Web based shape inspection system for the forging products having complicated shapes

The outer race of the constant velocity(CV) joint is an important load-supporting automotive part, which transmits torque between the transmission and the wheel. The outer race is difficult to be forged, because its shape is very complex and the required dimensional tolerances are very stringent. Therefore, the internet based shape inspection system is developed in this study to provide quick and accurate measuring data. Proposed system uses mechanical displacement sensors to measure the shape of CV joint that has six inner ball grooves, and commercially available LabView program is used to process measured data into the dimensional shape. Developed program provides a simple user interface that enables users to have real-time access of data measured from industrial production lines. Furthermore, the measured data can be exchanged via the internet between users and forging system operators. A java applet helped the system connection via internet. A data, IP access, is transmitted to the packet by TCP/IP. Our proposed system has many advantages over current measuring systems including fast and efficient data processing by real-time measuring, and system flexibility.
