(Copy of certificate included in the Appendix).3. ConclusionA tool wear measurement system using machine vision has beensuccessfully developed in this research. Automatic software correction of toolmisalignment allows the system to be used in-cycle in the workshop environment.Measurement can be carried out without removal of the cutting tool from themachine. The system can also be used to measure workpiece roughness withoutcontact with the workpiece.7
