The project consists of the implementation of two control devices within a work center with the aim of preventing damage to the machine and the machined piece. The devices were installed in collaboration with the company COMAU S.p.a, which develops and designs numerical control machines used mainly by companies in the automotive sector, more precisely the work was carried out on a standard SMARTDRIVECOMAU 700L (SD700L) machine. Machining centers are machines that allow various mechanical processes such as roughing, boring, milling, threading and drilling on a single piece, exploiting the possibility of automatic tool change during a work cycle. During the manufacturing processes, elements such as the spindle and tools wear out and their non-replacement could cause low quality of the finished product and in the worst case could cause damage to the machine, however it is possible to prevent these consequences by installing some devices.
