[0033] In order to more clearly describe the technical content of the present invention, further description is given below in conjunction with specific embodiments.

[0034] The method for implementing tool path planning processing for a glass four-blade cutting machine of the present invention comprises the following steps:

[0035] (1) Import metadata;

[0036] (2) Input tool parameters;

[0037] (3) Planning tool paths;

[0038] (4) Output tool path file;

[0039] (5) The CNC system loads and analyzes the machining files generated by CAM and performs machining.

[0040] As a preferred embodiment of the present invention, the step (3) specifically comprises the following steps:

[0041] (3.1) Sort the input graphics by Y axis and select graphics with consistent Y coordinates;

[0042] (3.2) Find similar graphics;

[0043] (3.3) Group similar graphics;

[0044] (3.4) Assign tools to grouped graphics.

[0045] As a preferred embodiment of the present invention, the step (3.3) specifically includes the following steps:

[0046] Group similar graphics and determine whether the spacing between graphics in the group is greater than or equal to the minimum spacing of the tool head. If so, proceed to step (3.4); otherwise, continue to group similar graphics.

[0047] As a preferred embodiment of the present invention, the step (3.4) specifically includes the following steps:

[0048] (3.4.1) Filter the combinations that do not meet the minimum spacing between the tools;

[0049] (3.4.2) Filter combinations with insufficient tool travel;

[0050] (3.4.3) Calculate the tool's idle travel distance;

[0051] (3.4.4) Calculate the tool idle travel distance, obtain the tool combination with the shortest tool idle travel distance, and assign tools to the grouped graphics.

[0052] As a preferred embodiment of the present invention, the calculation of the tool idle travel distance in the step (3.4.4) is specifically as follows:

[0053] The tool idle travel distance is calculated according to the following formula:

[0054] Tool idle movement distance = the distance the machining tool moves from the current position to the starting point of the graphic + the distance the non-machining tool moves from the current position to the avoidance position.

[0055] The device for implementing tool path planning processing for a glass four-blade cutting machine of the present invention comprises:

[0056] a processor configured to execute computer executable instructions;

[0057] The memory stores one or more computer executable instructions. When the computer executable instructions are executed by the processor, the steps of the above-mentioned method for realizing tool path planning processing for a four-blade glass cutting machine are implemented.

[0058] The processor of the present invention is used to implement tool path planning processing for a four-blade glass cutting machine, wherein the processor is configured to execute computer executable instructions. When the computer executable instructions are executed by the processor, the various steps of the above-mentioned method for implementing tool path planning processing for a four-blade glass cutting machine are implemented.

[0059] The computer-readable storage medium of the present invention stores a computer program thereon, and the computer program can be executed by a processor to implement the various steps of the above-mentioned method for implementing tool path planning processing for a four-blade glass cutting machine.

[0060] In a specific embodiment of the present invention, a tool path planning strategy for a CAM software of a glass four-blade cutting machine is proposed, which inputs any graphic element, searches for similar graphics, plans a multi-blade collaborative processing path, and improves processing efficiency.

[0061] The overall process of the present invention is as follows:

[0062] Import DXF files or draw primitives. CAM software will plan the actual tool path based on the primitive information and meet certain physical conditions. The overall steps are as follows:

[0063] 1. Import metadata;

[0064] 2. Input tool parameters, such as the minimum spacing of the tool head;

[0065] 3. Plan tool path;

[0066] 4. Output tool path file;

[0067] 5. The CNC system loads and analyzes the processing files generated by CAM for processing.

[0068] like Figure 1 As shown in the figure, the specific process of planning strategy is as follows:

[0069] 1. Sort the input graphics by Y axis:

[0070] Through this step, the graphics with consistent Y coordinates can be screened out.

[0071] 2. Find similar graphics:

[0072] Input two figures with the same Y coordinates, translate the figure on the right to the position of the figure on the left, and the two figures completely overlap, which means they are similar figures.

[0073] 3. Grouping of similar graphics:

[0074] The graphics in a group can be processed at the same time, so when grouping, try to make the number of groups reach 4. Grouping conditions: The spacing between graphics in a group must be greater than or equal to the minimum spacing between tool heads.

[0075] Take three similar figures as an example, from left to right they are Element 1, Element 2, Element 3, and the minimum tool spacing is 100:

[0076] The spacing between primitive 1 and primitive 2 is 90, and the spacing between primitive 2 and primitive 3 is 90. At this time, the spacing between primitive 1 and primitive 2 is too small, and the spacing between primitive 2 and primitive 3 is too small, and they cannot be processed at the same time.

[0077] The distance between element 1 and element 3 is 180, which can be processed by tool 1 and tool 3. Therefore, element 1 and element 3 are grouped together, and element 2 is grouped together.

[0078] 4. Assign tools to grouped graphics:

[0079] There may be multiple tool combinations when allocating tools. You need to select the combination with the shortest tool idle movement distance. The process is as follows:

[0080] 1. Filter the combinations that do not meet the minimum spacing between the tools;

[0081] 2. Filter combinations with insufficient tool travel;

[0082] 3. Calculate the tool's idle travel distance;

[0083] 4. Choose the tool combination with the shortest moving distance.

[0084] The tools involved in processing are called processing tools, and the tools not involved in processing are called non-processing tools.

[0085] Tool idle movement distance = the distance the machining tool moves from the current position to the starting point of the graphic + the distance the non-machining tool moves from the current position to the avoidance position.

[0086] The spacing between the four glass cutting heads is dynamic and can move freely in the X direction as long as it does not touch other cutting heads or exceed the upper and lower limits of the cutting head travel.

[0087] Among the four glass cutting heads, determining the processing cutting head requires multiple steps:

[0088] 1. Determine whether the graphic spacing meets the requirements for multi-tool processing;

[0089] 2. Determine whether the cutter head stroke is sufficient;

[0090] 3. It is necessary to screen the best tool combination (the distance the tool moves from the current position to the starting point of processing).

[0091] The specific implementation scheme of this embodiment can refer to the relevant description in the above embodiment, which will not be repeated here.
