The following detailed description of the embodiments of the present invention will be provided with reference to the accompanying drawings and examples, so that how to implement the embodiments of the present invention by using technical means to solve the technical problems and achieve the technical effects can be fully understood and implemented.
The embodiment of the invention is mainly applied to the field of numerical control machining, in particular to product machining in the 3C industry.
The current product processing mode usually adopts reverse thinking, as described in the background art, a product model is obtained through analysis and processing of a target product, and then a numerical control processing program is obtained based on the product model. However, the inventor finds that, in the research, when the numerical control machining program is used for controlling the machining machine to machine the product, the product is easy to have the abnormal phenomenon, the finished product rate of the machined product is low, and the machining efficiency is low.
The inventor discovers through a series of researches that the main reason for the appearance of product abnormity in the product processing process is when product modeling is carried out, errors easily occur in a curve formed by dot matrix data, and the curve is led to exist an abnormal curve, and the surface and the body of the abnormal curve have problems, and further the product model has errors, and the errors also occur in a cutter and a cutter path arranged based on the product model, and further the numerical control processing machine is led to have a cutter path abnormity in the product processing process, for example, the phenomena of cutter jump or cutter path repetition and the like, so that the processed product which is led to finally output has abnormity and the like.
In the embodiment of the invention, a modeling object is obtained by analyzing the source numerical control machining program, and the target product is reversely modeled to obtain the machining data of the target product. After a modeling object is obtained, a special-shaped object in the modeling object can be determined, the special-shaped object is corrected to obtain a corrected object, the source numerical control machining program is updated based on the corrected object to obtain a target machining program, and a target product with a good machining effect can be obtained when the target machining program is used for machining a product, so that a target product with a good appearance can be obtained.
By the technical scheme of the embodiment of the invention, the source numerical control machining program can be verified and updated after the source numerical control machining program is generated, so that the phenomenon that the machined product obtained by directly utilizing the source numerical control machining program is in a product abnormal shape is avoided, and certainly, the source numerical control machining program can be updated when the machined product obtained by utilizing the source numerical control machining program is in a product abnormal shape, so that the machined product is regenerated by utilizing the obtained target machining program. Of course, the technical solution of the embodiment of the present invention is not limited to the above two application scenarios.
The technical solution of the present invention will be described in detail below with reference to the accompanying drawings.
Fig. 1 is a flowchart of an embodiment of a product processing method according to an embodiment of the present invention. The method may comprise the steps of:
101: and analyzing the source numerical control machining program of the target product to obtain a modeling object.
The source numerical control machining program refers to a program which can be input into a numerical control machining machine to machine a product, and the generation method of the source numerical control machining program is the same as that of the prior art, namely, the machining tool and the machining tool path which are set based on a product model can be generated. The specific generation mode can comprise two types, wherein one type is written by a worker in advance, and the second type is generated by the worker by using an engineering aided design system. The engineering aided design system may be constituted by drawing software, UG (Unigraphics N) software, PowerMill software and other software with computer aided design function, such as AutoCAD (automatic computer aided design) software.
The source nc machining program may be a file having a specific format that may be determined according to a file receivable by the nc machining machine, for example, the source nc machining program may be a dat file, a txt file, or the like.
As an embodiment, the parsing the source nc processing program of the target product to obtain the modeled object may include:
and calling an engineering aided design system to analyze a source numerical control machining program of the target product so as to obtain a modeling object.
Since the body of the product model is composed of surfaces, the surfaces are composed of curves, and the curves are composed of points, the target product is based on curves during processing, and the modeling object can specifically refer to curves required for modeling.
And after the source numerical control machining program is analyzed, the dot matrix data of the target product can be obtained. The lattice data is composed of multi-level and multi-dimensional points to form the shape of a product model. The modeled object may be obtained by curve-modeling the lattice data, which is a curve in a broad sense and may include straight lines or line segments. The modeled object may exist in two-dimensional or three-dimensional form.
Thus, as yet another embodiment, the parsing the source nc processing program of the target product to obtain a modeled object may include:
analyzing a source numerical control machining program of the target product to obtain dot matrix data of the target product;
and performing curve modeling on the dot matrix data to obtain the modeling object.
There are various specific ways to curve-shape the dot matrix data, and two possible implementation ways are listed below:
the first method may use a curve modeling manner provided by an engineering aided design system to perform curve modeling to obtain a modeling object, for example, the curve modeling manner may be spline modeling.
And secondly, introducing plug-ins or third-party software into the engineering aided design system, and performing curve modeling through the plug-ins or the third-party software to obtain the modeling object, wherein the curve modeling mode can be curve fitting, for example.
Therefore, the curve modeling of the dot matrix data may include: and carrying out spline modeling on the dot matrix data or carrying out curve fitting on the dot matrix data.
102: a shaped object of the modeled objects is determined.
Optionally, the determining of the heteromorphic object in the modeled object comprises:
any one of the repetitive objects and/or the interrupt object in the modeling object is taken as a heteromorphic object. The irregular object may also be an object that is bent, for example, the middle of a curve of a certain arc shape is bent.
For convenience of understanding, as shown in fig. 2a, the modeled objects 202 and 202 obtained after the source nc processing program of the target product 201 analyzes obviously include the irregular object 2021, and after the irregular object 2021 is enlarged, the irregular object 2021 may be specifically the irregular object 2021 with the interruption as shown in fig. 2 b. And as shown in the dashed box in fig. 3a, the heteromorphic object 301 is a heteromorphic object in which repetition and interruption occur.
The interruption object may be a phenomenon that a continuous curve in the modeling object is interrupted and is no longer a continuous curve. The irregular object may be a phenomenon that a curve in the modeling object is curved, unsmooth, or the like.
Therefore, as another embodiment, after the modeling object is obtained, the modeling object can be output, so that the user can conveniently check the modeling object to find the abnormal object with the problem.
Thus, the determining of the heteromorphic object in the modeled object may comprise:
in response to a user selection operation for the modeled object, determining a selected heteromorphic object;
when the user finds the special-shaped object in the modeling object by looking up the modeling object, the user selection operation can be triggered to select the special-shaped object.
103: and correcting the special-shaped object to obtain a corrected object.
As a further embodiment, said modifying said profiled object to obtain a modified object may comprise:
determining lattice data for constructing the special-shaped object;
deleting the special-shaped object;
and reconstructing the modified object according to the lattice data for constructing the special-shaped object.
The constructing of the dot matrix data of the special-shaped object may include dot data at both ends of the special-shaped object and a plurality of dot data between both ends, and the deleting of the special-shaped object may refer to deleting a connection relation of the dot matrix data constituting the certain object, instead of deleting the dot matrix data constituting the special-shaped object, so that the modified object may be reconstructed based on the dot matrix data constituting the special-shaped object.
The reconstructing of the modified object may be bridging the lattice data for constructing the special-shaped object to form a modified object meeting a preset requirement according to the lattice data for constructing the special-shaped object.
When the modeling object is a modeling curve, the special-shaped object is also a special-shaped curve in the modeling curve, and the lattice data is bridged to form a smooth and flexible curve.
Of course, instead of deleting the whole abnormal object, only the line segment of the abnormal object with the abnormal problem may be modified.
Further, as still another embodiment, the modifying the heteromorphic object to obtain a modified object may include:
and modifying the special-shaped object to obtain a modified object in response to the user modification operation aiming at the special-shaped object.
Alternatively, the special-shaped object may be deleted and the modified object may be reconstructed according to the lattice data for constructing the special-shaped object by a corresponding user modification operation for the special-shaped object.
When the special-shaped object is a special-shaped curve and the modified object is reconstructed, the dot matrix data can be bridged by manual control to form the modified object meeting the preset requirement.
And correcting the special-shaped object to obtain a corrected object meeting preset requirements. The modified object 2022 shown in fig. 2c is generated after the modification of the shaped object 2021 shown in fig. 2a, and the modified object 302 shown in fig. 3b is generated after the modification of the shaped object 301 shown in fig. 3 a.
104: and updating the source numerical control machining program to obtain a target machining program based on the corrected object.
The updating of the source nc machining program may refer to modifying the source nc machining program or regenerating the machining program. After the irregular object is updated to be the correction object, the modeling object can contain the correction object.
Therefore, as an embodiment, the updating the source nc machining program to obtain the target machining program based on the correction object includes:

Further, as still another embodiment, the generating of the target machining program according to the modeled object after the updating may include:
setting a machining tool and a machining tool path according to the updated modeling object;
and generating the target machining program according to the machining tool and the machining tool path.

The target processing program may be a control instruction for the processing tool to process the target product in the numerical control machine according to the processing tool path.
105: and processing the product based on the target processing program.
The target processing program can be input into the numerical control machine to process a target product, and the numerical control processing machine executes the target processing program, so that the product processing can be carried out, and a processed product can be obtained.
In the embodiment of the invention, the source numerical control machining program of the target product is analyzed, the target product is actually subjected to reverse reconstruction to obtain the modeling object of the target product, and then the special-shaped object in the modeling object can be corrected to obtain the corrected object, so that the machining program of the target product can be updated to be the target machining program based on the corrected object, the machining program can be used for machining the target product through the target product machining program, the machining problems of special shapes, rotten surfaces and the like in the source numerical control machining program are solved, and the machining efficiency of the product is improved.
