A lot of it depends on how ridgid your set-up and equiptment is. Feeds and speeds mentioned above are good for top quality equiptment. If your trying those feeds and speeds on hobby level equiptment, or even a bridgeport mill, you'll burn through endmills. Feed and speed charts are for reference only and don't take into concideration how ridgid the machine or fixturing is.
1018 is nothing compared to alloys, probably one of the easiest of the carbon steel grades to cut. But a Mori CNC might cut through 1018 like aluminum would cut on a Bridgeport retro. Just something to concider. |
