| Abstract: | ABSTRACTThis research focuses on the cutting performance of Al2O3 and Si3N4 ceramic cutting tools in up-milling plywood, the results of which are as follows. First, whether the tool material is Al2O3 or Si3N4 ceramic, the cutting forces at low-speed cutting were less than those at high-speed cutting, and the machining quality at low-speed cutting was greater than that at high-speed cutting. Then, whether at low- or high-speed cutting, the cutting forces of Al2O3 cutting tools were higher than those of Si3N4 cutting tools, and the machining quality of plywood milled by Al2O3 ceramic cutting tools was poorer than that milled by Si3N4 ceramic cutting tools. Finally, Si3N4 ceramic cutting tools were more suitable to machine the wooden productions with much glue content than Al2O3 ceramic cutting tools for the better machined quality. |
