The aim of this study is to convert a conventional lathe to numerical
control by using a computer based motion control unit. Main theme of
this is to obtain the movement of stepper motor system with lead
screw, which is moved by given commands through the computer in
certain limits. To obtain this action the movement of machine tools
is taken as the model. The shaft with lead screw is beared at two
ends by ball bearing. To drive the system, two stepper motors are
used. Four-axis stepper motor driver used to drive the motors by
sending pulses is fed with a transformer. Stepper motors have been
controlled from PC parallel port by a software program, written in
Turbo Pascal. It is not used any interface control card between
motors driver and computer. It reduced the cost of the system.
