- 1) The path spacing in the engraving tool path plays a vital role in the quality of wood CNC Machining.
- 2) When non-mahogany solid wood is used for carving parts, the smaller the hardness or density, the worse the processing quality; the rougher the texture, the worse the processing quality. According to the material type and material properties, reducing the path spacing and feed speed as appropriate can improve the processing quality.
- 3) The engraving time is very important for actual production. When the production plan is urgent, in order to shorten the production time, you can increase the path spacing and increase the feed rate as appropriate, but the premise is that you must fully consider the material properties of the wood being processed: for the hardness and For Wood Chess Pieces with lower density, just increase the feed rate; for wood with greater hardness and density, it is necessary to consider increasing the path spacing and feed rate to obtain the best quality effect (increased path spacing and feed rate The value of the magnification should be within the allowable range to ensure processing quality and safe production).
- 4) For woods with relatively small density and hardness, such as fir and tomentose poplar, the carving quality is relatively rough and is not suitable for use as fine carvings for furniture. Although ash has a relatively high hardness and density, it has too many conduits, resulting in a rough texture and relatively poor carving effect. Therefore, it is not recommended to use ash as furniture carving parts. Ash wood has a finer texture than ash wood and can be used as carved furniture parts.
Among the three factors that affect the quality of wood carving, the path spacing has the greatest impact, the feed rate has a smaller impact, and the moisture content of the wood has no significant impact.
Therefore, the path spacing a plays a crucial role in the quality of engraving. As shown in the figure, the smaller a is, the more times the tool cuts back and forth on the same width of wood, and the finer the quality of the engraving, which is the so-called fine carving. . The feed magnification is adjusted on the established path spacing, and there will be no reversible change in the engraving quality. The smaller the feed magnification, the slower the processing speed, that is, the slower the tool cutting speed, the finer the engraving quality. When the feed magnification is larger and the one-time engraving and milling amount is larger, although the wood dice machining efficiency can be improved, the processed surface will be rough. Therefore, in actual production, it is not only necessary to consider the relationship between path spacing and engraving quality, but also the impact of feed rate on production efficiency.
