These parts are then placed in the re-cesses in the rim of the chuck, where they are secured with setscrews. The machining is done in two operations, the cutterseach being revolved through an angle of 90 deg. in the recesses,after the first operation is completed. The chuck has a capacityof twenty-four cutters. The Selection of Machine Tools Each Tool Must Be Studied Critically and Scien-tifically in Order to Secure Greatest Efficiency BY GEORGE \V. ARMSTRONG The output of a shop and the economy effected in its opera-tion depend primarily on the capacity of its machine tools. Co-ordinately the capacity hinges o
