  • How to Determine Cutting Speeds for Machining Tools

    If that hunk of rubber rolls one-quarter mile in 60 seconds, its equivalent “cutting speed” would be 1,320 feet per minute (equal to 15 mph), which is a fairly normal clip if this were a carbide tool machining aluminum. Now imagine your car’s axle is a machining center spindle, with a Michelin-sized end mill mounted to the tire.
