In order to describe the method and system for processing the micro-texture groove with the irregular cross section in detail, the following describes an embodiment of the invention in detail with reference to the accompanying drawings.
Fig. 1 shows a flow of a method for processing a micro-texture groove with a profiled cross section according to an embodiment of the invention.
As shown in fig. 1, the method for processing a micro-texture groove with a special-shaped cross section in the embodiment of the present invention includes:
s110: determining a cutter control signal corresponding to a target running track based on a preset target running track of the cutter;
s120: controlling the cutter to vibrate based on the cutter control signal; wherein, a cutting included angle exists between the nominal cutting direction of the cutter and the vibration plane of the cutter;
s130: and finishing the processing of the micro-texture groove with the special-shaped cross section according to the vibration track and the cutting included angle of the cutter.
The process of determining the cutter control signal corresponding to the target running track based on the preset target running track of the cutter comprises the following steps: decomposing a preset cutter target running track to obtain two sub-vibration tracks in mutually orthogonal directions; respectively performing Fourier series expansion processing on the two sub-vibration tracks, and acquiring two expanded sub-vibration signals; and filtering and converting the two sub-vibration signals to obtain two control signals respectively corresponding to the two sub-vibration signals as the cutter control signals.
Furthermore, the external vibration device can be controlled to simultaneously vibrate in two directions based on the two control signals, and a cutter arranged on the external vibration device is driven to process a micro-texture groove (for short, a micro-texture groove or a micro-structure, the following same) with an abnormal section on a workpiece to be processed; wherein the nominal cutting direction of the tool has a certain cutting angle with the vibration plane of the tool.
Therefore, the nominal cutting direction of the cutter is not in the vibration plane of the cutter, the cross-sectional shape of the micro-texture groove can be changed by controlling the cutting included angle between the nominal cutting direction of the cutter and the vibration plane, and when the nominal cutting direction is vertical to the vibration plane of the cutter, the cross-sectional shape of the micro-texture groove with the special-shaped cross section is consistent with the target motion track of the cutter, and the target motion track of the cutter can be adjusted through a control signal, so that the micro-structure processing of different cross-sectional shapes is realized.
Wherein, filter and conversion treatment are carried out to two sub-vibration signals, and the process of obtaining two control signals corresponding respectively with two sub-vibration signals can further include:
firstly, carrying out high-frequency filtering processing on two sub-vibration signals to filter out high-frequency signals;
Then, the sub-vibration signal after the high-frequency filtering processing is subjected to conversion processing to obtain a control signal corresponding to the sub-vibration signal after the high-frequency filtering processing.
Specifically, after the tool target running track is decomposed, two mutually orthogonal and mutually independent sub-vibration tracks in the directions can be obtained, for example, the sub-vibration tracks respectively include one sub-vibration track located in the X-axis direction and the other sub-vibration track located in the Y-axis direction, so that fourier series expansion processing can be performed on the sub-vibration tracks in the two directions, filtering and conversion processing are performed, and then a signal after processing and filtering is converted into a control signal of an external vibration device.
The target running track of the cutter can comprise various track forms such as an elliptical track, a triangular track, a rectangular track, a trapezoidal track or other special-shaped tracks, and therefore the texture groove processing of various complex shapes of the workpiece to be processed can be achieved.
During the texture groove processing, the elliptical vibration track of the cutter can be generated by a vibration generating device (namely an external vibration device) based on a resonance or non-resonance principle, and the used vibration frequency is determined by the capacity of the vibration generating device, wherein the larger the better. The non-elliptical vibration track can be generated only by a vibration generating device based on a non-resonance principle, and when the method for processing the micro-structure groove with the special-shaped cross section is used for processing the micro-structure or the texture groove, the applicable material of the workpiece to be processed can be metal, high polymer material or other non-metal materials. The material of the used tool is usually single crystal diamond, and the cutting edge of the corresponding tool can be circular arc or linear.
Specifically, FIG. 2 shows a schematic structure of a vibration cutting parameter in a tool vibration plane according to an embodiment of the present invention; fig. 3 shows a schematic principle of machining a profiled section according to an embodiment of the present invention.
As shown in fig. 2 and 3 together, the angle 6 between the tool 1 and the horizontal plane represents the nominal tool relief angle 6, as can be seen from the cutting parameters of the side structure, the vibration trajectory 3 of the tool is trapezoidal in shape, the arrow 4 represents the conventional nominal cutting direction, i.e. the existing nominal cutting direction 4, while the direction 5 represents the (new) nominal cutting direction 5, the angle 7 represents the nominal cutting angle 7 of the tool, and the microstructure surface 9 and the texture groove depth 10 of the textured groove formed after the workpiece 2 to be machined are shown in fig. 2.
The tool clearance angle of the used tool can be determined according to the dimensional parameters of the processed texture groove, and the specific tool clearance angle should be larger than the nominal cut-in angle 7 and the lateral cut-in angle 8 of the tool.
Fig. 4 shows a schematic principle of machining a deformed variable cross section according to an embodiment of the present invention.
As shown in fig. 4, in this embodiment, the tool 1 forms a trapezoidal tool path 11 and an elliptical tool path 12 on the workpiece 2 to be processed, respectively, and the trapezoidal tool path 11 and the elliptical tool path 12 cooperate to form a deformed textured groove processing with a variable cross section.
It can be known that the new name meaning cutting direction 5 of the cutter is not in the vibration plane of the cutter, which is a significant difference from the traditional elliptical vibration cutting, the shape of the cross section of the texture groove can be changed by controlling the included angle between the new name meaning cutting direction 5 of the cutter and the vibration plane, and when the new name meaning cutting direction 5 is vertical to the vibration plane, the cross section of the processed texture groove is consistent with the vibration track of the cutter. In the cutting process, different cutter motion tracks can be obtained by changing the control signal of the cutter, and then the shapes of different sections are processed in the same texture groove.
As a specific example, the present invention is further described below by taking an implementation of an equilateral triangle vibration trajectory with a side length of 2 micrometers and a vibration period of 0.01 seconds as an example, and the following example is only used to more clearly illustrate the technical solution of the present invention, and the protection scope of the present invention is not limited thereby.
Specifically, when the target movement trajectory of the tool is a triangular trajectory, the sub-vibration trajectories in the two directions may include a triangular wave vibration signal in the X-axis direction and a trapezoidal wave vibration signal in the Y-axis direction, and a period of the trapezoidal wave vibration signal is the same as a period of the triangular wave vibration signal.
Since the function x (T) with period T can be represented as an infinite series f (x):
Figure BDA0003541275950000061
wherein, the first and the second end of the pipe are connected with each other,
Figure BDA0003541275950000071
for odd function fo(x) Can be expressed as a sinusoidal series
Figure BDA0003541275950000072
And even function fe(x) It can be expressed as a cosine series
Figure BDA0003541275950000073
Therefore, the above two directions of vibration signals can be subjected to fourier series expansion, in the practical application process, higher harmonic signals can be flexibly discarded according to the processing requirements, and the following example takes the eighth harmonic signals as the approximate values of the two directions of sub-vibration trajectory signals.
In the processing method of the special-shaped section micro-texture groove, in order to quickly obtain the harmonic signal of the sub-vibration track, the solution can be carried out through the amplitude-frequency characteristic and the phase-frequency characteristic of the harmonic signal; wherein the sub-vibration locus includes a first harmonic signal in the X-axis direction and a second harmonic signal in the Y-axis direction.
The expression formula of the first harmonic signal is:
Figure BDA0003541275950000074
the expression formula of the second harmonic signal is:

wherein f represents frequency, t represents time,

indicating the Y-axis phase.
And then two control signals required by the external vibration device can be obtained through the inverse function of the external vibration device and the target running track, and the external vibration device is driven to carry out cutting vibration of a triangular track through the control signals.

Specifically, fig. 5 shows a schematic principle of the processing of the deformed cross-section micro-textured groove according to the embodiment of the present invention.
As shown in fig. 5, a target operation track of the tool is set, which is a triangular track in this embodiment, then the target operation track is decomposed in the X-axis and Y-axis directions, a triangular sub-vibration track and a trapezoidal sub-vibration track are obtained, then fourier decomposition is performed on the two sub-vibration tracks, respectively, two target signals are obtained, where the first eighth harmonic is adopted, then synthesis verification is performed on the processed target signals, then a control signal of a signal generator is obtained according to a transfer function of an external vibration device, and based on the control signal, irregular track vibration of the tool is realized, and machining operation of an irregular cross-section texture groove of a workpiece to be machined is completed.
