Narrow Results

Most of the researchers have developed Artificial Neural Network (ANN) models to forecast the cutting tool life based on whether it has either a flank wear or a crater wear or a nose wear. In this paper, an attempt has been made to classify the cutting tool wear based on whether it has flank wear, chipped-off cutting edge or a combination of both failures. To obtain the experimental results, both the failures namely flank wear and chipped-off cutting edge have been produced using Electric Discharge Machining (EDM) process. Experiments were carried out using cemented carbide-coated inserts on EN-8 steel and all the responses were acquired by using virtual instruments. The acquired data were analyzed to develop the ANN models to forecast the condition of cutting tool. Vibration and strain data were recorded using accelerometer and strain gauge half-bridge circuit.

The boiler's steam pipes are a vital component of the steam-water piping system. As these pipes usually work under abnormal conditions due to deformations caused by the environment's high temperature and pressure, they must be effectively monitored. The digital image correlation method has increasingly been used for thermal deformation in recent years. Compared to traditional gauges, this method is both easier to implement and less costly. Analysis software processes the images and calculates strain automatically. Based on this method, an algorithm for strain computing is proposed, and a model for pipe deformation is presented. Required measurement steps are explained and the experimental results are reported. The used algorithm is explained and its reliability is discussed. Experimental results show that the method is both feasible and reliable.

Tubing is a key component of continuous initiation device for perforating. Relief of high energy to tubingis after starting the device. Tubing guarantees for propagation of detonation wave in dissection. Technical parameters, such as equivalent stress, strain, deformation as well as volume fluctuations were discussed bymeans of finite element method. The study indicates that the calculation model and simulation method are reasonable and feasible, so can be applied to the optimizing design for shaped charge jet, which may be used for reference to manufacture and scientific research of perforating bullet.
