All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The first embodiment is as follows:
fig. 1 is a flowchart of a method for optimizing a processing path according to an embodiment of the present invention, where the method includes the following steps:
step S12, obtaining original machining data of a plurality of parts to be machined, where the original machining data includes: original processing side information and the processing times of each processing side, wherein the original processing side information at least comprises: the vertex coordinate information of the part to be machined and the edge information of the part to be machined, and the machining edge is determined by the original machining edge information.
Specifically, to process and produce a to-be-processed part on a to-be-processed raw material, in order to plan a processing path, first, original processing data of the to-be-processed part needs to be acquired, where the original processing data includes: the method comprises the steps that original processing side information and the processing times of each processing side are obtained, wherein each piece of original processing side information comprises vertex coordinate information of a processing side of a part to be processed on a raw material to be processed, shape parameters of the side and other information, and the position of the processing side on the raw material to be processed can be determined according to the original processing side information; in addition, depending on the characteristics of the material to be processed, such as thickness or material, the processing tool may be required to perform reciprocating cutting on the processing edge, so as to achieve the processing edge meeting the quality standard.

And step S18, determining an optimized processing path for processing a plurality of parts to be processed according to the target processing side information.

The above briefly introduces the method for optimizing a machining path in the embodiment of the present invention, and the following describes in detail specific contents of determining an optimized machining path for machining a plurality of parts to be machined according to target machining-side information.
In an alternative embodiment, as shown in fig. 2, determining an optimized machining path for machining a plurality of parts to be machined according to the target machining side information includes the following steps:
and step S181, classifying the plurality of parts to be machined based on the target machining side information and the preset size standard, and determining a first part to be machined and a second part to be machined, wherein the first part to be machined is a part to be machined corresponding to the target machining information which is not higher than the preset size standard, and the second part to be machined is a part to be machined corresponding to the target machining information which is higher than the preset size standard.
Specifically, after the target processing side information is obtained, classifying a plurality of parts to be processed according to a preset size standard, confirming the size of the shortest processing side of each part to be processed according to the target processing side information, and if the size of the shortest processing side is not higher than the preset size standard, calling the part to be processed as a first type of part to be processed; conversely, if the size of the shortest machining edge of the part to be machined is higher than the preset size standard, the part to be machined is referred to as a second type of part to be machined.
Step S182, determining the processing path of the first type of parts to be processed based on the target processing side information of the first type of parts to be processed to obtain a first processing path.
When planning the machining path of the machining tool, a first machining path of the first type of part to be machined is first determined based on the target machining side information of the first type of part to be machined, and a determination process of the first machining path will be described in detail below.
And step S183, determining the machining path of the second type of parts to be machined based on the target machining side information, and obtaining a second machining path.
After the first type of part to be machined with a relatively small size is machined, a second machining path of the second type of part to be machined is determined based on the target machining side information, and a determination process of the second machining path will be described in detail below.
Step S184 is executed to set the first machining route and the second machining route as the optimized machining route.
The planning of the optimized machining path is briefly described above, and the process in which the first machining path is determined is described in detail below.
In an optional embodiment, the step of determining the machining path of the first type of part to be machined based on the target machining side information of the first type of part to be machined comprises the following steps:
step S1821, determining the adsorption force of the first type of parts to be machined and the tool drop point of the first type of parts to be machined during machining based on the target machining side information of the first type of parts to be machined.
Specifically, in the machining process, the adsorption force of each first type of part to be machined and the tool drop point of each first type of part to be machined during machining are calculated according to the size of the first type of part to be machined (target machining side information of the first type of part to be machined).
In calculating the adsorption force of each first type of part to be machined, various ways can be adopted, the invention is not limited to the method, and for the convenience of understanding, a calculation method which can be realized in the method is exemplified as follows:
firstly, calculating the distance between the center of each first type of part to be machined and the center of the raw material to be machined according to the target machining side information, and taking the reciprocal of the obtained distance to use the reciprocal as the offset coefficient of each first type of part to be machined, wherein obviously, the offset coefficient is smaller for the first type of part to be machined which is farther away from the center of the raw material to be machined.
And then determining the perimeter of each first type of part to be machined according to the target machining side information, multiplying the perimeter by the offset coefficient of the first type of part to be machined, and taking the obtained result as the adsorption force of the first type of part to be machined.
The tool drop point is an optimal machining starting position calculated for preventing the first type of parts to be machined from shifting in the machining process, and the problem of tool drop point of the parts to be machined with larger size does not exist. In the embodiment of the invention, the selection process of the tool drop point of the first type of part to be machined is as follows, taking one first type of part to be machined as an example:
firstly, the longest machining edge in the adjacent machining edges is determined according to the machining edge information of the first type of part to be machined, and then the last machining edge of the first type of part to be machined is the machining edge adjacent to the longest machining edge.
If the preset processing sequence is anticlockwise processing, one of two vertexes of the last processing edge is selected as a tool drop point of the first type of part to be processed according to actual conditions, so that the processing edge is processed finally, and therefore the first type of part to be processed with a smaller size has an attachment relation with a raw material to be processed, is not isolated and is not easy to shift.
Step S1822, determining a processing sequence for processing the first type of parts to be processed based on the adsorption force of the first type of parts to be processed.
Further, after the adsorption force of each first type of part to be machined is determined, the first type of parts to be machined are sequenced according to the adsorption force, the first type of part to be machined with the minimum adsorption force is machined firstly, the first type of part to be machined with the maximum adsorption force is machined last, and the machining sequence for machining the first type of parts to be machined is determined according to the machining principle.
And step S1823, determining a first processing path based on the processing sequence, the cutting point and the processing side information of the first type of parts to be processed.
Further, according to the calculated cutting point of each first type of part to be machined and the machining side information of each first type of part to be machined, a machining path of the machining tool in machining each first type of part to be machined can be obtained, and then according to the determined machining sequence, the first machining path of the first type of part to be machined can be obtained, wherein when the first type of part to be machined is machined, machining in the anticlockwise direction from the cutting point is set, in the actual machining process, a user can also set machining in the clockwise direction, and then the selection of the cutting point needs to be changed along with the change, so that the machining direction is not limited. When the cutting end point of the previous part to be machined is different from the starting point of the next part to be machined, the machining cutter needs to be controlled to lift from the cutting end point of the previous part to be machined, the machining cutter is controlled to be directly switched to be above the starting point of the next part to be machined, then the cutter is dropped, and then machining is continued.
The process of determining the first machining path is described in detail above, and the process of determining the second machining path is described in detail below.
In an alternative embodiment, as shown in fig. 3, determining the machining path of the second type of part to be machined based on the target machining-side information includes the following steps:
step S1831 is to delete the processing side information corresponding to the first processing route from the target processing side information, and obtain the remaining processing side information.
Specifically, the machining path of the first type of part to be machined has been planned, and then the machining side information of the first type of part to be machined is removed from the target machining side information to obtain the remaining machining side information, so that all the second type of parts to be machined can be finally obtained as long as the machining tool traverses the machining path determined by the remaining machining side information, it should be noted that the remaining machining side information is not necessarily all the machining side information of the second type of part to be machined, because if there is a machining side that overlaps with the second type of part to be machined in the first type of part to be machined, the machining path corresponding to the overlapping machining side already belongs to the first machining path.
Step S1832, the remaining processing side information is processed by using the euler loop algorithm to obtain an euler path.
The euler loop algorithm is widely applied in various fields, the euler loop algorithm is utilized by the invention to obtain the minimum cutter lifting times of the machining cutter, because the processes of cutter lifting, cutter transferring and cutter falling are very time-consuming in the machining process, after the residual machining side information is obtained, the residual machining side information is processed by utilizing the euler loop algorithm to obtain an euler path, the euler path is a machining path which passes through each machining side determined by the residual machining side information and passes through each machining side only once, the euler path can be equal to a path which is machined without cutting according to a single part in the machining process of a second type of part to be machined, but can be cut once under the condition of not lifting the cutter as far as possible, but if one euler path can not contain all the residual machining side information, then step S1833 will be performed.
In step S1833, if there are a plurality of euler paths, it is determined whether or not there is any processing-side information connecting the euler paths in the target processing-side information.
Specifically, if there are a plurality of euler paths, that is, the remaining processing paths determined by the processing edge information cannot be cut, at this time, the processing tool needs to be switched from one euler path to the next euler path, and in order to achieve the purpose of not lifting the tool as much as possible, it needs to determine whether there is processing edge information connected to the euler path in the target processing edge information, and the processing tool preferentially considers the processing path determined by the existing processing edge information in the switching process between the euler paths.
In step S1834, if there is any, the shortest processing side information is determined from the processing side information of the euler paths, and the processing path corresponding to the shortest processing side information is used as the switching path between the two euler paths.
If there is processing side information connecting euler paths and there are a plurality of such processing paths, in order to improve processing efficiency and shorten processing time, the shortest processing side information is determined from the processing side information connecting euler paths, and the processing path corresponding to the shortest processing side information is used as a switching path between two euler paths, it should be noted that the shortest processing side information may be not only one piece of processing side information, but also more likely to be composed of a plurality of pieces of processing side information.
In step S1835, the euler path and the switching path are used as the second processing path.
In an alternative embodiment, the material of the plurality of parts to be machined includes: the wood and the parts to be machined comprise the parts to be machined of the wood.
Specifically, the machining path optimization method provided by the embodiment of the invention can be applied to the field of wood machining, because wood machining is contact machining, parts to be machined of wood are divided into a large plate and a small plate according to a wood machining process when a machining sequence is output, wherein the standard of the small plate is set by a factory according to the actual condition of equipment. The adsorption power of big board, platelet will be calculated according to big board and little board size in the course of working, and the adsorption power of general platelet is less, and the adsorption power of big board is great, and the plate can not appear in the course of working in the big board and shift.
After having distinguished big slabstone, will arrange the preferential processing of platelet, prevent to appear running the board phenomenon, the cutting of platelet will calculate the cutting point of processing sword, calculates the cutting route of platelet according to the cutting point, and wherein, the cutting point is decided according to the adsorption affinity of platelet, guarantees that the platelet can not run the board in cutting process. And after the small plate is cut, cutting the rest large plate in an optional cutting mode, wherein the optional cutting is to calculate a shortest switching path which is not cut according to a single part to be processed but is cut once under the condition of not lifting the cutter as far as possible and cannot be cut completely, the shortest switching path preferably uses a path formed by the existing processing edge information, and if the switching path formed by the processing edge information does not exist, the processing cutter can only be lifted up and then directly switched to the next processing path.
According to the machining path optimization method provided by the invention, after the original machining data is obtained, the repeated machining side information is removed, the machining side information is reorganized to obtain the target machining side information, the machining priority order is determined according to the machining process rule, the machining path is optimized, the repeated side is cut once, and when switching is carried out among a plurality of Euler paths, the shortest path determined by the existing machining side information is used as the switching path of the machining cutter as much as possible, so that the cutter lifting times of the machining cutter can be effectively reduced, the machining path and the machining sequence are optimized on the whole, the machining efficiency is improved, the machining time is shortened, and the machining cost of a factory is reduced.
