To determine the knife point, you need to consider the following factors:
< br >
1. Engraving design: First of all, you need to determine the design pattern to be carved, including shape, size, details, etc., which will affect the choice and positioning of the knife point.
< br >
2. Material selection: Different materials need to use different knife points, such as wood, stone, metal, etc., have their own suitable knife point types.
< br >
3. Tool selection: Choose the right cutter or milling cutter according to the design pattern and material, and the shape and size of different tools will also affect the selection of knife points.
< br >
4. Knife point density: The knife point density refers to the spacing between the nicks left by the tool, the higher the density, the more delicate the engraving line, but it will also increase the processing time and difficulty.
< br >
5. Depth of the knife point: the depth of the knife point determines the effect of engraving, such as shallow engraving, medium engraving or deep depth can be selected.
< br >
6. Processing order: For complex design patterns, it may be necessary to carve different parts separately, and a reasonable processing order needs to be developed to ensure the best engraving effect.

According to the above factors, the test and adjustment can be carried out according to the actual situation, and the best knife point can be gradually determined. At the same time, you can also refer to professional processing experience and technical literature, and learn from the experience and methods of others.
