Cutter runout will redistribute the instantaneous uncut chip thickness and the cutting forces in multi-fluted milling process. In this paper, a new procedure is proposed to identify the cutter runout parameters for flat end milling process. By combining least-square method, mathematical derivations and implementation procedures are carried out based on the relative deviation between each cutting edge and the spindle rotation center, measured by a dial gauge. Numerical verifications are conducted to validate the proposed procedures, and the results show that they are efficient and reliable. It is also suggested that to weaken the influence of noise signal, measurements should be conducted at multiple axial positions.

The present work puts forward a generalized simulation model to evaluate the topography of ball-end milled surfaces by considering both the tool deflection and the tool runout. Firstly, a solid ball-end mill with S-shaped cutting edges is modeled as the basis. Then the tool tip trajectory is derived from the tool runout as well as the cutting forces induced tool deflection. And consequently the topography and scallop height of the machined surface are estimated by the numerical calculations of the matrix equations. With good expandibility, the proposed model can incorporate more machining information such as the movements of rotatory axes and tool wear, and hence, can be used to optimize the cutting conditions and parameters in 5-axis ball-end milling process.

The tool-workpiece contact zone is an important issue in the ball end milling process. This paper investigated the effects of tool inclination angles on the tool-workpiece contact zone, and variations of the cutting section area and perimeter with the increasing tilt and lead angles were also analyzed by geometrical modeling and measurement method for ball end milling process. The appropriate tool inclination angles, which could avoid the extrusion and friction between tool tip and the uncut materials, shorten the loading time on the cutting flute, and decrease the maximum cutting forces, could be preferentially selected according to the distribution characteristics of the tool-workpiece contact zone and the variations of the cutting section area and perimeter corresponding to various tool postures.
