Blisks are important components of aircraft engines. Its machining plays an important role in a aerospace industry. Blisk processing efficiency has become a hot topic in the field of machining. Disk milling is a new processing method to achieve efficiency. In order to optimize disk milling process parameters of blisk, the use of full-factor experimental for researching TC4 titanium disc milling process. Analyze the impact of different cutting parameters on cutting force, the results show: during milling titanium by Discal Cutter, with the increasing of feed per tooth, the cutting force increases. But cutting forces in three directions has the different influence. Feed per tooth corresponding with radial cutting depth. In order to guarantee the material removal rate, it can be selected smaller feed per tooth and larger radial cutting depth. Through the stress simulation analysis on the blade, it can be carried out that the maximum strain of blade is concentrated at the tip arc. The equivalent stress is mainly concentrated at the main cutting edge and the tip arc. It can provide the basis for future tool design.

A method for predicting the stability of thin-walled workpiece milling process is described. The proposed approach takes into account the dynamic characteristics of workpiece changing with tool positions. A dedicated thin-walled workpiece representative of a typical industrial application is designed and modeled by finite element method (FEM). The workpiece frequency response function (FRF) depending on tool positions is obtained. A specific 3D stability chart (SC) for different spindle speeds and different tool positions is then elaborated by scanning the dynamic properties of workpiece along the machined direction throughout the machining process. The dynamic optimization of cutting parameters for increasing the chatter free material removal rate and surface finish is presented through considering the chatter vibration and forced vibration. The investigations are compared and verified by high speed milling experiments with flexible workpiece.

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.

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.

Optimization Of Cutting Parameters

Stainless steels have gained much attention to be an alternative solution for many manufacturing industries due to their high mechanical properties and corrosion resistance. However, owing to their high ductility, their low thermal conductivity and high tendency to work hardening, these materials are classed as materials difficult to machine. Therefore, the main aim of the study was to examine the effect of cutting parameters such as cutting speed, feed rate and depth of cut on the response parameters including surface roughness (Ra), tangential cutting force (Fz) and cutting power (Pc) during dry turning of AISI 316L using TiCN-TiN PVD cermet tool. As a methodology, the Taguchi L27 orthogonal array parameter design and response surface methodology (RSM)) have been used. Statistical analysis revealed feed rate affected for surface roughness (79.61%) and depth of cut impacted for tangential cutting force and cutting power (62.12% and 35.68%), respectively. According to optimization analysis based on desirability function (DF), cutting speed of 212.837 m/min, 0.08 mm/rev feed rate and 0.1 mm depth of cut were determined to acquire high machined part quality
