Expense, the consumption of auxiliary gas in reduction laser cutting process, and the actual amount of movement of Digit Control Machine Tool is reduced, while reducing
Screw mandrel way rub, improves the life-span of equipment, has filled up domestic blank.
Description of the drawings
Fig. 1 is Optimizing Flow figure of the present invention.
Pathway figures of the Fig. 2 for ordinary two dimensional Nesting.
Fig. 3 is the pathway figure of two dimension layout method of the present invention.
Fig. 4, Fig. 5 are the pathway figure of three-dimensional Nesting of the invention.
Specific embodiment
Below according to accompanying drawing, the present invention is described further.
As shown in figure 1, concrete grammar is as follows：
（1）Read IGES graphic files；
（2）IGES figures are calculated along girth, the front end face data of IGES figure Y-directions are obtained；
（3）Judge whether IGES figures Y-direction has slot structure, be, IGES figures are carried out into array sequence；Otherwise directly initiate
Follow-up diced system；
（4）IGES figures carry out array sequence, and starting starts to sort successively with 0；
（5）The IGES figures of odd indexed are carried out 180 ° along Y-direction to turn round；
（6）The odd indexed figure of IGES figures carries out, after 180 ° of renewals of turning round, obtaining new IGES graphic arrays row along Y-direction
Sequence；
（7）Carry out follow-up diced system.
Y-direction is Y-axis positive direction.
Slot structure be square slot structure, curved slot arrangement, vee gutter structure, in polygon geometric form slot structure one
Kind.
As shown in Fig. 2 the pathway figure of ordinary two dimensional Nesting, its result is：L1=2a+4b+4c+2d, and clout chi
It is very little for b × c.
As shown in figure 3, the pathway figure of two dimension layout method of the present invention, its result is：L2=a+4b+2c+d, and clout chi
It is very little for 2b × c.
Path mathematic interpolation：ΔL=L1-L2=a+2c+d=（a+c+d）+ c=Width+c, wherein, Δ L is path difference；
Width is the intrinsic width dimensions of part.
Thus fiducial value, draws (the machine tool amount of movement short for the cutting path of the Nesting of sheet material of the present invention
Little, laser energy input is low), clout size is big (high recycling rate), and the key of Nesting Algorithms proposed by the present invention is by groove class
Part can not produce it is common while cutting mode arrangement be local it is common while cut.
It is assumed that certain plate material parts size is 100mm × 100mm, and groove 50 × 50mm of size, common cutting path overall length is
500mm, and method cutting path overall length in altogether side proposed by the present invention is 350mm, a pair of parts save 150mm（About 30%）.
In the same manner, the cutting problem algorithm on such local common side can be generalized in the jacking Nesting Algorithms of tubular object extruding,
Following Fig. 4, shown in Fig. 5, traditional cutting method is exactly to be cut according to the figure shown in Fig. 4, after completing one, carries out the
The cutting in two same paths.And using the present invention, directly cutting pattern can be ranked up according to the array shown in Fig. 5,
Then cut.
The method for optimizing route of the present invention can be placed on the preamble of common cutting software flow process, have no effect on subsequently cut it is soft
Part, simply just cuts the calculating and optimization in advance walking along the street footpath, saves cutting cost to a greater extent.
Sheet material and tubing of the present invention for irregular trough of belt class, all with practical value, traditional is commonly total to side method
Only consider the method that the public end face of the direct plane formula of part can be imposed uniformity without examining individual cases, complicated shape can not done all altogether
Under the mode on side, the algorithm that can be optimized to locally be total to side by upper computer software carries out stock layout, path optimization proposed by the present invention
Method is to be extremely improved, and proposes new demand to upper computer software algorithm function, it is desirable to the algorithm of upper layer software (applications) CAD/CAM
Process and optimization, identify the feature of groove class part.
The economic worth of the present invention is huge, and for numerical control device with high costs, the notable shortening of machining path is carried
High working (machining) efficiency, reduces time overhead, directly affects amount of movement and the power consumption of servomotor, directly reduce laser instrument
The consumption of energy consumption and protective gas, synchronously increased the service life of the drive disk assembly of equipment（Reduce screw mandrel or tooth bar or
The abrasion of decelerator guide rail）.Especially in the workshop of processing huge number, while efficiency increases, the energy consumption of saving is especially pronounced.
By 3D solid along stock layout direction（Acquiescence Y-direction is the axis direction of tubing）, Shanghai is taken charge of by me in this case
The independently developed CypTubeLaserCuttingSystem tubing laser cutting system software reality of Bai Chu Electronic Science and Technology Co., Ltd.s
It is existing.
