Abstract
This paper discusses the cutting force and the cutting area during the cutter rotation in milling of glass. It is shown that no brittle fracture occurs on the machined surface in the picture took on a SIM (Scanning Ion Microscope). Three components of the cutting force in machining of glass, then, are measured with a set of piezo dynamometers. The noise signals induced by the vibration of the fixture, the tool, the spindle and the table are removed with the filters in the frequency domain. The cutting forces measured show that the cutting processes in machining of glass are the same manner as that of machining of metals; and the cutting force also increases with the feed rate. The cutting area with the cuter rotation is analyzed to show the effect of the tilt of the tool on the machined surface and tool life in glass machining. The glass can be machined at a high cutting speed by the tilt of the milling, tool. The tilt of the tool leads to a long tool life with air cutting time.
