Optimization Of Cutting Parameters

The measurement method and apparatus of cutting force by high speed milling is introduced. The high speed milling force of wrought aluminum alloy is measured and analyzed through separately examining the influences of various factors, such as cutting speed, cutting depth, milling width, feed per cutting tooth, down or up milling, cooling and lubricating. The results match with outcomes from other’s tests and the theory of metal cutting, and are close to the calculated force values, so that the test can be regarded as positive. It is pointed out that high cutting speed, little cutting depth, properly great working engagement and feed per tooth, high feed rate, down milling and efficient cooling and lubricating should be used to reduce cutting force and deformation, to improve milling accuracy and efficiency, which can be helpful to the spread applications of High Speed Machining.

High Cutting Speed

Experiments were carried out to investigate the cutting force and tool wear behavior of Sialon ceramic tools in high speed milling of GH4169 under different cutting parameters. The cutting speed exhibited the most significant influence on the cutting force. The cutting force decreased firstly then increased with the increasing of cutting speed. And the effect of feed speed and cutting depth on cutting force were also discussed. The worn surfaces of tool were examined and the elements on the tool surfaces were analyzed by employing scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS), respectively. The analysis results of the SEM and EDS showed that the dominant wear pattern were rake face flaking and notching at the low cutting speed while flank wear was the main wear type at the high cutting speed of 1037m/min.

This paper presents the experimental results of cutting force and surface roughness of 7050-T7451 aluminum alloy under the cutting speed of 3000~5000m/min. The cutting forces and surface roughness with different cutting parameters were analyzed. Experimental results suggested that increasing cutting speed would engender thermal softening, which would in return affect the cutting force and surface roughness in high speed milling. The cutting force and surface roughness were affected by cutting depth and feed rate obviously. Surface roughness was also affected by cutting width which changed the cutting force slightly. According to the results, proper parameters could be selected and thermodynamic relationship needed to be discussed for further research.

An experimental study was conducted to determine cutting parameters of high-speed milling of Ti-17 according to their effects on residual stresses. First, three groups of single factor experiments were carried out to reveal the effects of cutting parameters on residual stresses. Then sensitivity models were established to evaluate the influence degrees of cutting parameters on residual stresses. After that, three criteria were proposed to determine cutting parameters from experimental parameter ranges. In the experiments, the cutting parameter ranges are recommended as [371.8, 406.8] m/min, [0.363, 0.412] mm and [0, 0.018] mm/z for cutting speed, cutting depth and feed per tooth, respectively.

Milling Forces

Cutting forces is one of the important physical phenomena in metal cutting process. It directly affects the surface quality of machining, tool life and cutting stability. The orthogonal experiments of cutting forces and influence factors with indexable and solid end mill were accomplished and the predictive model of milling force was established during high speed end milling 7050-T7451 aluminum alloy. The paper makes research mainly on the influence which the cutting speed, cutting depth and feed have on the cutting force. The experimental results of single factor showed that the cutting forces increase earlier and drop later with the increase of cutting speed, and the cutting speed of inflexion for 7050-T7451 is 1100m/min. As axial cutting depth, radial cutting depth and feed rate increase, the cutting force grows in different degree. The cutting force is particularly sensitive to axial cutting depth and slightly to the radial cutting depth.

Titanium Alloy Ti6al4v

Titanium alloys are widely used in aviation and aerospace industry due to their special mechanical properties. In the process of machining titanium alloys, cutting force is an important physical quantity. In this paper, a series of experiments were carried out to investigate the cutting force in detail during high feed milling of titanium alloy Ti6Al4V with different high feed cutters. Effects of cutting parameters, such as milling speed, feed per tooth, radial cutting depth and axial cutting depth on cutting force were analyzed. The results showed that cutting force presented an obvious increasing trend with the increase of feed per tooth and axial cutting depth. However, the effects of cutting speed and radial cutting depth on cutting force were not obvious.

The Impact

Most aerospace parts are thin walled and made of aluminum or titanium alloy that is machined to the required shape and dimensions. Deformation is a common issue. Although the reduced cutting forces used in high-speed milling generate low residual stress, the problem of deformation cannot be completely resolved. In this work, we emphasized that choosing the correct cutting parameters and machining techniques could increase the cutting performance and surface quality and reduce the deformation of thin plates. In this study, a part made of a thin 6061 aluminum alloy plate was machined by high-speed milling (HSM), and a Taguchi L16 orthogonal array was used to optimize the following parameters: linear velocity, feed per tooth, cutting depth, cutting width, and toolpath. The impact of cutting parameters on the degree of deformation, surface roughness, as well as the cutting force on the thin plate were all investigated. The results showed that the experimental parameters for the optimal degree of deformation were A1 (linear velocity 450 mm/min), B1 (feed per tooth 0.06 mm/tooth), C1 (cutting depth 0.3 mm), D4 (cutting width 70%), and E4 (rough zigzag). Feed per tooth was the most significant control factor, with a contribution as high as 63.5%. It should also be mentioned that, according to the factor response of deformation, there was a lower value of feed per tooth and less deformation. Furthermore, the feed per tooth and the cutting depth decreased and the surface roughness increased. The cutting force rose or fell with an increase or decrease of cutting depth.
