The experimental investigation on cutting tool wear and a model for tool wear estimation is reported in this paper. The changes in the values of cutting forces, vibrations and acoustic emissions with cutting tool wear are recoded and analyzed. On the basis of experimental results a model is developed for tool wear estimation in turning operations using Adaptive Neuro fuzzy Inference system (ANF...

In the current industry 4.0 scenario, good quality cutting tools result in a surface finish, minimum vibrations, low power consumption, and reduction of machining time. Monitoring tool wear plays crucial role manufacturing components. addition to monitoring, prediction assists systems making tool-changing decisions. This paper introduces an industrial use case supervised machine learning model ...

The tool wear of cutting tools has a very strong impact on product quality as well as on the efficiency of machining processes overall. Despite the current high automation level in the machining industry, a few key issues prevent complete automation of the entire turning process. One of these issues is tool wear, which is usually measured off the machine tool and is still done by hand under a t...

• Integration of computer vision and artificial intelligence for laser ablation. Automated method generating machining strategies to repair worn cutting tool inserts. Simple novel demonstration automated manufacturing reconditioning applications. In industry, cuttings tools are either discarded or recycled. However, recycling is a very energy intensive process. Reconditioning an alternative opt...

The tool wear is an unavoidable phenomenon when using coated carbide tools during hard turning of hardened steels. This   work focuses on the prediction of tool wear using regression analysis and artificial neural network (ANN).The work piece taken into consideration is AISI4140 steel hardened to 47 HRC. The models are developed from the results of experiments, which are carried out based on De...

Regenerative chatter is a major limitation in the milling of Ti-6Al-4V, resulting undesirable surface and reducing cutting efficiency. It well-acknowledged that variable pitch cutter process damping effect are effective methods to suppress chatter, these two compatible. In this paper, novel anti-vibration tool with combined (pitch angles 85°-95°-85°-95°) wear edges (60 μm on flank face), which ...

Compared with the conventional drilling, helical milling has obvious advantages in making holes of carbon fiber-reinforced plastic (CFRP). Nevertheless, rapid wear cutting edges readily causes some defects outlet holes, such as burrs and tearing. In order to improve hole-making quality CFRP, a comparative experimental study on ultrasonic-assisted bi-directional CFRP was carried out. The mechani...
