Description
Technical field
It is the invention belongs to two-dimensional blanking sample layout optimizing field more particularly to interactive based on group two-dimensional rectangle part of change technology
Sample layout optimizing method.
Background technology
Interactive stock layout is combined in so-called group of change (Grouping), the section that will have same or similar attribute.
After forming layout project, on the basis of stock layout constraint is not destroyed, support manually adjusts layout project.
The problems such as traditional Nesting does not consider subsequent technique, workshop transport, Job-Shop, the section of same specification is being cut
Cut and be distributed in scheme scattered, line of cut is in disorder；Layout project after generation can not be manually adjusted, and layout project man-machine interaction is poor.
The content of the invention
The purpose of the embodiment of the present invention is to provide a kind of two-dimensional rectangle part interactive mode sample layout optimizing based on group change technology
Method, it is intended to solve existing technology do not consider subsequent technique, workshop transport, Job-Shop the problems such as, the section of same specification exists
It is distributed scattered in cutting scheme, line of cut is in disorder；Layout project after generation can not be manually adjusted, and layout project man-machine interaction is poor
Problem.
The embodiment of the present invention is achieved in that a kind of two-dimensional rectangle part interactive mode sample layout optimizing side based on group change technology
The step of method, the method, includes：
Step one, groupization process：Data are completed first to prepare；
Step 2, groupization process：Carry out section rectangular-shaped piece in groups；
Step 3, groupization process：Cropping and blank layout is carried out using the principle of " most left most to descend optimization "；
Step 4, the interactive stock layout based on section combination：Support operating personnel easily real by mouse-keyboard
Now cut into slices addition, deletion, rotation, locomotive function on former piece, and easily stock layout layout can be amplified, reduced；
Step 5, the interactive stock layout based on section combination：When being adjusted to stock layout layout, system provides real-time
Collision detection, it is automatic to ensure not overlapped between section, cut into slices without departing from the edge of former piece；
Step 6, the interactive stock layout based on section combination：It is optimization mesh with line of cut total path after the completion of interaction stock layout
Mark generation line of cut and cutting sequence.
Further, this method meet clean cut technique, i.e. raw material rectangular-shaped piece formed after a sawing sheet two section squares
Shape part；Same batch, the section of same specification are discharged together as much as possible, are transported in order to subsequent technique and workshop shelf.
Further, the mode of extreme saturation and breadth traversal is respectively adopted in step 2 and step 3, will be with identical
The section of width or length forms a series of combinations by the principle of " same edge connects ", wherein the width for combining is with the width of raw material
It is limitation to spend, and section therein allows rotation.
Further, the coordinate for the rectangle r1 lower left corners being assumed in step 5 is (x1, y1), and width is w1, and height is h1；Rectangle
The coordinate in 2 lower left corners is (x2, y2), and width is w2, and height is h2.Compare 2 coordinates of rectangular centre point in the x and y direction
Distance and 2 rectangle width height relations, you can to judge whether 2 rectangles have overlap.If 2 rectangles have overlap,

In nesting, it is only necessary to which condition above is converted into code can just realize the collision inspection of rectangle section
Survey.When rectangle section is added, is rotated, moving operation when, current rectangle section is in former piece coordinate system after the completion of operation
Position data can change, the current slice in new position and other sections are carried out into collision detection, if do not occurred again
The folded edge not departing from former piece, then operate the data for successfully updating Layout；If current slice is cut with other after operation
Piece overlaps or beyond the edge of former piece, then this operation will be cancelled.
Further, the generation scheme of line of cut is as follows in step 6：
(1) in all horizontal, longitudinally cutting lines, from that article of closest line of cut of Layout lower-left angle point as
One line of cut, if the line of cut direction is horizontal, cuts all again after all transverse cuts for having cut the Layout
Longitudinally cutting line；If the line of cut direction is longitudinal direction, cut again after all longitudinally cutting line for having cut the Layout all
Transverse cut, we are using line of cut A → B as first line of cut.
(2) in cutting laterally (longitudinal direction) line of cut, make similar " S " broken line of travel track of cutter, be in same straight
The cut direction of the line of cut on line should be identical, records axial number where first line of cut after each cut direction changes
It is λ to be worth；Do not change the small line of cut of axial numerical value where preferential cutting during cut direction, and opened from the end points close to cutter
Begin, cut direction is changed when the line of cut of λ is less than or equal in the absence of axial numerical value in line of cut to be cut.Change cutting side
Backward, the end points nearest from tool position is selected from the candidate endpoint for meeting cut direction of line of cut to be cut under
(when choosing next cutting point after change cut direction, a plurality of conllinear line of cut is considered as one and cuts the cutting point once cut
Secant)；After having cut A → B, continue to cut C → D in a same direction；Change cut direction, cut E → F；Change cutting
Direction, cuts G → H；Change cut direction, select the I point nearest from H end points as the starting point cut next time, cut I → J,
Then the smaller K → L of axial numerical value where cutting, then cuts M → N.The cutting of all longitudinally cutting lines is completed again, is cut suitable
Sequence is A → B, C → D；E→F；G→H；I → J, K → L, M → N；O → P, Q → R.
(3) after completing the cutting of all transverse direction (longitudinal direction) lines of cut, from all longitudinal direction (transverse direction) cutting line endpoints to be cut
The middle cutting for selecting the end points nearest from cutter to start longitudinal direction (transverse direction) line of cut as the starting point cut next time.If nearest
End points be in the right side of Layout (on) half part, then the reverse direction for changing x-axis and y-axis, is then carried out according to the rule in (2)
Cutting.The cutting sequence of longitudinally cutting line is S → T, U → V；W→X；Y→Z；a→b.
The two-dimensional rectangle part interactive mode sample layout optimizing method based on group change technology that the present invention is provided, rectangular-shaped piece blanking process
In the problems such as consider subsequent technique, workshop transport, Job-Shop, it is also contemplated that the Utilizing question of remaining white space after stock layout
The problem cut into slices with raw material fault Avoidance and interim addition, and man-machine interactive Cutting Stock Problem is solved, and
