Hard crisp characteristic, therefore the easily defective work of generation fragmentation when the processing such as being cut or being drilled by CNC toolroom machines, separately
Outside, those skilled in the art also have cuts substitution CNC toolroom machines by common laser, and current radium-shine cutting can generally be divided into ablation
Process (Ablation) and stealthy cutting (Stealth Dicing) two classes.The former is to concentrate radium-shine energy in very short time
It is allowed to evaporate in the tiny area of glass surface, but common laser cutting has and easily causes edge melting and can not be female from glass
The shortcoming that piece is removed；The latter is then concentrated on inside glass with radium-shine, forms modification layer, cutting trace will not be found out in glass surface
Mark.

Embodiment
The above-mentioned purpose and its structure of the present invention and characteristic functionally, the preferred embodiment according to appended accompanying drawing is given
Explanation.
Fig. 1,2,3,4,4a are referred to, is step flow chart, the system of the first embodiment of 3D glass-making processes of the present invention
Schematic diagram and glass viscosity curve map are made, as illustrated, the 3D glass-making processes comprise the following steps：
S1：One 2D glass substrates are provided, and precut (Pre- is carried out to 2D glass substrates with seamless laser cutting mode
) and borehole cut；
The one commercially available glass substrate in 2D states is provided, and borehole is first carried out to the glass substrate by seamless laser cutting
Or the work such as cut, cut size and borehole must consider 3D be molded after size, including glass swelling shrinks and finished product and mould
The steric hindrance phenomenon of tool, it is to avoid because steric hindrance causes finished product not removed after shaping by mould；The seamless cutting
(Perfect Cleave) is a kind of application using ultra-short pulse laser, because Cutting Road (Kerf) width has tapered to zero,
Therefore cutting accuracy is high, machine tool apparatus and the ability of other conventional lasers is exceeded well over, using seamless cutting technique, from glass
Inside is split, but surface is totally smooth, does not have slag splash, is very different with the laser cutting of traditional cognitive, and can
Improve conventional art and produced by CNC processing machines when 2D glass substrates processs and ruptured and the problems such as structural strength is reduced.
The borehole technique, which need to arrange in pairs or groups, is removed clout using general Laser ablation (Ablation), its laser species bag
Include：CW/Plus Type, and it is 1064nm that UV wavelength, which is 355nm or IR wavelength,.
In seamless laser cutting process, wavelength can be focused on a point by the laser beam of glass by object lens,
Then the light beam is scanned along line of cut.Optical system used herein has high focusing performance, can be optical pressure
Be reduced to diffraction limit, thus it is high repeat, that the laser beam of short pulse is temporally and spatially compressed near focal point is very small
Region, with very high peak power density.When can be by the laser beam of glass in compression process, peak value luminous energy be close
When degree exceedes some expansion value, glass starts high-absorbility occur to laser beam, therefore optimization optical system and laser light
The characteristic of beam, can better control over the expansion value of optical density, only exceed the mesh of expansion value in inside glass, near focal point reach
, and the adjustment of expansion value can regard laser beam as Gaussian beam to describe, Laser Focusing is limited to diffraction limit (following diffraction
Limit formula), when expansion of laser light light beam, smaller focus can be obtained, the high energy density of comparison and processing essence is obtained
Degree, but now the depth of focus but shoals (formula of the following depth of focus), therefore become that the processing of shallow-layer can only be done, in processing
, can only be with shorter wavelengths of laser come reached purpose if to do the processing of same precision when comparing thick article, therefore specify
Lasing condition under (beam diameter, transverse mode and beam quality M2 values), by extending depth of focus or multifocal diffraction piece, then with
Lens focus, you can under the focus size of diffraction limit, extends the depth of focus, so just can be with laser beam optionally
Inside glass locality is processed, without destroying glass surface and edge, in the region of laser beam processing, had
Metamorphic layer is formed, and metamorphic layer is as a crack starting point, and crack is vertically elongated, is extended above and below glass front and rear surfaces.It is seamless to swash
Light cutting splits target material from inside, is cut with common laser entirely different from glass outer cutting material.

L：Focal length λ：Wavelength D：Incident light diameter M2：Laser beam quality D.L.Spot size：The focus size depth of focus is public
Formula：
L：Focal length λ：Wavelength D：Incident light diameter D.O.F.：The depth of focus

Heat, the VISCOUS FLOW of glass material (non-newtonian fluid) is a thermo-activation process, wherein, Q is activation energy, and T is temperature, and R is
Mole gas constant and A are approximately a constant.The characteristics of VISCOUS FLOW of non-crystalline material and Arrhenius behaviors have deviation：
(in liquid condition) under high temperature, Q changes from a high value Q at a lower temperature (in glassy state)HTo a higher temperature
Under lower value QL.According to this change, to divide non-crystalline material.
Under conditions of strong:QH-QL<QL or
Under conditions of crisp:QH-QL≥QL.
μ=AeQ/RT
μ=A1·T·[1+A2·eB/RT]·[1+C·eD/RT]
The viscosity of non-crystalline material by a two exponential equation formulas by relatively accurately being described：
Wherein, including constant A1, A2, B, C and D are related to the thermodynamic parameter of the associative key of non-crystalline material.
If temperature is near glass transition temperature, TgThis equation can pass through Vogel-Fulcher-
Tammann (VFT) equation approximate equations (VFT) are represented.
If temperature is less than glass transition temperature, T ＜ ＜ Tg, latter two right exponential equation formula is reduced to one
Arrhenius Equation：
And because QH=Hd+Hm
Wherein, HdIt is the TiFe_xM_y alloy (being referred to as configuron S) and H of scission of linkmIt is that it moves enthalpy.When temperature is less than vitrifying
During transition temperature, T<Tg, the activation energy of its viscosity is high, because non-crystalline material is complete in glassy state and most of associative key.
If temperature is above glass transformation temperature, T ＞ ＞ Tg, the activation energy of its viscosity is low, because non-crystalline material is melt
Change and its most of associative key fracture, this is conducive to flowing.The selection of forming temperature depends on 3D glass finished-product shapes, such as double
