[0002] In the prior art, engraving machines are usually used to process three-dimensional stone parts, and milling cutters and forming cutters are used for layered cutting. Since the milling cutter has a limited single cutting range, the stone raw materials are usually large and not completely regular. Although it can complete the precise processing of complex irregular shapes, it has a low processing efficiency for simple and regular three-dimensional parts. In addition, the forming cutter has a high processing efficiency, but a single shape, and it also cannot meet the needs of customized processing. Summary of the invention

[0003] The purpose of the present invention is to overcome the disadvantages of the prior art and provide a method for quickly processing three-dimensional stone parts.

[0004] In order to achieve the above-mentioned purpose, the method of the present invention for realizing rapid processing of three-dimensional stone parts is as follows:

[0005] The method for realizing rapid processing of three-dimensional stone parts is mainly characterized in that the method comprises the following steps:

[0006] (1) Import custom dxf outline files and perform validity checks;

[0007] (2) configuring part parameter information according to the raw material length, raw material thickness, and workpiece thickness set by the user, and generating the corresponding part description;

[0008] (3) According to the selected process, the outer contour of the corresponding part is processed and sampling calculations for rough processing and fine processing are performed;

[0009] (4) According to the sampling points and workpiece size data, the three-dimensional coordinates are converted and the roughing tool path, the finishing tool path and the scraping tool path are generated respectively;

[0010] (5) Use the saw blade to start the machine tool according to the selected requirements and quickly process the raw materials.

[0011] Preferably, the step (1) is specifically as follows:

[0012] Import custom dxf outer contour files to obtain surface profile section data and thickness data of processed samples.

[0013] Preferably, the step (2) is specifically as follows:

[0014] The section validity detection and line planning are performed according to the raw material thickness and workpiece thickness set by the user, and the shape of the three-dimensional graphics is represented by the parameter information of the two-dimensional graphics and thickness length, so as to generate the corresponding part description.

[0015] Preferably, the step (3) is specifically as follows:

[0016] The profiling section is calculated based on the effective section data obtained from the raw material thickness and the workpiece thickness, and the corresponding processing steps are selected to perform section sampling on the sample contour according to the rough machining parameters and the fine machining parameters, and the rough machining and fine machining starting points are calculated respectively.

[0017] Preferably, the step (4) is specifically as follows:

[0018] According to the acquired processing starting point, profiling length and thickness parameters, the three-dimensional tool path coordinate information of the saw blade for rough processing, fine processing and scraping is calculated respectively.

[0019] Preferably, the step (5) is specifically as follows:

[0020] Use saw blades to perform corresponding processing on roughing tool paths, finishing tool paths and scraping tool paths according to the selected processing requirements to produce finished parts.

[0021] Preferably, the method adopts the same process in DXF outer contour file parsing and sampling for arc profiling, cross-section profiling, extrusion profiling and straight line profiling during the processing; wherein, the following differences are present in a single processing tool path:

[0022] The single roughing and finishing paths of linear profiling are straight lines, the single roughing and finishing paths of arc profiling are arcs, the single roughing and finishing paths of cross-sectional profiling are closed circles or rectangles, and the single roughing and finishing paths of extrusion profiling are straight lines or curves.

For regular three-dimensional workpieces, three-dimensional workpieces with customized contours can be processed according to customized cross-sectional outer contour dxf file information and part size information; at the same time, the processing efficiency can be improved and the processing cost can be saved. Customized processing of three-dimensional workpieces can be completed using only saw blades, which saves processing costs and effectively improves processing efficiency.

[0035] (2) configuring part parameter information according to the raw material length, raw material thickness, and workpiece thickness set by the user, and generating the corresponding part description;

[0036] (3) According to the selected process, the outer contour of the corresponding part is processed and sampling calculations for rough processing and fine processing are performed;

[0037] (4) According to the sampling points and workpiece size data, the three-dimensional coordinates are converted and the roughing tool path, the finishing tool path and the scraping tool path are generated respectively;

[0038] (5) Use the saw blade to start the machine tool according to the selected requirements and quickly process the raw materials.

[0039] As a preferred embodiment of the present invention, the step (1) is specifically:

[0040] Import custom dxf outer contour files to obtain surface profile section data and thickness data of processed samples.

[0041] As a preferred embodiment of the present invention, the step (2) is specifically as follows:

[0042] The section validity detection and line planning are performed according to the raw material thickness and workpiece thickness set by the user, and the shape of the three-dimensional graphics is represented by the parameter information of the two-dimensional graphics and thickness length, so as to generate the corresponding part description.

[0043] As a preferred embodiment of the present invention, the step (3) is specifically as follows:

[0044] The profiling section is calculated based on the effective section data obtained from the raw material thickness and the workpiece thickness, and the corresponding processing steps are selected to perform section sampling on the sample contour according to the rough machining parameters and the fine machining parameters, and the rough machining and fine machining starting points are calculated respectively.

[0045] As a preferred embodiment of the present invention, the step (4) is specifically as follows:

[0046] According to the acquired processing starting point, profiling length and thickness parameters, the three-dimensional tool path coordinate information of the saw blade for rough processing, fine processing and scraping is calculated respectively.

[0048] Use saw blades to perform corresponding processing on roughing tool paths, finishing tool paths and scraping tool paths according to the selected processing requirements to produce finished parts.

[0049] As a preferred embodiment of the present invention, the method adopts the same process in DXF outer contour file parsing and sampling for arc profiling, cross-section profiling and extrusion profiling and straight line profiling during the processing; wherein, there are the following differences in a single processing tool path:

[0050] The single roughing and finishing paths of linear profiling are straight lines, the single roughing and finishing paths of arc profiling are arcs, the single roughing and finishing paths of cross-sectional profiling are closed circles or rectangles, and the single roughing and finishing paths of extrusion profiling are straight lines or curves.

[0051] In practical applications, combined with Figures 2 to 7 As shown, this technical solution specifically includes the following steps:

[0052] It can be seen from the processed samples that the linear profiling is composed of two parts.

[0053] 1. Cross-section; 2. Length.

[0054] 1. Calculate DXF contour

[0055] like Figure 3 As shown, the planning is performed according to the raw material thickness and workpiece thickness set by the user. Here, two-dimensional graphics and parameter information such as thickness and length are used to represent the shape of the three-dimensional graphics;

[0056] 2. Sample the contour according to the roughing and finishing parameters, and calculate the starting points of roughing and finishing;

[0057] 3. If Figure 4 As shown, the three-dimensional tool path of the saw blade for roughing, finishing and scraping is calculated according to the starting point and the profiling length and thickness parameters;

[0058] 4. If Figures 5 to 7 As shown, a saw blade is used to perform rough machining, fine machining, scraping, and other processes according to selected requirements to produce finished parts.

[0059] 5. Arc profiling, cross-section profiling, and extrusion profiling use the same process as the straight line profiling solution in DXF parsing and sampling, but the single processing tool paths are different. The single rough and fine processing paths of straight line profiling are straight lines; arc profiling is an arc line; cross-section profiling is a closed circle or rectangle; and extrusion profiling is a straight line or a curve.

[0061] Step 1: Import the custom dxf outline file and perform validity check.

[0062] Step 2: Configure the part parameter information in the window and generate the part description.

[0063] Step 3: According to the selected process, the outer contour is processed and then the rough and fine processing sampling calculations are performed.
