What reading level is Broaching book?
To quickly assess the difficulty of the text, read a short excerpt:
Each of the rounded rings or beads on the broach is a little larger than its predecessor, thus gradually compressing the metal the desired amount. The finished hole springs back to a diameter a few thou- sandths inch less than the diameter of the largest ring on the tool, so that the size of the latter has to be determined by experiment. This allowance varies slightly also, as may be imagined, with the thickness of the wall of metal being pressed. In such a part as that shown, for instance, aft...er drawing through the sizing tool in the broaching machine, it will be found that the hole will be somewhat larger in the large diameter of the work than in the hubs. It has been found that this difference in size can be practically avoided by passing the sizing tool through the work three or four times. The operation is a rapid one as compared with reaming.
