What reading level is Machine Tool Drives book?
To quickly assess the difficulty of the text, read a short excerpt:
As most machines requiring the kind of drive with which we are here con- cerned have spindles which either revolve the work, or a cutting tool that has to be worked at certain predetermined speeds dependent on the peripheral speed of the work or cutter, a natural question to be asked at this point is, "What is the law governing the progression of these speeds?" As an example to show what relation these speeds must bear to one another, let us suppose that we have five pieces of work to turn in a... lathe, their diameters being 1, 2, 5, 10, and 20 inches respectively. In order that the surface speed may be the same in each case we must revolve the one-inch piece twice as fast as the two-inch piece, because the circumference varies directly as the diameter, so that a two-inch piece would be twice as great in circumference as the one-inch piece. The five-inch piece would revolve only one-fifth as fast as the one-inch piece; the 10-inch piece l/10th, the 20-inch piece l/20th. We have seen that the addition of one inch to the diameter of the one-inch piece reduces the speed 100 per cent.
