Capstone phase 2 Online Overview: 3-Axis Motorized PIC Machine

  1. 1. 3 Axis Motorized PIC Machine<br />Lead Engineer: Briana McCall<br />Support Engineers : Raymond Bryant & Roger Smith<br />Advisor: Dr. Chan<br />4/20/11<br />
  2. 2. Introduction<br /><ul><li>Computer Numerical Controlled (CNC) Milling machines are some of the most fascinating products of the manufacturing industry.
  3. 3. 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.
  4. 4. 3-axis motorized apparatus (using bipolar stepper motors), a controller (using microchips and pushbuttons), and a liquid crystal display (LCD). </li></li></ul><li>Abstract Highlights<br />Similar to a computer numerical controlled (CNC) machine <br />Controlled by a programmable instruction chip (PIC)<br />The main goal of this project is to build the motorized stages and control them by using a microchip 16f684. <br />
