Abstract
Measurement, monitoring and control are very important in precision machining technology. In order to increase the accuracy of the measurement system; application of camera or vision is very essential. Automatic control is also vital for the measurement performance to be improved. During measurement of the gear profile; human monitoring sometimes may face danger as the stylus is very small and thin as well as the probe moves with a maximum speed of 10mm/s. At this speed if accident happen to the machine then there is high possibility to break the stylus tips and scatter everywhere and its even danger to human eyes. Thus, human monitoring is necessary during measurement for checking the performance of the system. This paper presents the successful implementation of the vision system in precision engineering which saves time and increases safety of the measurement system.
