In this video, I demonstrate how to conserve a worn 6mm endmill while machining 1/4" steel on my PrintNC CNC machine. I use the endmill at 10k rpm and 700mm/min to make full depth passes. The settings I use are a single flute with 0.1mm WOC (width of cut) at full DOC (depth of cut). Watch as I carefully remove excess material without taking off too much, ensuring that the endmill lasts for all four plates. #PrintNC #CNC #steel #machining #endmill #conservation #manufacturing #engineering #technology #machinist
