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.

Optimal Cutting Parameters

In this study AISI 1045 steel of different hardness are used in high speed milling. According to Taguchi method, cutting parameters (milling speed, milling depth, feed per tooth) and workpiece hardness for the influence of high speed milling of the surface roughness are optimized. Through this study, not only the optimal cutting parameters of the minimum surface roughness is obtained, but also the main cutting parameters that effect performance in high speed milling is analysed. Researching results can be provided to guide establishment of the high speed milling process.

Optimization Of Cutting Parameters

A semi-artificial thermocouple device is developed to explore the dynamic cutting temperature variation rules in high-speed milling of Al7050-T7451 aluminum alloy. Both the aluminum-constantan thermocouple calibration diagram and cutting temperature curves are obtained. The cutting temperature empirical formula is constructed by means of orthogonal experimental design and multivariate linear regression analyses. It shows a reasonable good match between the theoretical predicted values and the measured temperatures. This allows for the optimization of cutting parameters and the exploration of machining deformation induced by the cutting heat in high-speed milling of aerospace aluminum monolithic constructions.

Optimization Of Cutting Parameters

Machining operations of thin-walled elements generate a lot of production process issues related to deformations and elastic and plastic displacements of the workpiece. Due to displacements of the milled workpiece, vibrations can occur, and thus, geometric errors may occur on surface in the structure of the workpiece. Furthermore, plastic deformation can also cause shape problems and be a source of internal stresses in the surface layer, which are highly difficult to remove and lead to deformation of the workpiece after machining. Consequently, this leads to an increase in the manufacturing costs of machining operations, especially of thin-walled elements, due to shortages and increased manufacturing time. It is recommended that multiple methods for minimizing machining errors be utilized to improve the quality of thin walled elements, such as: optimization of the machining strategy, increase of the cutting speed vc, optimization of cutting parameters, especially feed per blade fz, the radial depth of cut ae due to the minimization of the cutting force component perpendicular to the surface of the milled wall.

High-speed machining thoroughly hardened tool steels has emerged as a competitive finishing technology for making dies and molds. The objective of this paper is to develop an optimization method for the better (i. e., lower value) surface roughness in terms of cutting parameters when high-speed milling hardened H13 steel. The cutting parameters to be considered were cutting speed, feed per tooth, radial depth of cut, and axial depth of cut, respectively. A series of high-speed milling experiments of hardened H13 steel using PVD coated carbide inserts without any cutting fluids were performed to measure the surface roughness data. Taguchi orthogonal arrays, signal-to-noise (S/N) ratio, and analysis of variance (ANOVA) were used to evaluate the effects of cutting parameters on surface roughness and to find the optimal factor/level combination for the better surface roughness. The investigations of this study would be used for design optimization of cutting parameters to obtain the better surface roughness.
