【Abstract】 Machined Surface morphology of particle-reinforced metal matrix composites is analyzed in this paper. Effects of Cutting parameters and micro-construction of composites on machined surface roughness are investigated. A carbide tool with guiding and finishing land was designed by analyzing the forming mechanism of machined surface and status of tool wear. Experimental results show that roughness of machined surface is reduced and tool life improved significantly by using this new type tool.更多还原
