METHOD OF MONITORING THE FORMATION OF BURBS IN THE PROCESSES OF DRILLING OF PARTS.

摘要

Burr formation monitoring method in part drilling processes, based on internal signals associated with the captured torque of the spindle motor regulator to detect the formation of unwanted burrs during drilling processes. It has been shown that five characteristics of the signal are associated with the height of the burr, while being relatively insensitive to the process parameters. Experiments have been carried out on Al 7075-T6 aeronautical aluminum under high speed conditions. A threshold-based algorithm has been developed capable of distinguishing burrs outside the requirements with a reliability above 92% for the range of parameters tested. An appropriate implementation of this algorithm can be used as a system for quality control of drilling operations. Of application in aeronautics.
