Abstract
The contact angle of ball and screw affects the ballscrew's life. A novel method for measurement of the contact angle of ballscrew is developed by using the photoelastic effect and digital image processing techniques. Substituting the steel ball by a photoelastic disk, the contact angles of the disk at contact with a 90° groove and a real screw are measured by processing the digitized photoelastic disk images. Acceptable results have been achieved for consideration of the accuracy and reliability of the measurement. The method is cost-effective and is able to substitute the commonly used profiler for practical inspection of the screw.
