Clock Face "Gorgeous Gorges" cnc

thingiverse

On a CNC machine, it's relatively common to use a V-bit to create intricate carvings. Unlike a standard end mill, a V-bit can produce lines of varying widths if the bit cuts at different depths. The clock face was made using a V-bit, but without employing v-carving techniques. A very thin font yields a dramatic effect when a large V-bit engraves its outlines. This effect is further enhanced by the dark layers of glue that are a distinctive feature of plywood. The overlap of the numbers can be adjusted by controlling the overall depth. When milling this design, it's crucial to be aware that the depth per cut must not be uniform, but rather increasing, with the first cuts cutting quite deep (like 4 mm), while the last cut should only be 0.2 mm. As the diameter increases with the cutting depth, more material becomes engaged. If this engagement is too much, it may result in lost steps, burnt edges, or even a broken bit. I created the clock on my Sorotec Basicline CNC machine using a 24 mm diameter V-bit and a 4 mm single flute end mill for the recess of the clockwork and the main circle.
