of calculation
Greatly, but helix shape can control completely.Parameter field interpolation value method, drive surface-sciagraphy
All can not well adapt to the feature that blade profile Curvature varying is big, only segmented construction blade screw
Line could solve this problem.
