Abstract:

Stops to exchange cutting tool, to set up again the tool in a turning operation with CNC or to measure the workpiece dimensions have direct influence on production. The premature removal of the cutting tool results in high cost of machining, since the parcel relating to the cost of the cutting tool increases. On the other hand the late exchange of cutting tool also increases the cost of production because getting parts out of the preset tolerances may require rework for its use, when it does not cause bigger problems such as breaking of cutting tools or the loss of the part. Therefore, the rig

The problems related to the wear of the cutting tools wear and the tools life at the machining of the stainless steels are very important due to the chemical and mechanical characteristics of these steels [1]. Over time the research have studied the causes which produce the cutting tool wear and the methods to improve the cutting tools durability, either by creating new types of materials for tools, either by the choice of tools geometric parameters and cutting regime [2, 3].

The tool life is different when using different tool materials machine Ti6Al4V under different cutting conditions. Based on the experiments of cutting Ti6Al4V using different tool materials, the tool wear prediction model is established with BP neural network theory. The wear prediction model is verified by further experiments. The results show that there is a valid prediction interval when using BP neural network predicts tool wear. When the cutting speed is in the vicinity of the training sample data, the relative error of the tool wear prediction and experimental results is less than 10%, w

Abstract:

In batch production, recording the status of cutting tools and making decisions based on current tool status are important issues. In flexible manufacturing systems, there are normally many tools installed on machining centers. These tools are often used on different operations due to frequent change over in the system. The tool usage recording and the decision making based on tool status in this environment are crucial. The commonly adopted time measure is not sufficient because tool life is influenced by many factors. A tool status measure (tool wear index) is introduced in this paper. The i

Abstract:

A significant part of cost of machining is associated with non-optimum use of cutting tool. Moreover cutting tool failure is responsible for almost 20% of the machining downtime. Thus, having knowledge of residual life of cutting tool is highly recommended so as to maximise the availability time and reduce the machining cost. The aim of this work is to find out residual life of a worn cutting tool which has been used for turning of Ti-6Al-4V alloy under constant cutting condition.

The results showed that the carbide tool was not suit for the machining of TMC. Tool life of PCD was confined to 12 min for all the cutting conditions.

Abstract:

The life of a tool is very significant in metal cutting because production time is a waste whenever a tool is replaced or reset. Because of prolonged use, cutting tools blunt and their effectiveness decreases over time. It is necessary to replace, index or resharpen, and reset the tool after certain time. Tool life is a measure of the length of time a tool will cut effectively. The life of a cutting tool is mostly affected by many factors, such as, the tool wear, material removal rate, microstructure of the material being cut, setup rigidity, and cutting fluid quality.

The shape of cutting edge and cutting geometry changes in tool life due to wear. These geometrical changes of the tool are leading to non acceptable deviations from the demanded target geometry and a loss of cutting surface quality. Consequently the tool has to be inspected at regular intervals and be replaced or grinded if necessary. Prediction of such inspection intervals emerge as one of the challenges for an effective production. The inspection interval is dependent on tool life, which can be determined by cost intensive and elaborate experiments. Determination of a database containing too

Optimization of the economics of machining comprises the determination of the optimal cutting speed and tool replacement policy.

For the cutting edge preparation of milling tools, magnetic finishing is a promising process. This paper describes the process of magnetic finishing.

While it is now generally understood that in continuous chip forming processes such as turning, there is no magic high speed above which tool temperature decreases and tool life increases with increased cutting speed.

It is argued that in such an operation, the tool temperature oscillates between an ambient value at the beginning of a cut and a maximum value at the end of a cut. As cutting speed is increased, the cutting time per cut will decrease and hence the fractional appro

Abstract:

Accurate prediction of tool life is essential to guarantee surface quality and economics of cutting operations in face milling. This article presents a procedure for tool life prediction through in-process adaptation of tool wear rate based on indirect measures. The procedure effectively accounts for the uncertainty of tool wear progress owing to the complexity of the machining process. First, sensor fusion of spindle motor current AC and DC portions is taken to estimate the actual tool wear through relevance vector machine. Then, a tool life prediction model relating flank wear with cutting t

Abstract:

The service life of a diamond tool in cutting single-crystal silicon is normally very short because of severe tool wear. Therefore, it is important to use a proper coolant in order to restrain tool wear. In this paper, the performances of oil-based and water-based coolants were compared in silicon machining by investigating cutting forces and tool wear geometries. The water-based coolant was found to restrain flank wear more effectively than the oil-based one. The effective tool life using the water-based one was averagely three times longer than that using the oil-based one. The tool wear mec

Instead of one cutting edge in regular turning process, several cutting tools are used simultaneously in this assembly.

Abstract:

In this paper, a unique approach for estimating tool life using a hybrid finite element method coupled with empirical wear rate equation is presented. In the proposed approach, the computational time was significantly reduced when compared to nodal movement technique. However, to adopt such an approach, the angle between tool’s rake and flank faces must be constant through the process and at least two cutting experiments need to be performed for empirical model calibration. It is also important to predict the sliding velocity along the tool/flank face interface accurately when using Usui’s mod

Tools coated with TiBON films of varying boron concentrations were made, and the influence of boron concentration on tool wear was investigated. The TiBON coating film acts as a lubricant at high temperature. Tools coated with such films were applied to the machining of difficult-to-cut materials (Ti-6Al-4V and Inconel 718), where the cutting temperature increases rapidly and heavy adhesion occurs. In the experiment, turning and interrupted cutting were performed. In cutting of Ti-6Al-4V, the tool coated with a film of high boron concentration showed long tool life. In turning of Inconel 718,
