Woodworking engraving machines often use 3D engraving when processing reliefs, so that the effect is more artistic and has a strong 3D three-dimensional sense. The realization of this function is mainly through the design of the tool path and the selection of tools. . When designing the tool path, choose to automatically generate an engraving program with varying depths and use a sharp knife to complete it. However, sometimes the area between the two lines of the pattern is relatively large or the area with thicker strokes cannot be processed, and the so-called engraving will occur. "Island", which requires an appropriate increase in the overlap rate when making paths.
Woodworking engraving machine engraving software mainly has two processing methods for "island" processing: island processing and continuous engraving.
The so-called island processing is to process some unprocessed areas mentioned above by bottom milling. When clearing and bottom milling, its "overlap percentage" should be defined.
The continuous engraving method refers to the area that is milled as a plane as the initial plane, and continues to perform three-dimensional processing. In this way, the actual engraved depth may be greater than the designed depth, but it cannot exceed the height of the blade plus the handle. During processing, you can properly modify the pick-up distance. The pick-up distance is a three-dimensional corner-clearing processing parameter. When processing larger objects or using thicker tools, the pick angle distance can be increased accordingly. Normally, the default value of 0.1 mm is recommended. If the distance of the pick angle is too small, the number of pick angles may be too much, which will affect the actual processing effect of the woodworking engraving machine.
Whether the woodworking engraving machine performs 3D engraving or other engraving techniques, the engraving machine operator needs to be proficient in the process of use, and master as many relevant engraving processing skills as possible in order to better play the performance of the woodworking engraving machine.
