Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The tool parameter adjustment method based on the numerical control machine tool of the present invention is described below with reference to fig. 1. The tool parameter adjustment method based on the numerical control machine tool can be applied to electronic equipment, and the electronic equipment can be intelligent product terminals such as computers and intelligent televisions. When the method is specifically applied, the method for adjusting the cutter parameters based on the numerical control machine tool comprises the following steps:
step S100, determining surface information of a target part based on a three-dimensional model of the target part, wherein the surface information comprises surface shape information and surface size information.
In this embodiment, before a numerical control machine tool is used to process a part, a three-dimensional model of a target part is first obtained, and the target part is a part that needs to be processed finally. The three-dimensional model is the three-dimensional visual model of the target part, and the shape of the target part is reflected in the three-dimensional model, so that the embodiment can determine the surface size information and the surface shape information according to the three-dimensional model.
Specifically, in this embodiment, the CAD drawing of the target part is first obtained, and then the CAD drawing is input into preset software, so that the three-dimensional model can be generated according to the CAD drawing. Then, the embodiment performs grid division on the three-dimensional model to obtain a plurality of grid blocks. And then, respectively extracting edge information of each grid block, and splicing and measuring all the extracted edge information to obtain the surface information of the target part. According to the embodiment, the three-dimensional model is subjected to grid division, and the edge information of a plurality of blocks obtained through division is extracted, so that the surface shape information and the surface size information of the target part can be obtained more accurately. Of course, in other implementations, after the three-dimensional model is generated, the surface shape information and the surface size information of the target part may be identified based on the visual image identification method, which may be implemented by those skilled in the art in a suitable manner, and this is not a limitation.
Step S200, determining a machining step corresponding to the target part and a machining allowance corresponding to each machining step based on the surface shape information and the surface size information.
After the surface shape information of the target part is obtained, the embodiment can determine which surfaces need to be processed and which processing steps need to be performed when the part to be processed is processed to the target part according to the surface shape information and the surface size information, and can determine all processing steps corresponding to the target part and determine corresponding processing allowance according to each processing step. In the present embodiment, the machining allowance reflects a difference in size between the target part and the part after the completion of the machining step at this time. According to the embodiment, through the surface shape information and the surface size information, the whole processing process of the target part can be subjected to system analysis, so that the processing allowance can be accurately determined, and the cutter parameters can be accurately adjusted in subsequent steps.
Specifically, the embodiment first determines a surface to be processed corresponding to the part to be processed based on the surface shape information. The surface to be processed reflects all surfaces to be processed in the part to be processed. Then, based on the surfaces to be processed and the surface size information corresponding to each surface to be processed, a processing step, that is, a processing mode to be processed is determined. Since each machining step details the tool, the jig, and the corresponding model data used in the machining process, the present embodiment can determine the tool model corresponding to each machining step. Next, the present embodiment obtains the number of times of feeding corresponding to each of the machining steps, where the number of times of feeding may be determined according to the amount of cutting required for the surface to be machined, and when the number of times of feeding is determined, the present embodiment may determine the machining allowance corresponding to each of the machining steps according to the tool model and the number of times of feeding. Since the cutting angle, the cutting speed and the cutting amount may be different for each tool model, the present embodiment can quickly determine the cutting amount when cutting with the number of times of cutting by using the tool corresponding to the tool model according to the number of times of cutting and the tool model. Specifically, the embodiment may determine, based on the tool model, a machining volume of a tool corresponding to the tool model when the tool is fed each time, where the machining volume is used to reflect a cutting amount of the tool when the tool is fed each time for the part to be machined. And then determining the machining allowance corresponding to each machining step according to the machining volume and the number of times of feeding.
And step S300, acquiring the motion parameters of a machining shaft in the numerical control machine tool, and determining the machining error of the numerical control machine tool based on the motion parameters.
Because the digit control machine tool is when processing, and the processing axle is continuous motion to the processing axle itself can produce certain vibrations in the course of working, and this vibrations can influence the processing route, and then influence processingquality, produces the machining error. In order to accurately analyze the machining error, so as to adjust the cutter parameters according to the machining error in time in the subsequent steps, the embodiment obtains the motion parameters of the machining shaft by analyzing the machining shaft of the numerical control machine tool, and then determines the machining error of the numerical control machine tool according to the motion parameters.
Specifically, the present embodiment first obtains the state information of the machining shaft in the numerical control machine tool, where the state information may be used to reflect whether the machining shaft is in a moving state at this time, and if the machining shaft is in a moving state, it may be determined that the state information of the machining shaft at this time is a machining state. And when the state information is a processing state, acquiring the motion parameters of the processing shaft, wherein the motion parameters comprise a rotation speed and a feeding speed. In this embodiment, the machining shaft includes a rotation shaft and a linear shaft, the rotation shaft and the linear shaft have different movement modes, the rotation shaft moves on a vertical plane, and the linear shaft moves on a horizontal plane. Next, in this embodiment, preset tool path information is obtained, the tool path information reflects a feed path, and thus, a position to be processed is determined.
In a specific application, the present embodiment may first determine the actual cutting amount of the machined surface based on the motion parameter and the tool path information. Since the motion parameters include the rotation speed and the feed speed, the actual cutting amount of the tool when the tool is processed at the rotation speed and the feed speed can be determined based on the tool path information, and then, the embodiment can compare the actual cutting amount with the target cutting amount of the processing step recorded in the processing technology file of the target part, so as to obtain the processing error.
In addition, the present embodiment may be based on analyzing the roughness of the machined surface, where the roughness may be used to reflect the machining quality of the machined surface, and if the roughness is low, it indicates that the machining quality is good, that is, that the machining error is small. In another implementation manner, the method can also be implemented by analyzing the intermediate form between the part to be processed and the target part when analyzing the processing error. Because each processing step is completed, the part to be processed presents an intermediate form, a certain gap exists between the intermediate form and the target part in terms of shape and size, the embodiment can identify the size of the intermediate form by adopting the image identification technology after the processing step is completed, and then the dimension is compared with the target cutting amount of the processing step recorded in the processing technology file, so that the processing error can be obtained.
And step 400, adjusting tool parameters according to the machining allowance and the machining error, and machining the part to be machined by using the adjusted tool parameters, wherein the tool parameters comprise tool coordinates and tool postures.
When the machining allowance and the machining error are obtained, the present embodiment can adjust the tool parameters based on the machining allowance and the machining error. The tool parameters of the embodiment comprise the tool coordinates and the tool posture, so that the tool coordinates and the tool posture are adjusted, the tool can better process the part to be processed, and the processing quality is improved.
Specifically, the present embodiment trains in advance a reinforcement learning model that is a model obtained by performing reinforcement training in advance based on a machining allowance data sample and a machining error data sample and corresponding tool parameter samples. In this embodiment, a correspondence relationship among the machining allowance data sample, the tool parameter sample and the machining error data sample may be pre-established, and model training may be performed based on the correspondence relationship to obtain the reinforcement learning model, where the reinforcement learning model uses the machining error data sample as a constraint condition, and the tool parameter sample corresponding to the machining allowance data sample is automatically output. Therefore, when the machining allowance and the machining error are input into the reinforcement learning model, the reinforcement learning model takes the minimum machining error as a constraint condition, and then corresponding tool parameters are automatically output according to the machining allowance. Therefore, the processing allowance and the processing error can be analyzed, and the tool coordinates and the tool posture can be adjusted according to the processing allowance and the processing error, so that the processing path can be adjusted in time, the processing quality is improved, the situation that reworking is needed due to too large error is avoided, and the processing efficiency is improved.
