The analysis of 2.5D file of the present invention and the performing step of routing algorithm can be:
1, the structural analysis of SLC file
In the SLC file, the profile layer data is arranged according to strict tree.Due to the data that there is no the Direct function description section number of plies in the SLC file, when reading outline data, need to be according to the bed thickness value in the quantity of change bed thickness entry known in the SLC file and every entry.If c is the quantity of threedimensional model layer; A is the schedule of samples number of entries; N is the bed thickness of i layer in the schedule of samples entry; Zi is the minimum Z axis value in i entry in the schedule of samples entry, and Zmin is the Z axis value of part bottom, and Zmax is the Z axis value at part top.The threedimensional model section number of plies is:
Then, read successively the number of sections of part top Z axis numerical value and physical model, read at last the model data of threedimensional model profile layer, after part one deck profile read and completes, redirect enters lower one deck until the data of all layers read complete.
2, edge analysis
Profile divides is divided into following several situation:
I. profile is vertical or coincide with scan line.When profile was vertical with scan line, silhouette edge can only need to carry out simultaneous with x=a and scan line when therefore calculating with x=a (a is constant) expression, obtains the coordinate figure of intersection point; When scan line and silhouette edge coincidence, take 2 end points of this profile line segment as the intersection point of silhouette edge and scan line.
Ii. extreme point and non-extreme point.In the process that scan line intersects by silhouette edge, if scan line through the discontinuity point in profile, and silhouette edge appears at the same side of scan line, claims so these points to be extreme point; If silhouette edge appears at the not homonymy of scan line, these points become non-extreme point so.If yj is the y coordinate figure of extreme point; Yj-1, yj+1 are respectively the y coordinate figure of adjacent 2 points.Because the decision condition of extreme point be 2 silhouette edges of summit angle in scan line the same side, so the y coordinate figure of adjacent 2 points of extreme point must be greater than or less than the y coordinate figure of extreme point simultaneously, i.e. (yj-yj-1) (yj-yj+1) 0.
Iii. recessed flex point.The feature of recessed flex point is that the limit that the summit is connected is horizontal sideline, and the interior angle in another sideline and horizontal sideline (being positioned at the angle of polygonal region) is greater than 180%.When point set was arranged counterclockwise, recessed flex point appeared in the concave point on border, and when the point set arranged clockwise, recessed flex point appears in the salient point on border, and namely the hour hands at certain some place sequentially are in reverse to the hour hands order of whole profile, and wherein limit of point is horizontal sideline.Recessed flex point can be regarded the special circumstances in the extreme point situation as, when scan line and limit are asked when handing over, with 2 limit find intersections of recessed flex point, has obtained 2 identical intersection points respectively.
Just can analyze the line cutting situation of certain profile by the analysis of above situation of the same race, then by algorithm, analyze the path planning of realizing current layer, generate machining path.
