A study on roughness of the micro-end-milled surface produced by a miniatured machine tool

In this paper, the influence of micro-end-milling cutting conditions on roughness of a surface-machined using a miniaturized machine tool is presented. The cutting parameters considered are spindle speed, feed rate, depth of cut and tool diameter. Experiments are design to determine which parameters are most influential on surface roughness. Statistical methods are used for finding out the optimal values of milling parameters. The influence of each milling parameter in micro-end-milling process is analyzed and the magnitude of parameters is determined. The interaction effect of parameters to surface roughness is discussed and the mathematical model for micro-end-milling is established.
