noun

1. The amount of work that can be done by one machine in one hour; a billable hour for one machine. (Said of, for example, a piece of heavy equipment or a machine tool.)

   • With the right carbide tooling and toolpath programming, you're not looking at too many machine-hours for a job like this. If you're going to putz around with cheaper tooling and guesstimated feedrates, then you'll pay for those in more machine-hours.
