[0025] As a preferred technical solution of the present invention, the target material is a copper target material.
[0026] As a preferred technical solution of the present invention, the cutter head is made of diamond.
[0027] In a second aspect, the present invention provides a method for integrally forming the R angle and the outer peripheral surface of a target material, wherein the R angle and the outer peripheral surface of the target material are processed and integrally formed using the processing tool described in the first aspect, and the processing method comprises:
[0028] The axis of the machining tool is parallel to the target material's surface to be machined. The machining tool rotates and translates close to the target material's surface to be machined. The main tool head machines the target material's outer peripheral surface, and the R-angle machining teeth machines the target material's R angle. The outer peripheral surface and R angle of the target material are machined in one go.
[0029] As a preferred technical solution of the present invention, the rotation speed of the machining tool is 5000-6000r / min, for example, it can be 5000r / min, 5100r / min, 5200r / min, 5300r / min, 5400r / min, 5500r / min, 5600r / min, 5700r / min, 5800r / min, 5900r / min or 6000r / min, but is not limited to the listed values, and other unlisted values within the numerical range are also applicable, preferably 5500r / min.
[0030] When the tool speed is less than 5000r / min, chip accumulation is likely to occur, resulting in increased surface roughness. When the tool speed is greater than 6000mm / min, tool wear will be aggravated. Tool wear will cause the tool edge radius to become larger, thereby increasing the roughness of the blade surface, causing the plastic deformation of the workpiece surface to increase, causing the existing residual area to be squeezed or the grooves to deepen, forming burrs.
[0031] Preferably, the feed rate of the machining tool is 2500-3000 mm / min, for example, it can be 2500 mm / min, 2550 mm / min, 2600 mm / min, 2650 mm / min, 2700 mm / min, 2750 mm / min, 2800 mm / min, 2850 mm / min, 2900 mm / min, 2950 mm / min or 3000 mm / min, but is not limited to the listed values, and other unlisted values within the numerical range are also applicable. It is further preferably 2800 mm / min.
[0032] The feed rate directly affects the surface stress of the target material, which in turn affects the flatness of the target material. When the feed rate is less than 2500mm / min, the residual stress of the target material processing surface is compressive stress, and the flatness of the target material surface cannot be guaranteed. Reducing the feed rate can reduce the residual area height, thereby reducing the surface roughness, but when the feed rate is reduced to less than 2500mm / min, the roughness will increase instead; when the feed rate is greater than 3000mm / min, the milling force increases with the increase of the axial feed rate, and the plastic deformation area of the target material surface also increases. The cutting temperature of the target material surface increases, which will increase the residual tensile stress caused by thermoplastic deformation, thereby affecting the flatness of the target material. If the feed rate is too large, the cutting thickness will also increase, and the influence of factors such as cutting force and cutting vibration on the roughness will also increase, resulting in a significant increase in surface roughness.
[0033] Compared with the prior art, the present invention has the following beneficial effects:
[0034] The present invention designs a processing tool with an R corner and an outer peripheral surface integrally formed specifically for target material processing. The R corner and the outer peripheral surface of the target material can be processed simultaneously with one tool, thus avoiding tool change during the processing, shortening the processing time, improving the processing efficiency, and preventing tool connection marks from appearing at the joint between the R corner and the outer peripheral surface caused by tool change. At the same time, the flatness of the side of the target material is controlled by adjusting the tool parameters and the tool, thereby improving the product yield and ensuring that the target material surface can be used for normal sputtering.

[0091] Comparative Example 1
[0092] This comparative example provides a method for processing the R angle and the outer peripheral surface of a target material, and the processing method comprises:
[0093] The outer peripheral surface and R corner of the target material are processed separately, and the feed rate and tool speed are kept exactly the same as those in Example 3 during the processing.
[0094] Obvious tool marks appeared at the joint between the R corner and the outer peripheral surface of the target material 4 processed by the above processing method. The surface roughness Ra of the processed surface was 0.13 μm, and the flatness tolerance was 2.3 mm.
[0095] By comparing the surface roughness data and flatness tolerance data of Example 6, Example 7 and Example 3, it is found that the surface roughness and flatness tolerance of Example 6 and Example 7 are greater than that of Example 3. It can be seen that when the feed rate is less than 2500mm / min, the residual stress of the target material processing surface is compressive stress, and the flatness of the target material surface cannot be guaranteed. Reducing the feed rate can reduce the residual area height, thereby reducing the surface roughness, but when the feed rate is reduced to less than 2500mm / min, the roughness will increase instead; when the feed rate is greater than 3000mm / min, the milling increases with the increase of the axial feed rate, the cutting force increases accordingly, the plastic deformation area of the target material surface also increases accordingly, and the cutting temperature of the target material surface increases, which will increase the residual tensile stress caused by thermoplastic deformation, thereby affecting the flatness of the target material. If the feed rate is too large, the cutting thickness will also increase accordingly, and the influence of factors such as cutting force and cutting vibration on the roughness will also increase, resulting in a significant increase in surface roughness.
[0096] By comparing the surface roughness data and flatness tolerance data of Example 8, Example 9 and Example 3, it is found that the surface roughness and flatness tolerance of Example 8 and Example 9 are greater than those of Example 3. It can be seen that when the tool speed is less than 5000r / min, chip accumulation is likely to occur, resulting in increased surface roughness. When the tool speed is greater than 6000mm / min, tool wear will be aggravated. Tool wear will cause the tool edge radius to become larger, thereby increasing the roughness of the blade surface, causing increased plastic deformation of the workpiece surface, causing the existing residual area to be squeezed or the grooves to deepen, forming burrs.
[0097] By comparing the surface roughness data and flatness tolerance data of Comparative Example 1 and Example 3, it is found that the surface roughness and flatness tolerance of Comparative Example 1 are significantly greater than those of Example 3. This is because two processes are used to respectively form the R angle and the outer peripheral surface of the target material. When the tool is changed, tool marks will be generated at the joint, and burrs will be generated at the joint, resulting in the surface roughness and flatness failing to meet the design requirements.
