Retrofitting of milling machine by using stepper motor / Jereni Diong

The operation of machining of conventional mining machine is proposed to be retrofitted by constructing the controller of X-Y table milling machine based on a new concept of computer control system. There are three slide motions of conventional miffing machine which are operated manually by action of operators. Each of the slide motion has their handwheels rotation to move the sfide movements. Such muling machine's operations are slow and production rates are not productive. Hence, the replacement of handwheel by the drive motor such as a stepper motor will improve the speed, accuracy and efficiency of production. The concepts of computer numerical controlled system is applied in the process of retrofitting the conventional milling machine. The hardware of stepper motor's controller and serial/parallel interface are implemented as controller unit to control the stepper motor and software programming is used to monitor the operation of the X-Y table milling machine.
