The author explores a method to reduce noise and vibrations generated by home CNC machines, specifically the 3018 model. The primary issue identified is the high-pitched screeching sound produced by cutting tools during the processing of rigid materials, such as metal or printed circuit boards.
While standard industrial practices involve using coolant to lubricate tools and remove debris, the author proposes submerging the workpiece entirely under a thick layer of liquid. This approach aims to dampen the acoustic vibrations that occur during the milling process.
To test this hypothesis, the author utilized a full-metal 3018 series CNC machine. The experiment involved performing the milling process while the material was covered by a layer of water or gel-like liquid soap to evaluate its effectiveness in noise reduction.
