The use of titanium and its alloys has increased in various industries recently, because of their superior properties of these alloys. Titanium alloys are generally classified as difficult to machine materials because of their thermo-mechanical properties such as high strength-to-weight ratio and low thermal conductivity. Laser Assisted Machining (LAM) improves the machinability of high strengt...

A critical aspect of smart machining systems is the appropriate management of knowledge and information to support effective decision-making. The uncertainty of model-based predictions of machining performance plays an important role in decision-making for machining optimization and adaptive control optimization. This paper presents a technique for managing modeling and measurement uncertaintie...

This paper presents simulation of High Speed Machining of steel with coated carbide tools. More specifically, Third Wave Systems AdvantEdge commercial Finite Element Method code is employed in order to present turning models, under various machining conditions. As a novelty, the proposed models for High Speed Machining of steel are three-dimensional and are able to provide predictions on cuttin...

Scheduling under controllable machining conditions has been studied for some time. Scheduling with tool changes, particularly due to tool wear, has just begun to receive attention. Though machining conditions impact tool wear and induce tool change, the two issues have not been considered together. We address for the first time the problem of scheduling a computer numerically controlled (CNC) m...

In view of the high investment and tooling cost of a CNC machining centre, the cutting and idle times should be optimised by considering the tool consumption and the non-machining time cost components. In this paper, we propose a detailed mathematical model for the operation of a CNC machine tool which includes the system characterisation, the cutting conditions and tool life relationship, and ...

In this study, we determine the upper and lower bounds for the processing time of each job under controllable machining conditions. The proposed bounding scheme is used to find a set of discrete efficient points on the efficient frontier for a bi-criteria scheduling problem on a single CNC machine. We have two objectives; minimizing the manufacturing cost (comprised of machining and tooling cos...

ABSTRACT The objective of this investigation is to obtain an optimal setting of process parameters in turning for maximizing the material removal rate of the manufactured component. The material removal rate has been investigated in this analysis while machining practically used components. As per Taguchi’s “Design of Experiments”, the number of experiments to be conducted in this analysis is c...

Sustainable production as a global word, content important elements on all the fields as well as machining processes. Machining can be performed either on conventional or nowadays modern CNC way. Novel machining processes are based on CNC programmable technologies containing elements as CAD, CAM, etc. To define sustainable production as the creation of goods, using processes and systems, we hav...

This paper presents a rage of variable machining factors which influence substantially friction directly or by the abrasive media wear developed in cutting zone. Abrasive flow is method surfaces complex holes and curved surface. In case traditional stream treatment methods (AFM) it difficult to obtain uniform roughness radial decomposition during polishing complicated openings, results from une...
