3) in Mathematical Modeling, intersect with shape in XZ plane and the part, obtain minimum two characteristic face I of this direction, the spacing of adjacent characteristic face I is N; Intersect with shape in YZ plane and the part, obtain two minimum characteristic face II of this direction, the spacing of adjacent characteristic face II is N; The characteristic face I is intersected with the characteristic face II is orthogonal;
4) in Mathematical Modeling; With the interior shape of part to be processed and the characteristic face I between the fixed base plate and characteristic face II is the entity that benchmark forms assembled tool; With the characteristic face I is that the entity at center is horizontal support plate, is that the entity at center is vertical support plate with the characteristic face II;
5) every horizontal support plate with vertically be provided with draw-in groove on the support plate, laterally the draw-in groove of support plate upwards, vertically the draw-in groove of support plate is downward, laterally support plate is connected through draw-in groove with vertical support plate, the intersection between draw-in groove is the intersection of characteristic face I and characteristic face II in the Mathematical Modeling;
6) bottom surface at every horizontal support plate and vertical support plate is provided with attachment lug, and the position of attachment lug is corresponding with the cross bore position of working plate, and width is corresponding to the groove size with length and cross recessed folk prescription;
7) obtain the concrete size of every horizontal support plate and vertical support plate after, in mathematical model, form the DXF formatted file, and handle redundant line, form the face territory;
8) utilize the DXF file that forms in the laser cutting machine program editing Mathematical Modeling, cut out every horizontal support plate and vertical support plate then;
9) horizontal support plate and vertical support plate are pegged graft, and simultaneously and working plate peg graft, obtain assembled tool, part to be processed is placed on it carries out cut and get final product.
The processing method of the cut assembled tool of this Mathematical Modeling adopts above-mentioned steps, can in production procedure, reduce design and manufacturing operation that multidisciplinary cooperation could be accomplished, has also therefore reduced the production cycle, has improved production efficiency.Employing has the cross recessed working plate, and the program after the cutting can directly be used next time, and datum mark etc. is prepared frock once more.The frock of this connected structure greatly reduces the material of frock, has reduced the cost of frock.
