Example Embodiment

[0033] Example 1

[0034] This embodiment uses 5000×3000×5 (mm) 45# steel plate as raw material, with an area of ​​14500mm respectively 2 , 11300mm 2 , 8400mm 2 , 7200mm 2 , 5600mm 2 , 4800mm 2 The panel parts to be processed are the object of description and describe the method of the present invention in detail:

[0035] Such as figure 1 As shown, a method for plate layout based on AutoCAD includes the following steps:

[0036] Step 1. Set the area to 14500mm according to the size 2 The part number graphic of the one, the area is 11300mm 2 The part number is figure two 2,......, and so on, the area is 4800mm 2 The part number is Figure 6 6;

[0037] Step 2: Draw the part graph 1 of the plate to be processed through AutoCAD software, and take the zero coordinate as the origin, and set the longest side A of graph 1 1 One end of the edge a 1 At the origin, set A 1 Place the edge on the X or Y axis, and draw a figure 1;

[0038] Step 3: Draw the drawing 2 of the plate part to be process...

Example Embodiment

[0046] Example 2

[0047] A method for discharging plates based on AutoCAD is basically the same as the first embodiment, the difference is that considering the loss of the corners of the parts due to cutting, the drawing size of this embodiment leaves a margin of 5-10mm when drawing graphics , To offset the loss caused by the cutting process.

Example Embodiment

[0048] Example 3

[0049] In the first embodiment, the graphs are arranged in order from large to small, and then the layout is performed according to the method of step 2 to step 6. However, since the figures are drawn in the order of different sizes, the results of the layout are not the same. The embodiment adds the steps of discharging optimization, which are specifically as follows:

[0050] First, calculate the remaining amount of material β when each graph is drawn in a different order, where the remaining amount of material β is the minimum value after the area of ​​the graph in Example 1 is arranged from large to small:

[0051]

[0052] Where S i Is the area of ​​each figure, n is the number of figures, this embodiment is 6, and i is the order number of each figure; therefore

[0053] The point with the largest absolute value of x in the coordinate values ​​of each graph is used as the parallel line of the Y axis, and the point with the largest absolute value of y in the c...

Abstract

The invention discloses an AutoCAD (Autodesk Computer Aided Design) based plate nesting method, belongs to the technical field of nesting before cutting of plates and solves the problems of many waste materials, severe waste and high cost of an existing plate cutting method. The method comprises steps as follows: a figure I, a figure II,...and the like of to-be-processed plate parts are drawn by AutoCAD software; the figure II, the figure III, the figure IV,... and the like are sequentially moved along the longest side and the movement stops until any one point in the figures contacts with other figures or X/Y axis, and figure data in a dwg or dxf format is generated; the figure data in the dwg or dxf format is imported into FastCAM software, and codes in an NC format are output through the FastCAM software; the codes in the NC format are input into a numerically-controlled machine tool, and plate cutting is executed. With the adoption of the method, leftover materials can be reduced maximally, so that the production cost is reduced, and plate materials are saved.

Description

technical field [0001] The invention belongs to the technical field of blanking before plate cutting, and in particular relates to a method for blanking blanks based on AutoCAD. Background technique [0002] Before the production and processing of the products, the factory needs to carry out the budget layout work on the panel materials to determine the quantity of raw materials consumed. Due to the different shapes of the parts, currently the layout is carried out by manual experience. The size of the discharge material is enlarged, resulting in a serious waste of raw materials, and the utilization rate of leftover materials is very low, so the production cost is extremely high. In the prior art, there are also methods of nesting using software, such as: [0003] Chinese Patent Application No. 201210568985.9, the patent document published on April 17, 2013, discloses an automatic and rapid discharge method for a sponge cutting machine. The steps are as follows: a. Base map...
