1. The lower tool point refers to the position where the tool contacts the surface of the workpiece during the machining of the fine carving surface. 2. The definition of the lower cutting point is to determine the starting position of the cutting tool on the workpiece, usually select a specific point or a specific position on the workpiece surface as the lower cutting point.
The reason for selecting the lower tool point is to ensure the accuracy and stability of the cutting process, to avoid collision between the tool and the workpiece or error during the cutting process. 3. In the machining of fine carved surface, the selection of the lower cutting point needs to consider the shape of the workpiece, the cutting path, the size of the tool and other factors.
Accurate positioning of the lower tool point improves machining accuracy and efficiency, while also reducing vibration and tool wear during cutting.
Therefore, the definition and selection of the lower cutting point in the machining of fine carved surface is very important.
