Description
Technical field
The present invention relates to optical mirror slip processing technique field, the compound motion parameter selection side of more particularly to a kind of main shaft
Method.Further relate to a kind of control device based on the compound motion parameter selection method and compound motion system.
Background technology
In optical mirror slip processing, typically the surface of optical mirror slip is added by machining center main shaft drives bistrique
Work, removal distribution and processing speed common mathematical function model quantitative description, the mathematical modeling of the bistrique to lens materials are claimed
To remove function.The theoretical model for removing function is generally basede on Preston linear hypothesis.The surface error of optical mirror slip to be processed
Distribution is referred to as face shape error.Optical mirror slip processing process it is actual be exactly using remove function pair face shape error progress convolution
Process, residence time, i.e. residence time of the bistrique in every processing of workpiece surface can be obtained by the solution of deconvolution.With
The development of computer technology, said process can be controlled by computer and realized, the technology is referred to as CCOS, and (English full name is
Computer controller optical surfacing) technology, contemporary optics processing generally use CCOS technologies.Bistrique
Forms of motion it is different, the removal function that it is obtained is also different.A kind of currently used removal function is the removal letter of Gaussian
Number, it has preferable face shape convergence effect in optical manufacturing.Function is removed in order to obtain Gaussian, main shaft drives bistrique enters
The flat rotational motion of row realizes the type and removes function, i.e., to turn axle, the both ends for turning axle connect main shaft with drive device and bistrique respectively
Connect, radial deflection be present between the pivot center of main shaft and the central axis of bistrique, so as to realize bistrique by main shaft rotation
Flat turn is moved.
Existing Gaussian removes function when solving the convergence problem of workpiece to be processed edge, faces edge effect：One
Aspect, when grinding head center gets too close to the edge of work (stretching rate is high), edge pressure can be caused to concentrate, cause to remove function
Distribution changes and influences to remove precision, or even causes bistrique to topple；, whereas if bistrique stretching rate is low, function peak is removed
Value causes the material removal amount of the edge of work substantially relatively low on the inside of workpiece, produces alice.Such as when bistrique moves to optics
During lens edge, lens edge can not but be reached by removing the peak value of function, now central distance of grinding lens edge 100mm, therefore
Computing or control residence time anyway, it is contemplated that the flat turn of lens edge bistrique is dynamic to have bias, then total in the range of 90mm
Edge can not be reached and caused alice due to removing peak value by occurring, this is the reason for edge effect produces " alice "；And
When mill stretches out the increase of lens edge size so that peak value remove to lens edge move when, although the peak width of alice
Meeting constriction, but alice problem is still present, and as mill stretches out the increase of lens edge size, gone caused by stress change
Except the risk that function mutation can cause removal amount locally to be uprushed increases, urgency " turned-down edge " problem is just generated.It is thus impossible in order to disappear
Increase the size that bistrique stretches out lens edge too much except alice.This edge for having resulted in optical mirror slip can not be rolled up completely
Product.
In order to solve the problems, such as Gaussian remove function edge can not complete convolution, a kind of H-Z recently disclosed
Sharp knife removes function, and the removal function is realized by two kinds of motion synthesis, i.e., is moved by the flat turn of bistrique and spinning motion closes
Into realization, on the basis of keeping flat turn to move the advantages that Gaussian removes function excellent volume clearance, make removal function
Peak value clearance is to the movement of function edge is removed, and so, need not excessively stretch out optical mirror slip edge even if bistrique can also make removal
Rate peak value reaches the outward flange of optical mirror slip, so as to solve the problems, such as alice while turned-down edge is avoided, is realized from algorithm
The complete convolution convergence of class of optical mirror slip edge, realizes the suppression of edge effect, improves bistrique in the edge of work

Wherein, alice remnants rates TUR is by edge residue alice amount A3With the actual edge removal amount A for removing function1Obtain,
Removal effect can be quantified, alice remnants rates TUR is smaller, then shows, alice is smaller, and the suppression to alice is more effective.Such as Fig. 2 institutes
Showing, bistrique runs well, and removes function at the uniform velocity inswept straight line on workpiece, can produce a uniform trench and remove band,
What the curve in Fig. 2 represented is the cross-sectional profiles line of the hook-shaped removal band at the edge of work, it can be seen that because bistrique stretches out
An edge part for workpiece, therefore, in fig. 2, the hook-shaped cross-sectional profiles line part for removing band is located at outside edge, institute
With A in Fig. 21Represent be remove function actual edge removal amount, A2What is represented is to remove function to stretch out overflowing for edge
Except amount (not acting on workpiece), A1And A2And represent remove function theory whole removal amounts, A3What is represented is edge residue

Centre, more symmetrically, A3Partial area is larger；The peak value of the curve on right side is close to edge, A3Partial area is smaller, that is, sticks up
Side is smaller.
Sharp knife coefficient k is equal to the maximum rotation angle of bistrique and 2 π ratio, and the rotation of bistrique is reciprocal according to some cycles
Rotation, preferably according to sinusoidal cycles rotation, sharp knife coefficient k is bigger, represents that the maximum angle of rotation is bigger, identical from turn-week
Under phase, the speed of rotation is faster.
Bistrique eccentricity ratio e is equal to radius of turn and the ratio of bistrique diameter that bistrique flat turn is moved, and bistrique eccentricity ratio e is bigger,
Represent that the workpiece scope of the dynamic removal of flat turn of bistrique is bigger, under identical flat rotation period, the linear velocity of bistrique is bigger.
Bistrique stretching rate S is equal to the ratio of maximum polishing diameter of the bistrique maximum extension elongation with removing function, due to mill
Head center to the edge of work it is close when, understand some and stretch out edge of work, by the eccentric flat turn of bistrique is dynamic calculate including, bistrique energy
The maximum length for enough stretching out the edge of work is exactly bistrique maximum extension elongation, and the maximum polishing diameter for removing function refers to removing
The maximum gauge of the theory movement scope of function.Bistrique stretching rate S is bigger, represents that the edge length of bistrique stretching workpiece is bigger,
Grinding head center is closer to the edge of work.
The alice remnants rates TUR that the above method is drawn out in analog simulation is with can be with bistrique stretching rate S change curves
Sharp knife coefficient k, bistrique eccentricity ratio e and the bistrique that OK range is chosen according to the alice remnants rates TUR of setting desired value stretch out
Rate S.As long as meeting the alice remnants rates TUR of setting desired value, then removing function just can effectively suppress the edge effect of workpiece
Should.
As shown in Fig. 2 in the present embodiment, alice remnants rates TUR is by edge residue alice amount A3With the reality for removing function
Border edge removal amount A1Obtain, be specially：
As shown in figure 1, in the present embodiment, depending on processing operating mode, different adds alice remnants rates TUR desired value
Work operating mode, it needs the alice surplus difference met.Preferably, process operating mode include workpiece size, workpiece face shape error and
Technology type.The often bad removal of the alice of large-size workpiece, therefore, the alice remnants rates TUR of large-size workpiece desired value
It can be set to somewhat higher.
In the present embodiment, when defining alice remnants rates TUR desired value≤15% to 20%, edge effect can obtain
Preferably suppress, certainly, according to different processing operating modes, alice remnants rates TUR desired value can suitably change, more preferably
Alice remnants rates TUR desired value≤15%.
As shown in Figure 3 and Figure 4, the alice remnants rates TUR for removing function to different H-Z sharp knives for convenience stretches with bistrique
Extracting rate S change curves are analyzed, in the present embodiment, to multiple with different bistrique eccentricity ratio e and sharp knife coefficient k
H-Z sharp knives remove function and carry out analog simulation respectively, draw out each H-Z sharp knives and remove the alice remnants rates TUR of function with mill
Head stretching rate S change curves method be specially：
Multiple H-Z sharp knives with same bistrique eccentricity ratio e and different sharp knife coefficient ks are removed to the alice remnants rates of function
TUR is plotted in a H-Z sharp knife with bistrique stretching rate S change curves and removes the alice remnants rates TUR of function with bistrique stretching rate S
In change curve.I.e. in an alice remnants rates TUR with bistrique stretching rate S change curves, the mill of multiple change curves
Head eccentricity ratio e is identical, respectively with different sharp knife coefficient ks.From Fig. 3 and Fig. 4 as can be seen that in same bistrique eccentricity ratio e
Under, sharp knife coefficient k is bigger, is more advantageous to reduce alice remnants rate TUR, bistrique stretching rate S is bigger, is more advantageous to alice remnants rates
TUR reduction, contrasted by Fig. 3 and Fig. 4, it is known that, bistrique eccentricity ratio e is smaller, is more advantageous to alice remnants rates TUR reduction.
Specifically, when the desired value for thinking alice remnants rates TUR is less than 15%, edge effect has obtained preferable suppression
System, is set forth below the alice remnants rates TUR under two different bistrique eccentricity ratio e with bistrique stretching rate S change curves.First
Kind, in the case where bistrique eccentricity ratio e is 1/10, the simulation result of material removal amount as shown in Figure 3 is obtained, in figure 3, is being ground
When head stretching rate S is 0.1, sharp knife coefficient k=0.2 can meet the target that alice remnants TUR are less than 15%.Second, grinding
In the case that head eccentricity ratio e is 1/5, simulation result as shown in Figure 4 is obtained, when bistrique stretching rate S is 0.05, sharp knife system
Number k=0.1 can meet the target that alice remnants TUR are less than 15%.If take other parameters and alice remnants rates TUR target
Value, it can realize that alice remnants rates TUR convergence presses down by bistrique stretching rate S, sharp knife coefficient k, bistrique eccentricity ratio e parameter combinations
System.
From figs. 3 and 4 it can be seen that as sharp knife coefficient k constant amplitude is lifted, to alice remnants rates TUR inhibitory action by
It is decrescence weak, when sharp knife coefficient k increases to some value k0When, it is further continued for increasing sharp knife coefficient k, the suppression to alice remnants rates TUR
Effect almost no longer changes, and reaches the limit of.The sharp knife coefficient k0Meet formula：That is sharp knife coefficient
K span isDue to sharp knife coefficient k for bistrique rotation maximum angle and 2 π ratio, because
This, as long as the maximum angle of bistrique rotation meets k0During corresponding extreme angles, just most beneficial for alice remnants rates TUR suppression
System.And the maximum angle of bistrique rotation is realized by corresponding equipment to drive, bistrique is disclosure satisfy that in the drive condition of equipment
When the maximum angle of rotation reaches the limit values, then select equipment to should limiting value drive condition, so as to residual according to alice
When remaining rate TUR chooses running parameter with bistrique stretching rate S change curves, only choose bistrique eccentricity ratio e's and bistrique stretching rate S
Span.The equipment of the maximum angle limiting value of bistrique rotation can not be reached for drive condition, then in the driving energy of equipment
Under power, when choosing running parameter with bistrique stretching rate S change curves according to alice remnants rates TUR, sharp knife coefficient k, mill are chosen
Head eccentricity ratio e and bistrique stretching rate S span.
It is not difficult to find out from Fig. 3 and Fig. 4, small abrasive nose eccentricity ratio e, big bistrique stretching rate S, big sharp knife coefficient k, is advantageous to reduce
Alice remnants rate TUR, obtain more preferable processing effect.But also have a negative impact simultaneously to other aspects, it is as shown in table 1 below,
Therefore need to consider and choose bistrique eccentricity ratio e, bistrique stretching rate S and sharp knife coefficient k.
The bistrique eccentricity ratio of table 1, the influence of bistrique stretching rate and sharp knife coefficient to other running parameters
Certainly, in addition to taking the Drawing of Curve mode in Fig. 3 and Fig. 4, each H-Z sharp knives can also be removed function list
Solely be plotted in different change curves, can equally be chosen according to alice remnants rates TUR desired value bistrique eccentricity ratio e,
Bistrique stretching rate S and sharp knife coefficient k scope.
