Specific embodiment
In the following, being described further in conjunction with attached drawing and specific embodiment to the present invention, it should be noted that notUnder the premise of conflicting, new implementation can be formed between various embodiments described below or between each technical characteristic in any combinationExample.
A kind of special-shaped workpiece as shown in Figure 1 cuts modeling method, and detailed process further includes referring in Fig. 2 and Fig. 3Shown in threedimensional model, cutter model and sub- part model self-test structural schematic diagram, comprising the following steps:
Step S1, special-shaped workpiece dimension information and machining information are obtained, wherein machining information includes working depth and knifeHas offset type；In the present embodiment, special-shaped workpiece dimension information further include Workpiece length information and width of the workpiece information andWorkpiece height information；Machining information includes presetting cutter section, machining path information, working depth and tool offset type,In the present embodiment, it presets cutter section and machining path information is all the special-shaped workpiece that user needs to process according to oneselfWhat type was confirmed, the shape in cutter section can be it is varied, specifically set by user oneself, machining path information is to cutThe routing information cut specifically may include length and the radian of cutting path with etc. information can determine cutting by above- mentioned informationPath.
Step S2, threedimensional model 2 corresponding with special-shaped workpiece is constructed according to special-shaped workpiece dimension information；According to Workpiece lengthInformation, width of the workpiece information and workpiece height information structuring threedimensional model 2 corresponding with special-shaped workpiece.Specific is with abnormityWorkpiece size information information as a comparison makes in the dimension information of the threedimensional model 2 of construction highly not less than workpiece height, widthGreater than the width of the workpiece, length is greater than Workpiece length to get threedimensional model 2 shown in Fig. 2, the three-dimensional enumerated in the present embodiment is arrivedModel 2 is quadrilateral, the height of threedimensional model 2 otherwise be less than workpiece height, the width of threedimensional model 2 is greater than the width of the workpiece, threeThe length of dimension module 2 is greater than Workpiece length；The shape of threedimensional model 2 is chosen for the plate of positive tetrahedron in the present embodiment, toolThe shape of the threedimensional model 2 of body can carry out constructing according to the actual needs.
Step S3, by the default cutter section along the machining path information and the working depth construction path intoRow scans, and obtains cutter model 1；Specifically: three-dimensional is scanned according to default cutter section, machining path information and working depthModel 2 obtains 3D shape corresponding with the path that machining path information and working depth are constituted, using 3D shape as cutterModel 1, this cutter model 1 are the 3D shape in Fig. 2.
Step S4, boolean is carried out to the cutter model using the threedimensional model and subtracts processing, obtain sub- part model, thisIt is to carry out cutting process to threedimensional model that the boolean at place, which subtracts processing,.
Step S5, step S5 may include step S51 and step S52, step S51: judge tool offset type whether beOr whether working depth is less than the height of threedimensional model 2, if so, execute step S52, step S52: then using sub- part model asThe output of special-shaped workpiece model thens follow the steps S6 if it is not, sub- part model quantity is at least two.In the present embodiment, cutterOffset type can be in or left or right, specific criterion be using the initial position of machining path as reference direction, and withThe starting point of machining path as reference point, when residual paths relative to starting path in same straight line, then tool offset typeFor in, do not deviate as；Tool offset type in Fig. 3 is a left side, the starting path position 8 in Fig. 3, if residual paths are originatingWhen the left side of path position 8, then tool offset type is a left side, is as deviated to the left, i.e., as Figure 2-3；If residual paths existWhen originating 8 the right of path position, then tool offset type is the right side, is as deviated to the right.When tool offset type is middle, i.e. knifeThreedimensional model 2 is cut the cutting that do not shift by tool model 1, then obtains two sub- part models, and two sub- part models are equalIt is exported as special-shaped workpiece model.When working depth is less than the height of threedimensional model 2, i.e., cutter model 1 is not by three-dimensional mouldType 2 is cut, and the sub- workpiece of muti-piece will not be obtained when not cutting, can only obtain a sub- workpiece, as threedimensional model 2Body.
Step S6, effective sub- part model is filtered out in all sub- part models according to tool offset type as differentShape part model exports special-shaped workpiece model.Added in the machining path information with described according to the tool offset typeSeveral screening points are chosen at the edge of the path side of work depthwise construction, draw the line segment that length is preset length, house from screening pointThe sub- part model with line segment intersection is abandoned, using remaining sub- part model as special-shaped workpiece model.As shown in Figure 3, cutterThreedimensional model 2 is cut into the first sub- part model 3 and the second sub- part model 4 by model 1, and the cutter section in the present embodiment isDetermining 2-d plane graph is drawn with AutoCAD in advance, it is symmetrical with the Y-axis of AutoCAD two-dimensional coordinate system；In the present embodimentMachining path information and the edge of path side that constitutes of working depth choose several screening points, and a line segment is drawn with screening pointThe first line segment 5, second line segment 6, third line segment 7 in as Fig. 3 illustrate three line segments in Fig. 3, if substantially main lineSection, the first line segment 5, second line segment 6 and third line segment 7 are that the corresponding machining path information and the working depth constructPath one side edge in the corresponding line segment for screening point normal direction and making, in the present embodiment, for the ease of more understanding, andAll the line segment drawn will not needed all to mark in Fig. 3, is with cutter model 1 and cutter in the actual operation processDraw isometric line segment at equal intervals on the edge of the identical side of offset type, if discovery the second sub- part model 4 with it is upperState what any one line segment in the line segment of extraction intersected, then the second sub- part model 4 will be rejected at this time, the first sub- workpieceModel 3 is as special-shaped workpiece model and exports.In the present embodiment, preset length is that the half of 1 width of cutter model adds 1, shouldData are that can obtain by verification experimental verification；Second sub- part model 4 and the first above-mentioned line segment 5 in Fig. 3, second line segment 6 and theThree lines intersect, then give up the second sub- part model 4, retain the first sub- part model 3, and by the first sub- 3 conduct of part modelThe output of special-shaped workpiece model.
