Background technique

Conventional diamond linear surface cutting uses the linkage of the X-axis and Y-axis to perform curve feed to achieve CNC surface cutting. This method has certain flaws. Relative to the material, the cutting tool always maintains the same direction and position. When the material being cut is fed in a curve, it will produce resistance to the diamond wire along the tangent direction of the cutting point on the curve, causing the diamond wire to move in that direction. Produces a line bow. This line bow will form a certain angle with the centerline of the wheel groove of the cutting guide wheel (Figure 1). The tangent directions at each point of the curve are not the same, which causes the direction of the line bow generated during cutting to always change. The constant changes in the direction of the wire bow cause the diamond wire to swing and oscillate, resulting in oscillatory changes in the cutting resistance. These changes cause the direction and size of the wire bow to be uncontrollable, eventually causing the actual cutting position to deviate from the preset walking trajectory, resulting in a decrease in cutting accuracy. The vibration during the cutting process can also cause problems such as disconnection and disconnection, and the failure rate is high.

Among them, the input cutting program of step b in the above specific working process may include the following steps: obtaining the preset path to be cut and the preset line bow value. The preset path to be cut can be obtained by inputting the cutting trajectory image in the image interface of the control system. , or directly input coordinates, etc. in the control system. At the same time, the preset line bow value can be set according to the preset path to be cut. For example, different preset paths to be cut can all be set with a unified preset line bow value, or different preset line bow values. It is assumed that the paths to be cut are respectively set to different preset line bow values. It can be set according to actual needs and is within the protection scope of this application. The preset paths to be cut include curved paths, which can be entirely composed of curved paths, or composed of curved paths and straight paths, which can be set as needed.

According to the preset path to be cut, the tangent angle of the cutting point and the distance between the cutting point and the preset rotation axis are respectively obtained, and the rotation angle of the preset rotation axis corresponding to the cutting point in the preset path to be cut is calculated; where, the preset rotation The axis can be arranged on the cutting assembly or the material carrying assembly, and the preset rotation axis is determined according to the setting position of the rotation drive device. According to the tangent angle of the cutting point and the distance between the cutting point and the rotation axis, the rotation angle of the preset rotation axis is calculated to control the rotation of the preset rotation axis according to the different traveling positions during the traveling process, so that the actual cutting direction of the cutting point is consistent with It is preset that the tangent directions at the cutting points in the path to be cut are consistent.

The B-axis turntable includes a fixed part 106 and a rotating part 107. The rotating part 107 is disposed on the fixed part to be able to rotate around the B-axis direction. 106, the fixed part 106 is disposed on the working platform 101 and then on the Y-axis platform 102, where the B-axis direction is parallel to the Y-axis direction; the C-axis turntable 105 is disposed on the rotating part 107 so as to be rotatable around the C-axis direction. The C-axis turntable 105 is used to carry and clamp the material 200 to be processed, and the C-axis direction is perpendicular to the B-axis direction. During the specific implementation process, a tooling 104 can be provided on the C-axis turntable 105 to facilitate the loading and clamping of the material 200 to be processed.

During the working process, the position of the working platform 101 on the Y-axis platform 102 and the X-axis platform 103 can be adjusted, and the rotational status of the B-axis turntable and the C-axis turntable 105 can be adjusted, thereby making the material to be processed on the C-axis turntable 105 200 approaches the diamond wire cutting part of the cutting assembly 300 with a predetermined feed route and angle, thereby realizing the processing of the heterogeneous curved surface of the material 200 to be processed. During specific implementation, the workpiece (corresponding to the material 200 to be cut) can move relative to the diamond wire of the cutter head under the linkage drive of the X-axis and Y-axis.

Specifically, although X/ Y linkage can process semicircular profiles on both sides of the tool head. However, since the tool head cannot pass under the workpiece to support the tooling, the cylindrical profile cannot be closed. However, after the C axis is added, when the X and Y axes are linked to the set After positioning and cutting into the workpiece, the cylindrical surface can be processed directly through the C-axis rotation movement. The processing profile is closed and improved processing accuracy can be obtained. In addition, the C-axis rotation is realized by moving on the B-axis rotation axis.

During the entire cutting process, the diamond wire moves on the wheel train plane of the cutting assembly to obtain the line movement relative to the workpiece (corresponding to the material to be cut 200). When the workpiece is effectively cut relative to the diamond wire, When moving, the diamond wire removes the workpiece material to achieve cutting of special-shaped surfaces in a planned path.

Combining the above and the existing technology, it can be seen that in the existing technical solution, the special-shaped curved surface is processed by CNC machine tools. When processing a larger surface into a small surface, the workpiece needs to be removed layer by layer, which results in low processing efficiency and relatively low processing efficiency. Compared with traditional CNC machine tool processing, the solution of the embodiment of the present application uses a cutting component with a diamond wire as a cutting tool, which can perform interpolation motion through two-axis linkage, and use the diamond wire to cut the curved workpiece to remove excess material without removing it layer by layer.

For simple curved surfaces, it can be cut and formed in one go. The processing efficiency and processing quality are significantly improved. In addition, the solution of the embodiment of the present application effectively expands the applicable scenarios of diamond wire cutting.

During the specific implementation process, in order to better realize the motion performance of the X-axis platform 103 and the Y-axis platform 102, a first slide can be set at the top of the X-axis platform 103, and correspondingly a first slide block can be set at the bottom of the Y-axis platform 102. part, the first slider part is in sliding fit with the first slideway; in addition, a second slideway can be set at the top of the Y-axis platform 102, and a second slider part can be set at the bottom of the working platform 101.

In specific implementation, the lifting mechanism can be in the form of a telescopic mechanism such as an oil cylinder, or a sliding fit of a slide block. Moreover, the lifting mechanism can independently drive the working platform to lift, or can drive the X-axis platform and Y-axis platform as a whole. and working platform to realize the lifting and lowering of the working platform. This enables the following The movement of the cutting assembly along the Z-axis has a similar effect, so that when the cutting assembly does not have the Z-axis movement function or it is inconvenient to control the Z-axis movement, the C-axis lifting and lowering of the loading platform can achieve the corresponding effect.

On this basis, in order to further improve the processing performance and flexibility of the wire cutting device, the cutting assembly 300 can have a Z-axis movement function.

The tension wheel 305 is used to tension the wire network and maintain stable cutting tension.

In addition, during specific implementation, machining can be performed simultaneously with coordinated movements under the control of a computer numerical control (CNC) system. The multi-axis linkage display of the tool axis vector of the entire cutting trajectory process can be changed as needed, and is controlled by the X, Y, and Z trajectory control axes. The C-axis is realized, and then the material is removed layer by layer, and finally spatial surface processing is realized.

The control method includes the following steps: According to the material to be processed The curved surface processing target of 200 determines the linked running trajectory of each axis; controls the motion of each axis according to the running trajectory to realize complex curved surface processing of the material to be processed; among them, the X-axis and Y-axis are linked to realize curved surface motion, and the B-axis is used to realize Space surface shape, the C axis is based on the B axis, used to achieve surface processing and maintain tangent point tracking. During the cutting process, according to the change of the curved surface of the finished product to be obtained, the contact position between the material to be cut and the diamond wire cutting assembly 300 is adjusted through the coordinated movement of the linear axis and the rotating axis of the material loading platform 100 and the linear axis of the diamond wire cutting assembly 300 , contact angle, feed position, feed angle, feed stroke and other parameters, so that the walking direction of each contact cutting point between the material to be cut and the diamond wire is always consistent with the tangent direction of the surface at that position, thereby achieving the goal of cutting on the diamond wire line. With the direction and size of the bow controllable, the cutting of three-dimensional curved surfaces can be accurately completed.

Combining the above and existing technology, it can be seen that the existing special-shaped curved surface processing uses CNC machine tool processing. When processing a larger surface into a smaller surface, the workpiece needs to be removed layer by layer, and the processing efficiency is low. Compared with For traditional CNC machine tool processing, the solution of the embodiment of the present application uses a cutting component with a diamond wire as a cutting tool, which can perform interpolation motion through two-axis linkage, and use the diamond wire to cut the curved workpiece to remove excess material without removing it layer by layer. Finally, using The desired processing surface can be obtained through a specific cutting path. When diamond wire cutting is used, for more complex surfaces, the cutting component must pass multiple times to perform contour processing and repair the curved surface. For simple curved surfaces, it can be cut and formed in one go, which significantly improves processing. Efficiency and processing quality; compared with flexible processing methods that do not use the C-axis function, the solution of the embodiment of the present application is more flexible in movement, and is especially suitable for processing two-dimensional curved surfaces such as rotary bodies. Specifically, although X/Y linkage can Semi-circular profiles on both sides of the cutter head are processed. However, since the cutter head cannot pass under the workpiece to support the tooling, the cylindrical profile cannot be closed. However, after the C-axis is added, when the X-axis and Y-axis are linked to the set position and cut in After the workpiece is moved, the cylindrical surface can be processed directly through the C-axis rotary motion. The processed surface is closed and improved processing accuracy can be obtained. In addition, the C-axis rotation is realized by moving on the B-axis rotation axis. The B-axis can swing in both positive and negative directions in the range of 0-90°, and the C-axis can rotate around its own axis in the range of 0-360°, and can achieve both positive and negative directions. Continuous rotation in one direction; in order to avoid interference between the diamond wire and the rotary table during processing, a tooling 104 can be set above the rotary table, the workpiece is placed above the tooling, and the workpiece and the workpiece are installed on the C-axis of the rotary table, and the workpiece It is coaxially arranged with the C-axis of the tooling and workbench, which ensures that the workpiece rotates coaxially when the C-axis rotates, thereby achieving linkage between the rotary axis and the linear axis. In addition, the solution of the embodiment of the present application effectively expands the applicable scenarios of diamond wire cutting.

It should be noted that in the aforementioned embodiments, the cutting assembly 300 and the loading platform 100 have a multi-axis linkage function means that the cutting assembly 300 and the loading platform 100 have a multi-axis linkage function as a whole, that is, during the processing It has multi-axis axial movement freedom, and can implement different axial movement freedoms according to processing needs, thereby completing the predetermined processing trajectory as a whole. As can be seen from the foregoing embodiments, in the multi-axis linkage function, for example, when it has the XYZBC five-axis linkage function, the cutting assembly 300 has the Z-axis function, and the material loading platform has the XYBC axis function; however, it is not limited in other embodiments. Here, the cutting assembly 300 may also have multiple axis functions, and the loading platform may have one or the remaining types of axis functions.

After adopting the solution of the embodiment of the present application, during cutting, according to the curve change of the shape surface, the cutting tool or the material to be cut will automatically index and adjust the walking angle, so that the direction of each cutting point of the diamond wire is consistent with the position. The surface tangent direction remains consistent, thereby maintaining a fixed cutting wire bow and achieving controllable direction and size of the wire bow. When processing according to the traditional cutting method, the diamond wire cutting tool does not move, and the material to be cut moves along the X-axis and Y-axis through the control of the CNC program. The two linkages form a motion curve to achieve shape cutting. When the traditional cutting method performs two-axis linkage cutting, the diamond wire is subject to the resistance of the material being cut, and will produce a wire bow along the tangent direction of the curve of the cutting point. Since the cutting tool does not move, the center line of the cutting wheel groove will deviate from the bending direction of the wire bow. As the shape of the curve changes, the resistance and direction of the diamond wire will change, and the bending direction and size of the wire bow will also change, making the size and direction of the deviation angle unfixed, resulting in inaccurate cutting trajectories. . In order to solve the above problems, the solution of the embodiment of the present application adds a rotation axis in addition to the X-axis and Y-axis, and realizes high-precision surface cutting of the diamond wire through the rotation of the material to be cut. During cutting, the material to be cut will automatically shift and adjust the walking angle according to the curve change of the shape surface, so that the direction of each cutting point of the diamond wire walking is consistent with the tangent direction of the shape surface at that position, thereby maintaining a fixed cutting line bow. , realize the controllable direction and size of the wire bow, avoid the problem of inconsistency between the theoretical cutting pattern and the actual cutting pattern caused by the diamond wire bow, and achieve high-precision shape cutting of diamond wire.

During the specific implementation process, in order to better realize the motion performance of the X-axis platform 103 and the Y-axis platform 102, a first slide can be set at the top of the X-axis platform 103, and correspondingly a first slide block can be set at the bottom of the Y-axis platform 102. part, the first slider part is in sliding fit with the first slideway; in addition, a second slideway can be set at the top of the Y-axis platform 102, and a second slider part can be set at the bottom of the working platform 101. The second slider part Slide with the second slide. In order to realize the adjustment control of the X-axis and Y-axis movements and the rotation control of the C-axis platform, the loading platform may also include an X-axis drive mechanism arranged between the X-axis platform 103 and the Y-axis platform 102, The Y-axis driving mechanism between the axis platform 102 and the work platform 101, the B-axis rotation mechanism provided between the work platform and the B-axis turntable, and the Y-axis drive mechanism provided between the work platform 101 and the C-axis turntable 105 The C-axis rotary mechanism and the axial drive mechanism can be realized by nut screws, and the B-axis rotary mechanism and C-axis rotary mechanism can be realized by motor drive. In the cutting control method, controlling the movement of the X-axis, Y-axis, B-axis, and C-axis is achieved by controlling the states of the X-axis drive mechanism, the Y-axis drive mechanism, the B-axis rotation mechanism, and the C-axis rotation mechanism respectively.

On this basis, in order to further improve the processing performance and flexibility of the wire cutting device, it is preferable that the cutting assembly 300 has a Z-axis linkage function. Specifically, a Z-axis chute 401 can be provided on the column 400, and the cutting assembly 300 (of The mounting frame 301) is slidably matched with the Z-axis chute 401 through the sliding plate 302 (in other embodiments, it can also be a combination of a sliding block and a guide rail). A lifting adjustment mechanism is also provided between the column 400 and the sliding plate 302 (not shown in the figure). shown) to realize the Z-axis axial lifting of the cutting assembly 300 on the column 400. The lifting adjustment mechanism can drive a high-precision ball screw through a servo motor and cooperate with a high-precision linear guide to make the cutting assembly move accurately in the Z-axis direction. After adopting this solution, the cutting assembly 300 can be adjusted along the Z direction through Z-axis motion without the need for multiple tooling. The processing height can be flexibly adjusted to maximize the matching of the processing position and reduce the impact of the wire bow on the processing accuracy. to the lowest.

After the cutting component has the Z-axis function, in the line cutting control method, the Z-axis can be used to adjust the workpiece tangent point to be at the midpoint of the effective cutting line segment, and the movement of the Z-axis can be controlled by controlling the state of the lifting adjustment mechanism. That is to say, the control method of the embodiment of the present application can realize multi-axis linkage processing in five-axis space. The five axes are X-axis, Y-axis, Z-axis, B-axis, and C-axis. B-axis: rotates around the Y-axis direction, and C-axis: rotates around the Z-axis. axis rotation. Taking the ring wire as an example, the CNC system is used to realize NC-based circular diamond wire cutting trajectory planning and CAM-based processing path programming. Horizontal X-axis and Y-axis orthogonal slide table, the linkage of the two axes can realize curved surface motion. On this basis, two directions of rotation are added, namely B and C axes. The C axis is based on the B axis, B The axis opening swing is used to realize the spatial curved surface shape. The C-axis rotates and can reciprocate or superimpose 360° rotation, which is used to realize curved surface processing and ensure tangent point tracking. It is also equipped with the Z-axis of the cutter head to adjust the tangent point of the workpiece. Located at the midpoint of the effective cutting line segment, the five-axis NC-based circular diamond wire cutting trajectory planning and CAM processing path programming work together to achieve complex surface processing.

In addition, when the traditional cutting method performs two-axis linkage cutting, the diamond wire is subject to the resistance of the material being cut, and will produce a line bow along the tangent direction of the curve of the cutting point. When processing curved surfaces, when the Y-axis is used laterally in conjunction with the X-axis When the diamond wire is in motion, it is easy to jump out of the wheel groove due to lateral force, resulting in a jumper phenomenon. Even if the wire jumper is not performed, when the direction of the force on the diamond wire changes in the reverse direction, the wire will curl up, causing abnormal irregularities on the cutting surface. marks, affecting the quality of the cutting surface. During the cutting process, the diamond wire and the workpiece are always in a very unstable positional relationship, causing problems such as wire skipping and poor surface quality during the cutting process. Therefore, a better way is to always swing the tool head along the feed direction. The diamond wire is always pressed against the cutting direction for cutting, that is, the tangent point tracking method. The solution of the embodiment of the present application can make the diamond wire always press the cutting direction for cutting. In this state, the wheel groove has the best grip on the wire, which improves the processing accuracy and quality. Moreover, it adopts five-axis spatial multi-axis linkage to achieve Perform three-dimensional special-shaped complex surface processing, such as two-dimensional curve and surface processing, three-dimensional cylinder, cone and other shape processing.

In addition, during specific implementation, the cutting assembly 300 can adopt different cutter head solutions. As an example, as shown in the figure, the cutting assembly 300 can include a mounting frame 301, a first cutting wheel 303, a second cutting wheel 304, a tension Wheel 305, driving wheel 306, diamond wire (not shown). Among them, the first cutting wheel 303, the second cutting wheel 304, the tension wheel 305, and the driving wheel 306 are arranged on the mounting frame 301 at intervals in sequence. The diamond wires pass around the edges of each wheel in order to form annular wires. The mounting frame 301 passes through the sliding plate. 302 is arranged on the column 400. During use, the driving wheel 306 is used to provide power to the cutting wire network and drive the movement of the diamond wire to provide cutting force for cutting. The first cutting wheel 303 and the second cutting wheel 304 are respectively used to support the diamond wire along the feeding direction. When cutting the workpiece, the segment of the diamond wire between the two cutting wheels is the effective cutting line length, and the tension wheel 305 is used to tighten the wire network and maintain stable cutting tension.

In addition, during specific implementation, machining can be performed simultaneously with coordinated movements under the control of a computer numerical control (CNC) system. The multi-axis linkage display of the tool axis vector of the entire cutting trajectory process can be changed as needed, and is controlled by the X, Y, and Z trajectory control axes. The B-axis and C-axis are realized, and then the material is removed layer by layer, and finally spatial surface processing is realized. For horizontal X-axis, Y-axis orthogonal slide tables and B-axis and C-axis turntables, four-axis linkage can realize curved surface motion. For solutions with Z-axis, it is equipped with a tool head to feed the Z-axis to adjust the workpiece tangent point. Located at the midpoint of the effective cutting line segment, five-axis linkage processing with a better line cutting position can be achieved.
