Adopted the cutting-contact model of high speed ball-end milling hardened steel surfaces, researched distribution characteristics of cutting-contact stress; by researching the influence of the distribution of this stress on cutter wear, clarified the influence theory of milling pattern and cutting parameters on initial wear of milling cutter. By using the method of climbing, conventional milling alternating and changing cutting parameters, verified the influence of milling pattern and cutting parameters on initial wear pattern. The result showed that, initial wear mechanism of high speed milling hardened steel is an interaction of multiple wear mechanisms under the effect of friction and alternating pressure stress, by using conventional milling can significantly reduce concave curvature radius of hardened steel, the contact stress of blade area and front, rear flank, inhibit crushing and wear rate of the milling cutter surfaces. Under this condition, by increasing rotation speed and reducing the feed per blade, will further increase the strength of this effect, and achieve the purpose of reducing the initial wear, inhibiting the wear rate and extending the cutters life.

In order to depress cutter vibration caused by high hardness and periodic change of cutting force in high speed milling complex surface, investigated the modal characteristics of ball-end milling cutter through the modal analysis and transient analysis. Using the models of dynamic cutting force and cutting vibration, acquired dynamics characteristics of high speed ball-end milling cutter by the spectrum analysis of dynamic cutting force, simulation analysis of cutting vibration and experiment of high speed milling hardened steel. Results indicate that high speed ball-end milling energy concentrates in few special frequencies, the rotational speed and the numbers of cutter teeth determine the fundamental frequency. High speed ball-end milling cutter easily makes radial bending vibration by the lower modal characteristics, the overhang and inclination angle of cutter affect its dynamics characteristics significantly, and the modal parameters and vibration model of cutter acquired by step response method have higher credibility.

Coupling Behavior

The high-speed milling of titanium alloy is a very complex nonlinear dynamic cutting process, and there are mutual coupling effects between multiple physical fields of the tool. Therefore, the thermo-mechanical coupling behavior of micro-textured ball-end milling cutters during the cutting of titanium alloy was studied in depth, combined with theoretical calculations, milling experiments and simulation analysis. First, based on the experimental data of milling titanium alloy, the stress field of the micro-textured ball-end milling cutter was solved. Then, the dimensional method was used to solve the temperature field of the micro-textured ball-end milling cutter. Finally, the thermo-mechanical coupling simulation analysis of the micro-textured ball-end milling cutter was carried out, and the stress concentration area and tool breakage area of the micro-textured ball-end milling cutter under the thermo-mechanical coupling effect are obtained. This in turn gives a theoretical basis for further improving the performance and tool life of micro-textured cutters.

The Impact

For the instability of ball-end milling cutter in high speed milling, instantaneous cutting process of high speed milling hardened steel was studied. The model of instantaneous cutting layer parameters of high speed ball-end cutter was established, and the influence of cutting speed and inclination angles on instantaneous cutting layer parameters were obtained. Using the model, instantaneous cutting force was studied, and high speed milling experiment was processed. Results show that the increase of cutting speed makes the change rate of cutting layer parameters increasing, leads to the energy concentration in cutting process, and increases the impact on milling cutter. The increase of inclination angle makes the instantaneous cutting layer parameters show a trend of decrease and the decrease of cutting thickness more rapidly, which caused instantaneous unit cutting force to increase and the instantaneous main cutting force appears increasing trend, and the cutting process become unstable.

An experimental study on wear and fracture of ball-end milling cutter in high speed machining martensitic stainless steel 0Cr13Ni4Mo is studied in this work. Through the SEM micrographs and energy spectrum analysis of the wear pattern of the rake face, severe coating spalling is found near the main cutting edge. Fracture is seen on the entire cutting edge, in which micro-chipping occurs on the both ends of the cutting edge, and chipping occurs in the middle of the cutting edge and is the conchoidal spalling on the rake face. Combined with the high-speed photography of the milling process, the fracture area is consistent with the chip-adhesion area.

Abstract The analysis of the surface topography in ball end milling is an objective studied by many researchers, several methods were used and many combinations of cutting conditions and machining errors are considered. In the milling tool paths the trajectories presents a points of changing direction where the tool decelerates before and accelerates after respecting the velocity profiles of the machine. In this paper, we propose experimental investigations of the effect of the kinematic behavior of the machine tool on the surface quality. A poor topography and roughness are remarked on the deceleration and the acceleration zones compared to the stationary zone.
