Repeat steps S6-S9 three times to perform groove processing on the four fillets on the workpiece.

[0005] Furthermore, in step S2 and step S9, when the workpiece is removed, a high-pressure hair dryer is required to clean the workpiece.

[0006] Furthermore, in step S3, when setting up the processing platform, the rotation center of the processing platform is aligned with the rotation center of the rotating surface of the machine tool.

[0007] Furthermore, in step S3, the processing platform is composed of two base platforms, and the two base platforms are perpendicular to each other, and the two base platforms are parallel to two adjacent straight edges on the workpiece.

[0008] Furthermore, in step S4, when setting the positioning template, it is necessary to first locate the position of the pressure plate in the template to ensure that the pressure plate can be pressed on the straight edge of the workpiece.

[0009] Furthermore, in step S5, the arc mold includes an inner circular ring and an outer circular arc plate, the radius of the inner circular ring is consistent with the radius of the fillet on the workpiece, the inner side surface of the outer circular arc plate is fitted with the outer side surface of the inner circular ring, the inner circular ring and the outer circular arc plate are both provided with adjustment grooves, the inner circular ring and the outer circular arc plate are connected by bolts, and the bolts connecting the inner circular ring and the outer circular arc plate pass through the adjustment grooves.

[0010] Furthermore, in step S5, when installing the arc master, the center of the arc master needs to be aligned with the rotation center of the processing platform.

[0011] Furthermore, in step S6, before placing the workpiece on the processing platform, the outer arc plate needs to be pulled upward so that the top of the outer arc plate is higher than the inner circular ring.

[0012] Furthermore, in step S7, when the workpiece is pressed by the positioning template, the pressing plate in the positioning template needs to be pressed on the straight edge of the workpiece as much as possible.

[0013] Furthermore, in step S8, before the rounded corners are processed on the workpiece, the outer arc plate needs to be pulled downward so that the outer arc plate is lower than the inner circular ring.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. By using a planer to process the straight edge groove of the workpiece and a floor-standing boring and milling machine to process the rounded corner groove of the workpiece, the purpose of not using a CNC machining center and reducing the processing period is achieved. By manufacturing the corresponding arc template according to the size and shape of the rounded corner of the workpiece, it can ensure that the rounded corner of the workpiece is supported when the floor-standing boring and milling machine is performing groove processing; 2. Use the inner circular ring in the arc mold to support the rounded corners of the workpiece, and use the outer arc plate in the arc mold to position the workpiece when placing it. Use an outer arc plate that can be adjusted up and down so that when processing the rounded corners and grooves, the outer arc plate can be moved down and staggered with the processing tool to avoid the outer arc plate interfering with the processing tool.

Conventional straight edge processing grooves can be processed using a planer, which is fast and accurate enough; S2, removing the workpiece 1 processed in step S1, and then using a ruler to check the straight edge bevel on the workpiece 1 to ensure that the straight edge bevel is a 20° bevel; S3. Set up a processing platform on the rotating surface of the floor-standing boring and milling machine. When setting up the processing platform, align the rotation center of the processing platform with the rotation center of the rotating surface of the machine tool to ensure that the processing platform can be driven to rotate coaxially when the rotating surface of the floor-standing boring and milling machine rotates. The processing platform is composed of two base platforms 2, and the two base platforms 2 are vertical. The two base platforms 2 are parallel to two adjacent straight edges on the workpiece 1. The base platform 2 is set to support the workpiece 1. At the same time, the two vertical base platforms 2 can support the two adjacent straight edges of the processing fillet; S4. Set the positioning templates on both sides of the processing platform. When setting the positioning template, it is necessary to first locate the position of the pressure plate in the template to ensure that the pressure plate can press on the straight edge of the workpiece 1, because the straight edge of the workpiece 1 is narrow, especially after the groove processing, the space that can be pressed by the pressure plate is narrow; S5, manufacture the arc mold 3, install the arc mold 3 on the processing platform, the arc mold 3 includes an inner circular ring 301 and an outer circular arc plate 302, the radius of the inner circular ring 301 is consistent with the radius of the fillet on the workpiece 1, the inner side surface of the outer circular arc plate 302 is in contact with the outer side surface of the inner circular ring 301, the inner circular ring 301 and the outer circular arc plate 302 are both provided with an adjustment groove 303, the inner circular ring 301 and the outer circular arc plate 302 are connected by bolts, and the inner circular ring 301 and the outer circular arc plate 302 are connected. The bolt passes through the adjusting groove 303, and the inner ring 301 is provided to support the rounded corner of the workpiece 1 to prevent the rounded corner from being deformed by force during groove processing.

The adjusting groove 303 is provided to adjust the upper and lower positions of the outer arc plate 302; when installing the arc backing 3, it is necessary to align the center of the arc backing 3 with the rotation center of the processing platform, so that the arc backing 3 and the processing platform rotate coaxially when the processing platform rotates; S6. Place the workpiece 1 on the processing platform. Before placing the workpiece 1 on the processing platform, the outer arc plate 302 needs to be pulled upward so that the top of the outer arc plate 302 is higher than the inner ring 301.
