3 Ways to Solve Uneven CNC Stone Carving
3 Ways to Solve Uneven CNC Stone Carving
Many users must have had such problem in real CNC stone carving. The performance after cnc stone carving is so different! Some places are less than set depth, some just reach, or some with deeper thickness.
This problem is relatively normal. Because hard materials, such like gravestone, granite and marble, especially tombstone in large area, must has error. It is impossible to be very smooth or flat on the top and bottom. That is to say, if put stone materials on the cnc worktable, some places are higher than other places.
How to solve uneven cnc stone carving? It needs skill and experience.
1. Table top cnc milling by one stone carving tools.
It can smooth stone surface, and save worry while cnc stone carving.
2. To different surface roughness, we can divide and save engraving path into upper, middle and lower parts.
(1) In actual cnc stone carving, determine tool path origin in the left bottom of materials; then reset X axis and Y axis in workpiece coordinate.
(2) To z axis, the diamond bits setting depends on the loaded tool path.
If machining the top part first, we need to move straight flute bit to the center section of the top part, and then confirm z axis.
(3) The sane principle applies to remaining two parts.
(4) So the thickness of cnc stone carving will be more average, with much better performance.
3. Another method is to measure four corners of materials, seeing which position is high or low. Then cushion something under the materials properly, keeping as level as possible.
From this we can conclude that, cnc stone carving needs human wisdom to make up its shortcomings.
