Techniques for Layered Engraving on Stone Carving Machines

Stone carvings typically feature significant relief, making flat carvings appear more like three-dimensional sculptures. This necessitates a considerable depth of carving, but the maximum cutting depth of carving machine tools is limited. Moreover, the depth of carving determined by the stone material cannot be too great, as it may damage the tools and equipment. Therefore, layered carving techniques must be employed.

Typically, we generate models from images, open the carving pattern, and set the relief dimensions and depth. The depth refers to the total depth of the relief. After setting up, we preview the relief effect with a 3D render. Next, we generate the tool paths. Select "Process Relief," first choose the tool, and pay close attention to the "Cutting Stepover" parameter in the tool editing settings. This value determines the spacing between each cut layer, which can be adjusted based on the material hardness and the quality of the tool. Below the tool selection, there's an option for "Multi-Z Axis Layer Cutting"; remember to check the checkbox when layering. In the Z-axis height of the *th path, input the negative value for the depth you want to carve. For the subsequent path, input the total relief depth, also a negative value. The remaining settings are the same as for non-layered carvings.

After all settings are complete, you can simulate the tool path to see that the generated path is calculated in layers. Import the path into the stone carving machine control system to proceed.
