It depends on what you mean by floor. The floor at one’s home is made of a variety of things: tiles, concrete, granite, marble, limestone, wood, cork etc. Most of these can actually be milled to create beautiful pieces of artwork. Some of them can also be milled to make useful things.
Take linoleum, for instance. It is made from substances. These generally include solidified linseed oil, solid pine resin, ground cork, finely pulverized wood, and limestone, usually on a canvas backing. An excellent use of these is to make stamps.
I simply created an SVG file, imported it in Autodesk Fusion 360, and made a CAM gcode file for the OtherMill.
Well, milling is fun. However, milling linoleum is a special case. The dust created from the milling is very much like powder. So it is very difficult to clean the OtherMill after the milling process is complete. This is also the first time I used more than one bit to mill the material, as some of the parts needed a finer milling tool.
Of course, this stamp is for display purpose only. The actual stamps will always be mirrored so that the text can be read once a paper is stamped.
