The basic hypothesis of this science focuses on the study of cutting tool wear with regard to the elimination of occurrence of poor-quality holes when drilling into new austenitic ELC (Extra Low Carbon) stainless steels. The problem of drilling holes with diameter D=2 to 5mm resides in the fact that 35 to 50% of these holes do not comply with prescribed requested requirements. The cutting tools –...
Polymethyl-methacrylate (PMMA) is thermosetting plastic and called acrylic glass. PMMA sheet used in the industry to make aircraft and aquariums windows, and flat cut out letters. This research was to investigate tool wear, which was vertical milling of Polymethyl- methacrylate (PMMA). The experiment was done with HSS four flute end-milling cutter.
