Abstract
A conventional single spindle automatic screw machine, which includes a number of conventional operating machine mechanisms to perform the machine functions, is retrofitted with air cylinder/air solenoid combinations actuatable by electrical signals to control the operational sequence of the machine mechanisms, replacing the existing mechanical system of trip drums and trip dogs which perform that function. Also, the driving means which control the movement of the turret and the cross slides, and hence, the machine tool, relative to the work piece, is disconnected from the machine motor and made independently controllable by the addition of servo or stepping motors which are actuatable by external electrical signals. The electrical signals for control of the added motors and the air cylinder/air solenoid combinations are provided by a numerical control apparatus.
