The automatic programming method and the automatic programming system provided by the above embodiment of the invention have the following beneficial effects:
1. by receiving the information marked on the to-be-processed workpiece pattern by the user, the processing program of the to-be-processed workpiece can be automatically generated according to the to-be-processed workpiece pattern and the marked information, so that the time of a programmer is saved. The programmer does not need to manually write the processing program according to the workpiece to be processed, only needs to mark the corresponding processing characteristic information in the workpiece pattern to be processed, and the software can automatically generate the corresponding processing program after receiving the corresponding marked information.

Referring to fig. 1, an embodiment of the invention provides an automatic programming method. The automatic programming method comprises the following steps:
step S101: and acquiring a pattern of a workpiece to be processed. According to the requirement, the workpiece to be processed can be a welding angle seat, a pin seat, a connecting block, a vertical plate, an L-shaped integrated angle seat or a supporting pressing block and the like. In this embodiment, the workpiece to be processed is a connecting block.
Step S102: and according to the operation of a user, carrying out information marking on the pattern of the workpiece to be processed. According to the requirement, the marked information comprises one or more of pin holes, through holes, threaded holes and precision surfaces. It is understood that the labeled information may also include different types of grooves, cavities, chamfers, ribs, etc., and those skilled in the art may specifically set the information as needed.
Step S103: and generating a processing program of the workpiece to be processed according to the pattern of the workpiece to be processed and the marked information. According to the requirement, the processing program of the workpiece to be processed comprises information such as the setting of a tool path, the initial position of a tool and the like.
In the automatic programming method provided in the above embodiment, by performing information labeling on the to-be-processed workpiece pattern according to the operation of the user, the processing program of the to-be-processed workpiece can be automatically generated according to the to-be-processed workpiece pattern and the labeled information, thereby saving the time of a programmer. The programmer does not need to manually write the processing program according to the workpiece to be processed, only needs to mark the corresponding processing characteristic information in the workpiece pattern to be processed, and the software can automatically generate the corresponding processing program after receiving the corresponding marked information. The automatic programming method is convenient and quick, not only reduces the execution of mechanical repeated actions, but also reduces the programming time and errors of the machined parts, thereby realizing the quick programming of the machined parts.
Referring to fig. 2, in the present embodiment, the workpiece to be processed is a connecting block 100. The following describes an automatic programming method provided by an embodiment of the present invention by taking the connection block 100 as an example.
The connection block 100 includes a first side 110 and a second side 120. The first side 110 and the second side 120 are connected to each other and form a right-angled shape. In this embodiment, the first side 110 is a long side. The second side 120 is a short side. The first side 110 includes a first top surface 111, a first bottom surface 112, and a first outer side surface 113 and a first inner side surface 114 connected between the first top surface 111 and the first bottom surface 112. The second side 120 includes a second top surface 121, a second bottom surface 122, and a second outer side surface 123 and a second inner side surface 124 connected between the second top surface 121 and the second bottom surface 122. Specifically, the first top surface 111 and the second top surface 121 are flush with each other to form a top surface of the connection block 100. The first bottom surface 112 and the second bottom surface 122 are flush with each other to form a bottom surface of the connector block 100. The first side 110 is provided with a first hole 115, a second hole 116 and a third hole 117. In this embodiment, a first hole 115, a second hole 116, and a third hole 117 extend from the first outer side surface 113 to the first inner side surface 114. Specifically, the first hole 115 and the third hole 117 are pin holes, and the second hole 116 is a via hole, a waist hole, or a countersunk hole. The second side 120 is provided with a fourth hole 125, a fifth hole 126, a sixth hole 127 and a seventh hole 128. In this embodiment, the fourth hole 125, the fifth hole 126, the sixth hole 127 and the seventh hole 128 extend from the second outer side surface 123 to the second inner side surface 124. Specifically, the fourth hole 125 and the sixth hole 127 are standard coarse threaded holes; the fifth hole 126 and the seventh hole 128 are pin holes.
In the specific operation process, step S101 is first executed: and acquiring a pattern of a workpiece to be processed. That is, the three-dimensional pattern of the connection block 100 is opened in the design software.
Then, step S102 is executed: and according to the operation of a user, carrying out information marking on the pattern of the workpiece to be processed. That is, the programmer can mark the features on the workpiece pattern to be processed on the user interface of the design software.
Referring to fig. 3, in one embodiment, step S102 includes:
step S1021: displaying information to be marked;
step S1022: and associating the information to be marked with the characteristics on the workpiece to be processed according to the operation of the user.
I.e. a control with a feature label in the design software. After clicking the feature labeling control, the programmer can call up an interface for labeling the machining features of the connection block 100. As shown in fig. 4, in this embodiment, the labeled interface includes one or more of the following controls: pin holes, precision surfaces, through holes, threaded holes, and the like. Other types of controls can be added by those skilled in the art according to actual needs. For example, after clicking the control for the pin hole, click the first hole 115, the third hole 117, the fifth hole 126, and the seventh hole 128 in the connection block 100, i.e., representing the need to machine these holes into pin holes. For another example, after the control of the precision surface is clicked, the first outer side surface 113 and the second outer side surface 123 of the connecting block 100 are clicked, which means that the first outer side surface 113 and the second outer side surface 123 need to be processed into the precision surface. It will be appreciated that one of the ways of associating information to be noted with features on a workpiece to be machined is given above only schematically. In the actual application process, the information to be marked can be associated with the feature on the workpiece to be processed by clicking the feature to be processed on the connecting block 100 and then clicking the control on the marking interface.
Displaying information to be marked on an interface of software; and then associating the information to be marked with the characteristics on the workpiece to be processed according to the operation of the user. At this time, the process of marking the pattern of the workpiece to be processed becomes very simple. For example, pin holes, through holes, threaded holes or precision surfaces of the software can be displayed on the interface of the software for waiting for the marked information, and then the information to be marked is associated with the characteristics of the workpiece to be machined in a sequential clicking mode. Namely, the programmer can associate the information to be marked with the features on the workpiece to be processed by simple operation, so that the programming efficiency is further improved.
In fact, in order to facilitate the operation of the programmer, in one embodiment, step S102 further includes:
step S1023: the features on the workpiece to be machined are marked with a color.
In fact, in the design software, all features in the three-dimensional pattern of the connector block 100 are shown in gray as soon as the three-dimensional pattern of the connector block 100 begins to open. When the user clicks the control of the pin hole, the user clicks the first hole 115, the third hole 117, the fifth hole 126 and the seventh hole 128 in the connecting block 100, i.e. the holes need to be machined into pin holes. At this time, the first, third, fifth and seventh holes 115, 117, 126 and 128 in the connection block 100 are changed to blue. For another example, when the user clicks the control of the threaded hole, the fourth hole 125 and the sixth hole 127 are clicked, which means that the holes need to be machined into the threaded holes. At this time, the fourth and sixth holes 125 and 127 in the connector block 100 will become yellow. That is, if one or more holes in the workpiece to be machined are marked as pin holes, the machining features marked as pin holes in the workpiece to be machined will become displayed in blue after the marking is completed. Alternatively, if one or more faces of the workpiece to be machined are marked as precision faces, the machined features marked as precision faces in the workpiece to be machined will become displayed pink after the marking is completed. At this time, by marking the associated features on the workpiece to be processed with colors, a programmer can conveniently distinguish which processing features on the workpiece to be processed have been associated and which processing features have not been associated, thereby facilitating operation.
Referring also to fig. 5, in order to make the operation of the programmer more intuitive and simple, in one embodiment, in step S1023,
marking a first type of machining feature in a workpiece to be machined in a first color;
and/or marking a second type of machining feature in the workpiece to be machined in a second color;
and/or, marking a third type of machining feature in the workpiece to be machined in a third color.
The types of machining features include, but are not limited to, pin holes, through holes, threaded holes, precision surfaces, or the like. The selected color includes, but is not limited to, blue, pink, aqua, yellow, and the like. It is understood that the type of the processing feature may also be a chamfer or a circular arc surface, and the selected color may also be other colors such as cyan, green or purple, and the like, which can be specifically determined by those skilled in the art according to actual needs. In this embodiment, the pin holes are indicated in blue; the precision surface is marked with pink; the through holes are marked with precious green; the threaded hole is marked with yellow; the details are shown in the following table. For the non-processed surface, any color other than the above standard colors may be used. As shown in the table below, different types of holes are indicated using different colors. Wherein Ra is a mark symbol of surface roughness; H7/N7 is the dimensional tolerance symbol for the aperture. For example, Ra 3.2 represents that the surface unevenness of the workpiece to be machined has an average value of 3.2 micrometers with respect to the reference plane; ra 1.6 represents that the average value of the surface unevenness of the workpiece to be machined with respect to the reference plane is 1.6 μm.

That is, when marking a feature on a workpiece to be machined with a color, a machining feature of a first type in the workpiece to be machined may be marked with a first color; or marking a second type of machining feature in the workpiece to be machined in a second color; or a third type of machining feature in the workpiece to be machined is marked with a third color. For example, the pin holes are indicated in blue, the through holes are indicated in a precious green color, or the threaded holes are indicated in yellow. Because different types of machining features need to use different types of machining processes or different types of machining tools, the different types of machining features in the workpiece to be machined are marked by using different colors, and at the moment, the generated machining program of the workpiece to be machined is more accurate.
In fact, in order to make the operation of the programmer more intuitive. At the labeled interface, the name of the control can be defined as follows: pin hole (blue), precision face (pink), through-hole (precious green), threaded hole (yellow), undefined (grey). That is, the programmer can visually observe the color of the machining feature of the workpiece to be machined, which will change after clicking on the machining feature, at the marked interface. In one aspect, the programmer anticipates the color change of the machined feature during the labeling process. On the other hand, the name of the control corresponds to the color, so that the programmer can check whether the labeling error exists in the feature labeling process.
Further, in order to make the operation of the programmer more intuitive and convenient, in one embodiment, in step S1021,
displaying the information to be marked corresponding to the first type of processing characteristics by using a control with a first color;
and/or displaying the information to be marked corresponding to the second type of machining features by using a control of a second color;
and/or displaying the information to be marked corresponding to the machining features of the third type by using a control of a third color.
That is, at the labeled interface, the control of the pin hole (blue) is filled with blue; controls for the precision surface (pink) are filled in pink; the controls of the through holes (Bao Green) are filled with Bao Green; the threaded hole (yellow) controls are filled in yellow. The method can further enable a programmer to visually observe the color of the characteristic of the workpiece to be machined after the characteristic is marked, so that the subsequent checking and confirming process is facilitated.
It will be appreciated that in labeling machined features, there is no limitation on the order in which the individual machined features are labeled. The pin holes can be marked first, the threaded holes can be marked first, and the precision surface can be marked first. The technical personnel in the field can be specifically arranged according to the actual requirement.
After all the machining features are marked, the control of the program generation module can be clicked to generate the machining program of the workpiece to be machined. At this time, the design software performs step S103: and generating a processing program of the workpiece to be processed according to the pattern of the workpiece to be processed and the marked information.
In fact, in the pattern of the workpiece to be machined, information on the shape and size of the machined features, such as the diameter of the hole, the depth of the hole, the length of the groove, etc., has been included; in the process of marking the machining features, programmers define the types of the machining features in advance, such as threaded holes, through holes, precision surfaces and the like. At the moment, the design software can automatically select the CNC lathe, the machining tool or corresponding technological parameters according to different types of machining characteristics so as to automatically generate a machining program, and therefore programming efficiency is improved.
It can be understood that, in the actual machining process of the workpiece to be machined, the workpiece to be machined actually needs to be clamped by a clamp and then placed on a CNC lathe for machining. Therefore, in one embodiment, before step S103, the automatic programming method further includes any one or more of the following steps:
step S104: acquiring a clamp pattern according to a workpiece pattern to be processed;
step S105: and acquiring the cutter information and/or the lathe information according to the pattern of the workpiece to be processed and the marked information.
Referring to fig. 6, in the present embodiment, the clamp corresponding to the connecting block 100 is a clamp 200.
In step S104, a jig pattern corresponding to the workpiece pattern to be processed may be automatically acquired according to the workpiece pattern to be processed. On one hand, the method does not need a programmer to manually search the corresponding clamp pattern according to the workpiece pattern to be processed, so that the efficiency is improved. On the other hand, the workpiece pattern to be processed and the clamp pattern can be displayed on the display device at the same time, so that a programmer can conveniently confirm whether the used processing clamp pattern is accurate again.
In step S105, tool information and/or lathe information is acquired according to the pattern of the workpiece to be machined and the marked information. Likewise, the programmer no longer needs to manually find a suitable machining tool or machining lathe according to the pattern of the workpiece to be machined. The design software can automatically select proper tool information from a tool library which stores various tool information in advance, and automatically select proper lathe information from a lathe library which stores various machining lathes in advance, so as to be used for generating a machining program of a workpiece to be machined.
In one embodiment, in step S104,
and assembling the workpiece pattern to be processed into the clamp pattern according to the obtained clamp pattern.
On one hand, the clamping mode of the clamp to the workpiece to be machined influences the selection of a machining route of the cutter in the machining process and the like. Therefore, in the design software, the workpiece pattern to be processed is assembled into the clamp pattern according to the obtained clamp pattern, so that a programmer can judge the processing route map of the workpiece to be processed preliminarily, and subsequent inspection is facilitated. On the other hand, in the actual operation process of the workpiece to be processed, an operator of the processing equipment needs to clamp the workpiece to be processed by using the clamp. At this time, because the design software has assembled the to-be-machined workpiece pattern into the fixture pattern according to the acquired fixture pattern, it can output a fixture operation instruction according to the corresponding assembly mode to instruct an operator of the machining device to clamp the to-be-machined workpiece by using the fixture.
Referring to fig. 7, in an actual operation process, after the three-dimensional pattern of the connection block 100 is opened, the three-dimensional pattern of the clamp 200 corresponding to the connection block 100 may be automatically acquired by clicking a control button set by the clamp information. In this embodiment, the three-dimensional pattern data of the jig 200 may be placed in a local storage space of a computer or on a network server. When the programmer clicks to acquire the clamp information, the server can be accessed through a network, so that the three-dimensional pattern of the clamp stored on the network server is acquired. In fact, the design software stores in advance a mapping table between the workpiece to be machined and the fixture. One or a certain type of workpiece to be processed corresponds to one set of clamps. At the moment, a programmer clicks a control button set by the clamp information, and the system automatically searches the corresponding clamp information according to the name of the workpiece to be processed. For example, if the name of the workpiece to be machined is LJK-A-001, the jig type matching therewith can be accurately found from the name "LJK-A-001". For another example, if the name of the workpiece to be machined is LJK-a-002, and the workpiece to be machined LJK-a-001 and the workpiece to be machined LJK-a-002 can share the same set of jigs, then the jig type matching the name of the workpiece to be machined can be found according to the partial information "LJK-a" in the name of the workpiece to be machined. In practice, the suffix name of the drawing file is generally fixed for the three-dimensional pattern of the workpiece to be processed, such as ". step", or ". IGS", or ". X _ T", etc. At the moment, in the process of automatically searching the corresponding clamp information according to the name of the workpiece to be processed, the suffix name of the corresponding drawing file can be automatically omitted so as to improve the efficiency.
After acquiring the fixture information, the system also automatically pops up information on how the workpiece to be machined is fitted to the fixture, as needed. The information may be displayed on a display interface. At this time, the programmer can assemble the workpiece pattern to be processed and the fixture pattern together according to the corresponding display information.
Specifically, in the process of assembling the workpiece pattern to be processed and the fixture pattern together, the first positioning surface and/or the second positioning surface and/or the third positioning surface may be selected in the workpiece pattern to be processed;
and assembling the workpiece pattern to be processed and the clamp pattern together according to the first positioning surface, the second positioning surface and/or the third positioning surface.
Taking the connecting block 100 as an example, the first positioning surface is a surface formed by the first bottom surface 112 and the second bottom surface 122. The second locating surface is a second inner side surface 124 of the second edge 120. The third locating surface is a first inner side surface 114 of the first leg 110. By selecting the first to third positioning surfaces in the pattern of the workpiece to be processed, the pattern of the workpiece to be processed can be easily assembled into the pattern of the jig.
It is understood that the process of labeling the workpiece to be machined can be completed before the workpiece to be machined is assembled to the fixture or after the workpiece to be machined is assembled to the fixture. The type marking of the machining features can be completed just before clicking the control generating the machining program.
The specific steps of step S103 include, as needed:
displaying the type of the to-be-processed characteristic of the to-be-processed workpiece and processing parameter information;
modifying the type of the feature to be processed and the processing parameter information according to the operation of a user;
and generating a processing program of the workpiece to be processed according to the type of the characteristic to be processed of the workpiece to be processed and the processing parameter information.
After the type indication of all the machining features is completed, the control for generating the machining program can be clicked to automatically generate the machining program corresponding to the workpiece to be machined. Specifically, referring to FIG. 8, after clicking on the control that generates the machining program, the system pops up an auto-program verification window. The auto-program verification window will include information for hole data as well as information for face data. In one embodiment, the hole data information includes a type of hole, such as a pin hole, a through hole, a threaded hole, and the like. The hole type data is identified by the system based on previous labeling information for the hole by the programmer. The hole data information may also include hole diameter information, such as a pin hole diameter of 6mm, a through hole diameter of 9mm, and a threaded hole diameter of 6.5 mm. The diameter information of the corresponding hole can be obtained by measuring the processing characteristics in the pattern of the workpiece to be processed. The hole data information may also include hole location information. If necessary, the programmer may need to modify the hole type and hole diameter. And according to the requirement, the type and the size of the processing feature can be directly added on the interface of the automatic programming confirmation window without modifying the pattern of the workpiece to be processed. In one embodiment, the surface data information includes parameters such as the type of the surface to be processed, the cutting angle mode, the cutting direction, the rough milling allowance, the fine milling allowance and the step pitch. Specifically, in this embodiment, the type of the surface to be machined is a milling surface, the cutting angle mode is automatically set, the cutting direction is 0, the rough milling allowance is 0.1, the finish milling allowance is 0, and the step pitch is 100. Similarly, according to the requirement, the surface feature to be processed can be directly added on the interface of the automatic programming confirmation window without modifying the pattern of the workpiece to be processed.
That is, when generating the processing program of the workpiece to be processed, the type and the processing parameter of the processing feature marked with the first color and the type and the processing parameter of the processing feature marked with the second color may be displayed according to the pattern of the workpiece to be processed. At this time, if the programmer does not need to modify the type of the machining feature and the machining parameters, the next step of generating the machining program may be performed. If the programmer finds that the data of one or more items needs to be modified, the type of the corresponding processing feature or the processing parameter can be directly modified in the interface without returning to the previous step to modify the drawing. This approach can also effectively provide programming efficiency.
Referring also to fig. 9, in one embodiment, the automatic programming method further includes the following steps:
and generating a standard operation instruction of the clamp according to the clamp pattern 200 and the workpiece pattern 100 to be processed.
Specifically, the automatic programming method automatically correlates the relevant process data during the generation of the jig standard operation instruction. The automated programming method may generate the work instruction with one key unless a specific requirement is noted. In this embodiment, the generated part machining standard operation instruction may be in two file formats, PDF and excel. When the work instruction book in the PDF format is generated, the work instruction book can be directly uploaded to a server to be stored.
In the embodiment, a part machining standard operation instruction book can be generated according to the clamp pattern and the workpiece pattern to be machined. At the moment, the workpiece pattern to be processed, the clamp pattern, the type of the feature to be processed and the processing parameters are determined, so that the generated part processing standard operation instruction is accurate.
Referring to fig. 10, in one embodiment, the automatic programming method further includes the following steps:
and generating a dimension marking diagram of the workpiece to be processed according to the clamp pattern 200 and the workpiece pattern 100 to be processed.
Specifically, the maximum external dimension of the part can be marked by clicking the control part marked by the external shape, so that the clamping operation is more convenient and faster.
