CNC
Computer numerical control technology, which controls machine tool motion through digital instructions. It is widely used in precision manufacturing and can drive tool paths for machining directly from digital models.
Timeline (last 90 days)
The original author treats CNC as a tool that extends the hands rather than a machine that replaces them, holding that tools change the boundaries of efficiency while the criteria for judging craftsmanship are still set by people.
Comments on HN present two positions: one holds that CNC liberates Gothic stone carving from the monopoly of a small number of craftsmen and lowers the threshold for reproducing historical components; the other worries that when curves can be automatically generated by software, the spatial intuition behind traditional setting-out methods will gradually be lost.
A reader in the HN comment section pointed out that what CNC can solve is the problem of "form," while "texture" (such as the layering of chisel marks and the subtle undulations of edges) still depends on the stonemason's hand feel.
CNC generates toolpaths directly from digital models, bypassing the traditional setting-out step.
The brittleness of stone means that too deep a cut during rough machining can cause chipping or propagate internal cracks, while too fast a feed during finishing can cause surface spalling, so the parameter window for stone CNC is much narrower than for metal and requires operators to experiment repeatedly according to the specific type of stone.
Most open-source robotic arm or CNC projects remain at millimeter-level precision, and open-source practice at the sub-micrometer level is relatively scarce.
Robot integrators do not produce the robot bodies themselves, but are responsible for designing fixtures, connecting communications with PLCs and CNCs, building safety circuits, and completing on-site debugging and after-sales service.
CNC milling is subtractive manufacturing (cutting away excess material from a solid block), while 3D printing is additive manufacturing (depositing material layer by layer).
CloudNC's core mission is to automate CNC (computer numerical control) machining programming, replacing the manually experience-dependent programming process with algorithmic automation.
CNC (Computer Numerical Control) controls the movement trajectory, speed, and cutting depth of machine tools through pre-programmed computer instructions, achieving machining precision at the micrometer level.
