If cuts are of long duration cutting speed can readily be deter-mined by experiment, but this is not practical in the run of machine-shop work. The determination of cutting speed for miscellaneouswork is a difficult matter, and must be given special study in eachcase, ever} means toward uniformity of product being resorted to. The drive is but a detail of the machine. We should aim at aharmonious whole, not combining an efficient drive with an out-of-date tool. The motor-driven tool of the future should not be con-sidered a combination, but a unit suited for certain specific motor-drive problem is essentially a matter for the machinebuilder to settle, and when a machine is purchased the customershould have the assurance that the drive has been given the samecare in design and construction as any other part of the machine,and need not be considered as a distinct issue.
