... Abstract Although carbon fiber reinforced plastics (CFRP) materials are widely used in high-strength and low-weight applications such as aerospace, defense, and automotive industries, they are one of the difficult-to-machine materials due to extensive tool wear. This paper investigates...

... Abstract In metal cutting process, modeling and predicting the tool wear development has been researched for decades. Many efforts have been made to study the cutting temperature as an indicator for the tool wear behavior. However, the determination of the cutting temperature in the critical...

... drills (twist drill and straight drill) were used to find out the influence of oil flow rate on the cutting performance. Tool life, tool wear, cutting force and torque were monitored as the cutting performance indicators. It was concluded that, the common belief of higher oil flow rate providing better...

... One of the most cost-effective dimensionally accurate processes used in manufacturing today, that is capable of producing a superior surface finish, is machining. As tooling wears, however, the advantages of machining greatly diminish. In addition, the time lost changing out the tooling...

... Tool wear development is an important parameter to control in order to obtain a specific surface integrity in machining operations. Unfortunately, it is difficult to accurately predict the tool life since wear rates generally exhibit a large scattering, and in consequence a scattering...

... parameters considered are material removal rate (MRR), surface roughness (R a ) and tool wear (TW). The significant parameters are identified individually using ANOVA and main effect plots. However, it is observed that the main goal of the manufacturers is to produce high quality products in shorter interval...

... a surface profilometer and the machined surface is observed using a scanning electron microscope (SEM). Chip morphology and tool wear are examined using an optical microscope. Cutting forces are measured using a three-component dynamometer. Based on the experimental results, it is found that the nHAP...

... 19 09 2011 The objective of this paper is to qualitatively assess the inadequacies of the current manner of tool wear quantification and consequently to suggest/develop a more comprehensive approach to machining tool wear characterization. Traditional parameters used for tool wear...

... was provided. After presenting the experiment procedures and workpiece properties, it reports the results on tool wear, cutting force, torque, surface roughness in RUM of stainless. Finally, it discusses and compares the performances of diamond and CBN tools in RUM of stainless steel under certain conditions...

... of tool wear and, thus, increase tool longevity are a vital component when improving the efficiency of machining processes. To this end, cryogenically treating cutting tools (especially high-speed steel tooling) is becoming more commonplace since research has shown that the treated tooling exhibits...

... recent progress in low-cost wireless sensor development, model calibration methods, model accuracy, and tool condition monitoring for SMS. We describe a system that can estimate tool wear using the coefficients of a tangential cutting force model. The model coefficients are estimated by online...

... 22 09 2010 Machining wear models are useful for the prediction of tool life and the estimation of machining productivity. Existing wear models relate the cutting parameters of feed, speed, and depth of cut to tool wear. The tool wear is often reported as changes in flank width...
