Toolpath dependent stability lobes for the milling of thin-walled parts

Abstract: The milling of thin-walled parts can become a seriously complex problem because the parts have variable dynamics. Firstly, the dynamics evolution of the part has been calculated through Finite Element Method (FEM) analysis. Then, the 3D stability lobes have been calculated for the thin walls and the thin floor. Finally, several milling tests have been performed in order to validate the predictions made by the model.

Accompanying phenomena in the cutting zone machinability during turning of stainless steels

Abstract: The rapid development of industry is marked by the development and application of new materials with characteristics that broaden their applicable uses. Therefore, it is natural that advances in machinability attract a considerable interest even today. Precise and reliable information on the machinability of a material before it enters the machining process is a necessity and hypotheses must be tested through verification of actual methods. This article presents conclusions of machinability tests on austenitic stainless steels 1.4301 and describes appropriate parameters for the cutting zone during the process of turning. The article focuses on the analysis of selected domains through four basic some parameters of steel machinability.

Machining of austenitic stainless steels – a review

Abstract: Although austenitic stainless steels have been used in the largest volumes of all the five families of stainless steel, and are characterised by high ductility, high durability and excellent corrosion resistance, they have certain disadvantages that act as constraints in certain applications. These steels are considered as the most difficult-to-cut materials as compared to the other alloy steels due to their high work hardening, low heat conductivity and high built up edge (BUE) formation. Some important concepts in the metallurgy of austenitic stainless steels are briefly introduced in the present paper, and some of the problems associated with the machining of austenitic stainless steels are also brought forward. Also a review is made of the various works of researchers in this context. Finally, this paper concludes with a discussion on future research areas.

Machinability and surface quality during high speed trimming of multi directional CFRP

Abstract: In this paper, high speed trimming of a multidirectional CFRP using unused and used burr tools is considered in order to investigate the influence of the machining parameters (e.g., feed speed, cutting speed and cutting distance) on the cutting forces, machining temperature, and the machined surface quality. To estimate the effect of the tools’ wear and cutting parameters on the cutting forces and surface roughness, a statistical method (ANOVA) has been used. When considering an unused tool, the recorded temperatures were below the glass transition temperature of the composite material (Tg). In the case of used tools, these temperatures were mostly higher than the Tg. Furthermore, SEM observations of the machined surface showed damaged areas. These areas were wider when the cutting distance increased. Statistical analyses have shown that the machining parameters have a significant influence on the variation of the machined surface quality and the cutting forces.

Experimental investigation and optimisation in EDM of Al 6063 SiCp metal matrix composite

Abstract: Al 6063 SiCp metal matrix composite (MMC) was drilled by EDM to assess the machinability and obtain an optimal setting of process parameters. The effect of pulse-on (Ton), pulse-off (Toff), pulse current (Ip), gap control setting and flushing pressure on EDM of cast Al 6063-SiCp MMC was investigated. The machining conditions were identified for machining performance of the EDM process with respect to material removal rate (MRR) and tool wear rate (TWR) by pilot experimentation using one-factor-at-a-time approach. Taguchi's technique was further applied to obtain an optimal setting of the EDM process parameters. The experimental results and subsequent analysis revealed that all the selected process parameters were significant. MRR increases with increasing Ip and Ton up to an optimal point and then drops. The effect of Ip is predominant on MRR as compared to other parameters.
