A concave arc can be achieved by using a tool to adjust the path of the tool.
First, the shape and size of the tool need to be determined, and then the tool is tangent to the workpiece surface, cutting and trimming along the desired arc several times until the desired accuracy and shape are achieved. In addition, it is also necessary to pay attention to maintaining the appropriate tilt Angle, rotation direction, feed depth and other factors to ensure the quality and efficiency of the processing effect. For different materials and processing requirements, precision carving can also use other processing methods, such as using different shapes and sizes of tools, adjusting processing parameters, changing the position and Angle of the workpiece and other means to meet the requirements of precision carving.
Therefore, in practical applications, it is necessary to select the appropriate engraving method according to the characteristics and actual needs of the processing object, and carry out technical adjustment and optimization to obtain the best processing effect.
Fine carving concave curved surfaces requires the use of some special tools and skills.
First, you need to use 3D modeling software to make the model. Next, it can be processed using a CNC machine or a laser engraving machine. During processing, a spherical grinding head or drill can be used to cut and gradually carve out the arc. In addition, you can also use hand tools for fine trimming and polishing, making the arc more smooth and fine. It should be noted that the concave arc processing requires a certain amount of experience and skills, and it is necessary to carefully consider each step of the operation to avoid errors and burrs.
1. First of all, according to the design drawing or model, determine the position and shape of the groove that needs to be carved.

2. Then use CAD software and other tools to draw the surface model of the groove and convert it into STL file format.

3. Use CAM software to import STL files and make tool path planning. When planning the path, it is necessary to consider the diameter, speed, feed speed and other parameters of the tool, as well as the collision between the tool and the workpiece, cutting force and other factors.

4. According to the path planning result, install the tool on the engraving machine and process. In the processing process, it is necessary to pay attention to the relative position of the workpiece and the tool, the cutting depth of the tool, the cutting speed and other factors to ensure the engraving effect and processing quality.

5. After the processing is completed, follow-up processes such as surface treatment and polishing are carried out to improve the quality and beauty of the engraving.
