The analysis of 2.5D file of the present invention and the implementation step of routing algorithm can be:
1, the structural analysis of SLC file
In SLC file, contour layer data arrange according to strict tree.Owing to directly not describing the data of the section number of plies in SLC file, when reading outline data, need according to the thickness value in the quantity of the thick entry of change layer known in SLC file and every bar entry.If c is the quantity of threedimensional model layer; A is schedule of samples number of entries; N is the thickness of in schedule of samples entry i-th layer; Zi is the minimum Z axis value in schedule of samples entry in i-th entry, and Zmin is the Z axis value of feature bottom, and Zmax is the Z axis value at part top.The threedimensional model section number of plies is:
Then, read the number of sections of part top Z axis numerical value and physical model successively, finally read the model data of threedimensional model contour layer, after part one deck profile has read, redirect enters lower one deck until the digital independent of all layers is complete.
2, edge analysis
What profile divided is divided into following several situation:
I. profile normal or coincide with scan line.When profile is vertical with scan line, silhouette edge can represent with x=a (a is constant), only needs x=a and scan line to carry out simultaneous, obtain the coordinate value of intersection point when therefore calculating; When scan line and silhouette edge overlap, then 2 end points of taking this profile line segment are as the intersection point of silhouette edge and scan line.
Ii. extreme point and non-extreme point.In the process that scan line is intersected by silhouette edge, if the discontinuity point of scan line in profile, and silhouette edge appears at the same side of scan line, so claims these points to be extreme point; If silhouette edge appears at the not homonymy of scan line, so these points become non-extreme point.If yj is the y coordinate value of extreme point; Yj-1, yj+1 are respectively the y coordinate value of 2 adjacent points.Because the decision condition of extreme point is that 2 silhouette edges of summit angle are in scan line the same side, so the y coordinate value of adjacent 2 points of extreme point must be greater than or less than the y coordinate value of extreme point simultaneously, i.e. (yj-yj-1) (yj-yj+1) 0.
Iii. recessed flex point.The feature of recessed flex point is the limit that summit is connected is horizontal sideline, and the interior angle (being positioned at the angle of polygonal region) in another sideline and horizontal sideline is greater than 180%.When point set arranged counterclockwise, recessed flex point appears in the concave point on border, and when point set arranged clockwise, recessed flex point appears in the salient point on border, and namely the clocking sequence at certain some place is in reverse to the clocking sequence of whole profile, and a wherein limit of point is horizontal sideline.Recessed flex point can regard the special circumstances in extreme point situation as, when friendship is asked on scan line and limit, respectively with 2 limit find intersections of recessed flex point, obtains 2 identical intersection points.
Just can be analyzed the Linear cut situation of certain profile by the analysis of above situation of the same race, then by algorithm, analyze the path planning realizing current layer, generate machining path.
As shown in Fig. 7,8,9,10, for the realization of machining path on equipment.Because the particularity of stepper motor, the acceleration and deceleration curves of control need adopt S type curve.This is more difficult realization on traditional controller, all adopts DSP with being curve controlled device habitually in the past.Native system utilizes the DSP storehouse of STM32F407, achieves the curve controlled of stepper motor, and Fig. 7-10 is depicted as the existing curve of acceleration and deceleration place in several situation.The curve that motor accelerates is more level and smooth, and the velocity variations of motor is more steady, and the error caused is less, and is of value to the life-span of motor and reduces vibration.When upper figure lists several acceleration change, the situation of change of rate curve.In figure, ' a ' is acceleration change curve, and ' v ' is speed change curves.In situation shown in Fig. 7 and Fig. 9, stroke is shorter, and the time that can accelerate is short, level and smooth in order to ensure accelerator, is calculated by algorithm, make speed change curves can with setting the most at a high speed for summit smooth excessiveness.The stroke of Fig. 8 and Figure 10 is longer, and the time that can accelerate is also longer, and therefore, after reaching command speed, motor can enter the stage of deceleration again with the stroke that the speed even running of specifying is certain.From tracing analysis, Fig. 9,10 acceleration change process more steady, therefore when the acceleration time is identical, Fig. 9,10 accelerator relative to 7,8 comparatively level and smooth.Figure is several situations of resolving motor acceleration and deceleration, and actual acceleration and deceleration parameter is determined because of the length of stroke.
During the invention process, on data receiver, directly can receive CAD software hierarchy section file, emulated and machining path data directly can be imported to controller internal memory, convenient and practical.In data call, STM32F407 chip can be utilized fast to carry out system call and calculate control.Be directly output as electronic signal Driving Stepping Motor and light source carries out work.On Mechanical course, electronic pulse signal can be used to give light source and three axle system work orders, and be successively cured scanning, the front speed of service is faster than existing equipment.Frame for movement is set to three with parallel, and diaxon one is vertical, uses little a part of resin just can carry out work and resin utilization rate is 100%.In fineness: the type of our company's research and development can from 0.01 ~ 0.1mm, and other domestic similar type, from 0.06 ~ 0.1mm, improves 50%.Complete machine structure, complete machine can be Table top type structure, and adapts to different industries with being provided with different workbench 7 sizes.Material holds, and holding material is roundel charging tray 4, and effective rate of utilization is 4-10 times of conventional means.The injected volume that concrete equipment as shown in Figure 1 sets level the photosensitive resin 10 of material disc 4 can reach 2kg(and determine according to material disc 4 size), and as shown in Figure 5, by device inclined X angle, the resin thrown in can be made to taper to 100g; Other type domestic need be started working from 10KG at present, compares and saves Material Cost 90%.
