It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined arbitrarily with each other.

The wire cutting control method and the wire cutting device according to the embodiments of the present application will be described in detail below with reference to FIG. 1 , FIG. 2 , FIG. 3 , FIG. 4 , FIG. 5 , FIG. 6 and FIG. 7 . For the convenience of illustration and description, the overall composition of the wire cutting device is first introduced below. As shown in the figure, the wire cutting device may include a loading platform 100 , a cutting mechanism 300 , a column 400 , and a base 500 . Wherein, the upright column 400 is set on the first position on the base 500 , the cutting mechanism 300 is set on the upright column 400 , and the loading platform 100 is set on the second position on the base 500 .

The loading platform 100 can include a working platform 101, a Y-axis platform 102, an X-axis platform 103, a C-axis turntable 105, and a B-axis turntable, wherein the bottom of the X-axis platform 103 is arranged at the second position of the base 500, and the Y-axis platform 102 It is movably arranged on the X-axis platform 103, and the working platform 101 is movably arranged on the Y-axis platform 102. The B-axis turntable includes a fixed part 106 and a rotating part 107, and the rotating part 107 is rotatably arranged on the fixed part 106. The fixed part 106 is arranged on the working platform 101 , and the C-axis turntable 105 is arranged on the rotating part 107 , and the C-axis turntable 105 is used for carrying and clamping the material 200 to be processed. In addition, the cutting mechanism 300 has a Z-axis linkage function, that is, it can move up and down on the column 400 to realize linkage with other axes. The axial directions of the X-axis and the Y-axis are perpendicular, the Z-axis is perpendicular to the axial directions of the X-axis and the Y-axis respectively, the B-axis is parallel to the axial direction of the Y-axis, and the axial directions of the C-axis and the Z-axis are perpendicular. During the specific implementation process, a tooling 104 may be provided on the C-axis turntable 105 to facilitate the loading and clamping of the material 200 to be processed.

It is worth noting that, in order to facilitate the clear description of the embodiment, the specific directions of the X-axis, Y-axis, Z-axis, B-axis and C-axis are given in the drawings of the embodiment, but according to the design spirit of the present application, the essence is not The direction of each axis is not limited to be consistent with the embodiment, as long as the X-axis, Y-axis and Z-axis are used as translation axes, and the respective axes are perpendicular to each other, the B-axis and the C-axis are used as the rotation axes, and the B-axis and the C-axis are perpendicular to each other. Can.

During the working process, the position of the working platform 101 on the Y-axis platform 101 and the X-axis platform 103 can be adjusted, and the rotation state of the B-axis turntable and the C-axis turntable 105 can be adjusted, so that the materials to be processed on the C-axis turntable 105 200 is close to the diamond wire cutting part of the cutting mechanism 300 with a predetermined feeding route and angle, so as to realize 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 cutting mechanism under the linkage drive of the X-axis and Y-axis, and cooperate with the Z-axis movement of the cutting mechanism, and the X-axis, Y-axis, Z-axis , B-axis, and C-axis can be linked at the same time to achieve multi-axis linkage respectively. This multi-axis linkage includes at least translation in the X-axis direction, translation in the Y-axis direction and rotation around the C-axis, or at least translation around the X-axis direction , Y-axis translation, Z-axis translation, rotation around the B-axis and rotation around the C-axis, so as to achieve the movement of the planned cutting path. The processing of special-shaped curved surfaces can be realized through the path planning of the effective cutting section of the diamond wire , during the entire cutting process, the diamond wire moves on the gear train plane of the cutting mechanism to obtain a line movement relative to the workpiece (corresponding to the material to be cut 200). When the workpiece moves relative to the effective cutting section of the diamond wire, the diamond wire removes the workpiece The material thus realizes the cutting of the profiled surface with the planned path.

The wire cutting control method of the embodiment of the present application is used for the above wire cutting device with the cutting mechanism 300 and the loading platform 100. The cutting mechanism 300 and the loading platform 100 have a multi-axis linkage function. The control method includes the following steps: according to the material to be processed 200 surface processing target, determine the running trajectory of each axis; control the movement of each axis according to the running trajectory, and realize the complex surface processing of the material to be processed; among them, the X-axis and Y-axis are linked to realize the curved surface movement, and the B-axis is used to realize The shape of the space surface, the C axis is based on the B axis, which is used to realize the surface processing and keep the tangent point tracking. During the cutting process, according to the change of the curved surface of the finished product, the contact position between the material to be cut and the diamond wire cutting mechanism 300 is adjusted through the coordinated movement of the linear axis and the rotating axis of the loading platform 100 and the linear axis of the diamond wire cutting mechanism 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 this position, so as to realize the diamond wire When the direction and size of the bow are controllable, the cutting of the three-dimensional surface can be accurately completed.

Combining the foregoing and the situation of the existing technology, it can be known that the existing special-shaped surface processing adopts the CNC machine tool processing method. When processing a large surface into a small 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 this application uses a cutting mechanism 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 surface workpiece to remove excess material without removing it layer by layer. Specific tool path to obtain the desired processing surface. When diamond wire cutting is used, for more complex surfaces, the cutting mechanism makes multiple passes to process the contour and repair the curved surface. For simple curved surfaces, it can be cut and formed at one time, which significantly improves the processing Efficiency and processing quality; Compared with the flexible processing method that does not use the C-axis function, the solution of the embodiment of the application is more flexible in motion, and is especially suitable for processing two-dimensional curved surfaces of rotary bodies. Specifically, although X/Y linkage can The profile of the semicircle on both sides of the cutter head is processed, but because the cutter head cannot pass through the supporting tooling under the workpiece, the cylindrical profile cannot be closed. However, after adding the C-axis, when the X-axis and Y-axis are linked to the set position and cut into the After the workpiece is finished, the machining of the cylindrical surface can be realized directly through the C-axis rotary motion, the machining surface is closed and the machining accuracy can be improved. In addition, the rotation of the C-axis is realized by moving on the rotation axis of the B-axis. The B-axis can swing 0-90° in both positive and negative directions, and the C-axis can rotate 0-360° around its own axis, and can realize positive and negative rotation. Continuous rotation in two directions; in order to avoid the 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 tooling device are placed on the C axis of the rotary table. It is set coaxially with the C-axis of the tooling and worktable, so as to ensure that the workpiece rotates coaxially when the C-axis rotates, thereby realizing the linkage between the rotary axis and the linear axis. In addition, the solutions of the embodiments of the present application effectively expand the applicable scenarios of diamond wire cutting.

It should be noted that, in the foregoing embodiments, the cutting mechanism 300 and the loading platform 100 have a multi-axis linkage function means that both the cutting mechanism 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 freedom according to the needs of processing, so as to complete the predetermined processing trajectory as a whole. It can be seen from the foregoing embodiments that in the multi-axis linkage function, for example, when the XYZBC five-axis linkage function is provided, the cutting mechanism 300 has the Z-axis function, and the loading platform has the XYBC-axis function; but in other embodiments, it is not limited Here, it is also possible that the cutting mechanism 300 has multiple axis functions, and the loading platform has one or the remaining types of axis functions.

After adopting the scheme of the embodiment of the present application, when cutting, according to the curve change of the shape surface, the cutting tool or the material to be cut will be automatically shifted to adjust the walking angle, so that the direction of each cutting point where the diamond wire travels is consistent with the shape of the position. The surface tangent direction is kept consistent, so as to maintain a fixed cutting wire bow and realize the 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 numerical control program, and the movement curve is formed by the two linkages to realize the surface cutting. When the traditional cutting method performs two-axis linkage cutting, the diamond wire is resisted by the material to be cut, and a wire bow will be generated along the tangent direction of the curve of the cutting point. Because the cutting tool does not move, the center line of the cutting wheel groove will produce a deviation angle with 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 accordingly, making the size and direction of the deviation angle not fixed, resulting in inaccurate cutting trajectory . However, the solution of the embodiment of the present application addresses the above-mentioned problems by adding 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. When cutting, the material to be cut will automatically adjust the walking angle according to the curve change of the shape surface, so that the direction of each cutting point where the diamond wire travels is consistent with the tangent direction of the shape surface at this position, so as to maintain a fixed cutting wire bow , realize the controllable direction and size of the wire bow, avoid the problem that the theoretical cutting graph does not match the actual cutting graph due to the diamond wire wire bow, and realize high-precision surface cutting of the diamond wire.

In 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 slideway can be set on the top of the X-axis platform 103, and a first slide block can be set at the bottom of the Y-axis platform 102 accordingly part, the first slider part is slidingly matched with the first slideway; in addition, a second slideway can be set on the top of the Y-axis platform 102, and a second slider part can be set on the bottom of the working platform 101, and the second slider part Sliding fit with the second slideway. In order to realize the adjustment and control of the X-axis and Y-axis movements and the rotation control of the C-axis platform, the loading platform can also include an X-axis drive mechanism arranged between the X-axis platform 103 and the Y-axis platform 102, and an X-axis drive mechanism arranged between the Y-axis platform 103 and the Y-axis platform 102. The Y-axis driving mechanism between the axis platform 103 and the working platform 101, the B-axis turning mechanism arranged between the working platform and the B-axis turntable, and the B-axis turning mechanism arranged between the working platform 101 and the C-axis turntable 105 The C-axis rotary mechanism and the axial drive mechanism can be realized by means of screw nuts, and the B-axis rotary mechanism and the 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 realized by controlling the states of the X-axis driving mechanism, the Y-axis driving mechanism, the B-axis turning mechanism and the C-axis turning 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 mechanism 300 has a Z-axis linkage function. Specifically, a Z-axis chute 401 can be provided on the column 400, and the cutting mechanism 300 ( The mounting frame 301) is slidably matched with the Z-axis chute 401 through the slide plate 302 (in other embodiments, it can also be a combination of a slide block and a guide rail), and a lifting adjustment mechanism is also provided between the column 400 and the slide plate 302 (not shown in the figure). shown) to realize the Z-axis axial lifting of the cutting mechanism 300 on the column 400 . The lifting adjustment mechanism can drive the high-precision ball screw through the servo motor, and cooperate with the high-precision linear guide rail to make the cutting mechanism move precisely in the Z-axis direction. After adopting this scheme, the adjustment of the cutting mechanism 300 along the Z direction can be realized through the movement of the Z axis, without the need for supporting various tools, and the processing height can be adjusted flexibly to match the processing position to the maximum extent, and reduce the influence of the wire bow on the processing accuracy. to the minimum.

After the cutting mechanism has the Z-axis function, in the online cutting control method, the Z-axis can be used to adjust the tangent point of the workpiece to be located 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 machining in five-axis space. The five axes are X axis, Y axis, Z axis, B axis, and C axis. Axis rotation. Taking the circular wire as an example, the CNC system is used to realize the NC-based circular diamond wire cutting trajectory planning and the CAM-based processing path programming. Horizontal X-axis, Y-axis orthogonal sliding table, two-axis linkage can realize curved surface movement, on this basis, add two directions of rotation, namely B, C 2 axes, C axis is based on A axis, A The shaft opening swings to realize the space curved surface shape, and the C-axis rotates and can be rotated 360° reciprocatingly or superimposedly, which is used to realize curved surface processing and ensure tangent point tracking, and is equipped with the Z-axis for cutter head feed 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 the CAM processing path programming cooperate with linkage to realize complex surface processing.

In addition, when the traditional cutting method performs two-axis linkage cutting, the diamond wire is subjected to the resistance of the material to be cut, and a wire bow will be generated along the tangent direction of the curve of the cutting point. When the diamond wire is subjected to lateral force, it is easy to jump out of the wheel groove during the movement, and the wire jumping phenomenon occurs. Even if the wire is not skipped, when the force direction of the diamond wire changes in the opposite direction, the wire will curl up, causing abnormal cracks on the cutting surface. marks, affecting the quality of the cut surface. During the cutting process, the diamond wire and the workpiece are always in a very unstable positional relationship, which causes problems such as wire jumping and poor surface quality during the cutting process. Therefore, a better method is to let the cutter head always swing along the feed direction. Make the diamond wire always press the cutting direction to cut, 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 to cut. In this state, the holding force of the wheel groove on the wire is the best, which improves the processing accuracy and quality, and the five-axis space multi-axis linkage can Do three-dimensional special-shaped complex surface processing, such as two-dimensional curve, surface processing, three-dimensional cylinder, cone and other shape processing.

In addition, in the specific implementation process, the cutting mechanism 300 can adopt different cutter head schemes. As an example, as shown in the figure, the cutting mechanism 300 can include an installation frame 301, a first cutting wheel 303, a second cutting wheel 304, a tension Wheel 305, driving wheel 306, diamond wire (not shown). Wherein, the first cutting wheel 303, the second cutting wheel 304, the tension wheel 305, and the driving wheel 306 are sequentially arranged on the installation frame 301 at intervals, and the diamond wires successively go around the edges of each wheel to form ring wires respectively, and the installation frame 301 passes through the slide plate. 302 is set on the column 400 . During use, the driving wheel 306 is used to provide power to the cutting wire net, and drives the diamond wire to move so as 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 length of the cutting wire, and the tension wheel 305 is used to provide protection for the tension of the wire mesh and maintain a stable cutting tension.

In addition, during specific implementation, under the control of the computer numerical control (CNC) system, the coordinate movement can be processed at the same time. The tool axis vector of the entire cutting trajectory process displayed by multi-axis linkage can be changed according to the needs, 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 the space surface processing is realized. For horizontal X-axis, Y-axis orthogonal sliding table and B-axis, C-axis turntable, four-axis linkage can realize curved surface movement. For the solution with Z axis, it is equipped with cutter head feeding Z axis to adjust the tangent point of the workpiece If it is located at the midpoint of the effective cutting line segment, it can realize five-axis linkage processing with a better wire cutting position.
