M4 - Vertical Sliding System for COMET Optical Scanning


Project No.: M4

Project Title: Vertical Sliding System for COMET Optical Scanning


1. INTRODUCTION

In the process of Reverse Engineering (RE), the scanning systems usually are fixed in position or only have a very limited working range. In some RE cases, dealing with the complexity of intricate 3D parts requires to have additional working range.

To achieve high quality results and specially tailor to different RE needs, it often requires unique sets of slide rail to accommodate its application such as digitizing of a giant architecture.

To facilitate the process, this project aims to design and fabricate a sliding rail system for the RE scanning

2. TECHNICAL OUTLINE

In this project, the students are required to develop a vertical sliding system for our COMET optical digitizing system.

The basic concept of is to have a unit for accommodate our optical digitizing system, sliding it along vertical direction with simple linear transmission mechanism and lock it in a position and identify its location with reference.

A system in many aspects is simple and effective way to make the scanning system travel along Z-axis and should consist of the following:-

a. The base of system should be rigid and stable,
b. A proper holding unit for housing our COMET optical head and allows it working properly,
c. The device contains functions for leveling adjustment and fixed onto the work bench or machine,
d. A locking device should be applied for securing the scanner holding unit in a position,
e. The transmission mechanism for travel along is linear, which is manual control,
f. A distance measure meter should be equipped as to determine the position of the scanner unit with a fix reference.

4. REQUIREMENTS

Students are required to:

  • Design and manufacture the Vertical Sliding System based on the given outline and specifications;
  • Schedule the manufacturing process;
  • Prepare a bill of materials and a budget estimation for the whole project;
  • Conduct commission testing;

Upon the completion of the MU project, a group presentation and a group report are also required.
