3 Axis Motorized PIC Machine
4/20/11
Introduction
• Computer Numerical Controlled (CNC) Milling machines aresome of the most fascinating products of the manufacturingindustry.
• The 3-Axis Motorized PIC Machine is similar to the CNCMilling machine in every aspect except that it is controlled bya programmable instruction chip (PIC) instead of a userinterface.
• 3-axis motorized apparatus (using bipolar stepper motors), acontroller (using microchips and pushbuttons), and a liquidcrystal display (LCD).
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.

Stepper Motor 1
X- Axis
Controls movement of

Inputs from the
pushbuttons are sent to
the PIC16f684 and
implemented in the
stepper motors.
Receive inputs from
pushbuttons and carry
them out in the stepper
motors.
PIC16f684 Continuously run of the
desired stepper motor
until a pushbutton is
released.
LCD &
Pushbuttons Once information is
sent to the stepper
motors it will also
display stepper motor
action in the LCD

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)
