Introduction : 

Introduction Computer Numerical Controlled (CNC) Milling machines are some of the most fascinating products of the manufacturing industry. The 3-Axis Motorized PIC Machine is similar to the CNC Milling machine in every aspect except that it is controlled by a programmable instruction chip (PIC) instead of a user interface. 3-axis motorized apparatus (using bipolar stepper motors), a controller (using microchips and pushbuttons), and a liquid crystal display (LCD).

Abstract Highlights : 

Abstract Highlights Similar to a computer numerical controlled (CNC) machine Controlled by a programmable instruction chip (PIC) The main goal of this project is to build the motorized stages and control them by using a microchip 16f684.

Slide 8: 

How Will It Work ? 3-Axis Motorized PIC Machine Main components 3 stepper motors, Dremel, LCD, 4 microchips (PIC16f684) Dremel motor tool does the cutting LCD & pushbuttons control parameters of the stepper motor 4 Microchips (16f684) control the entire operation, such as receiving inputs from the LCD and translating it to the stepper motors. From a top isometric prospective 2 motors will control the stage (up & down, and left & right), The other control the motor tool (in & out)
