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.

Factorial Design Of Experiments

This study focused on determining the residual stress of SAE 52100 hard-turned steel. The objective was to evaluate and compare the effects of the cutting-edge geometry and cutting parameters (cutting speed, feed rate, and cutting depth) on the residual stresses of three different conventional inserts: S-WNGA08 0408S01020A 7025, T-WNGA08 0408T01020A 7025, and S-WNGA432S0330A 7025. Tests were performed on 60 samples of SAE 52100 hardened steel with an average hardness of 58.5 HRC. The circumferential residual stresses of the samples were measured by X-ray diffraction. A full factorial design of experiments with three factors and two levels each with two central points and a replicate was used for a statistical analysis. The most significant results were as follows: For all inserts, the measured residual stresses were compressive, which extended the tool lifespan. The residual stresses of the Type-S inserts were significantly influenced by the cutting speed and depth, and those of the Type-T insert were significantly influenced by the feed rate and cutting depth. In addition, the residual stresses of the insert 3 were more compressive than those of the other two types of inserts. In other words, residual stresses are more compressive for inserts with larger chamfer angles even as the principal residual stress profiles were all compressive. This work has also shown that it is possible to determine a significant statistical relationship between cutting forces and residual stresses, allowing force measurements to predict the residual stress without any information on process parameters.

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.

Thermodynamic Relationship

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.

Three Components

An experimental study was carried out to investigate the effects of cutting parameters on cutting force and temperature in cutting of hardened W18Cr4V with PCBN cutter. Three components of cutting force were recorded by a strain-gauge dynamometer and the cutting temperature was measured by a nature thermocouple of tool-workpiece. The cutting parameters were arranged by orthogonal method. It is shown that the cutting temperature increased with each of the three cutting parameters and the main effecting factor is feeding speed. The three components of cutting force increased greatly with an increase in feeding speed and cutting depth. But the forces decreased a little as cutting speed increased. The main and axial cutting forces depend mainly on cutting depth whereas the radius force is mainly influenced by feeding speed.

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.
