Productivity analysis of machining milled surfaces

Abstract

Milling is a widely applied procedure because its kinematic versions and applied tools allow the machining of several surfaces and surface combinations. In this study the efficiency of material removal performed by face milling was analyzed when machining aluminum alloys by diamond tools. The analyzed material is the material of an automotive industrial component that is produced in large scale. When producing components in large scale the analysis of material removal efficiency and profitability of machining is particularly important. The efficiency of material removal has a direct impact on the time parameters characterizing the production. The focus of the paper is how the productivity can be increased by the selection of technological data that reduce the machining time of the procedure or increase the values of material removal rate or surface rate. Experiments and analyses were carried out for machining prismatic components among operating conditions. It is found that in a given workpiece-gadget-machine-tool system, a significant reduction in production time and therefore cost savings can be reached by appropriately chosen cutting data while the geometric accuracy and surface quality of the component remain as specified in the part drawing.
