Abstract The tool geometry is generally of great significance in metal cutting performance. response surface method was used to optimize chamfer achieve reliable and minimum wear slot milling. Models were developed for edge chipping, rake wear, flank wear. adequacy the models verified using analysis variance at a 95% confidence level. Each optimized individually, multiple responses simultaneous...

The aim of this work is to analyze the micro mechanisms underlying the wear of macroscale tools during diamond machining of SiCp/Al6063 composites and to develop the mechanism-based diamond wear model in relation to the dominant wear behaviors. During drilling, high volume fraction SiCp/Al6063 composites containing Cu, the dominant wear mechanisms of diamond tool involve thermodynamically activ...

This paper describes the development of a machine vision system for automated tool wear inspection. The proposed approach measures the tool wear region based on the active contour algorithm and classifies the wear type by means of neural networks. Test results show that prevalent tool wears can be checked robustly in a real production environment and therefore the manufacturing automation can b...

Machining-induced white layers and severely deformed are undesirable surface integrity features which can be formed when machining high-strength aerospace alloys. An orthogonal milling process has been designed performed to assess the impact of cutting speeds, tool wear, edge radius climb vs conventional on layer formation plastic strain distribution. The deformation in machined associated with...

Composite materials made of fiber-reinforced plastic laminates are highly susceptible to surface damage caused by wear during contour milling, especially with inappropriate tool and cutting material properties. Improper choice tools conditions lead delamination between applied layers, thermal in the polymer matrix, reduction edge quality tools. The study was devoted circumferential milling twil...

High-speed machining of γ-TiAl alloy is a significant challenge due to high cutting temperatures. From the perspective environmental protection and improving tool life, appropriate cooling strategies should be adopted. Compared with dry conventional flood conditions, feasibility in cryogenic LN2 conditions was discussed. The force, wear its mechanism, surface roughness, as well sub-surface morp...

Abstract Metal-polyamide gear pairs provide advantages but their application is limited due to wear. The properties of the metallic gearing significantly affect wear behavior. However, influence varying materials as well flank hardness not known. Within this contribution, occurring mechanisms when applying steel, brass and aluminum with resulting from manufacturing by machining cold forging wer...

An experimental study has been carried out to investigate and compare the cutting tool performances represented by insert wear, surface roughness forces of an uncoated carbide (H13A) three coated carbides GC2015 ( TiCN / Al2O3 TiN ), GC1015 (TiN) GC4215 ) during dry turning AISI4140 steel. Turning was 5 minutes on cylindrical specimens (80 mm diameter 400 length) along with a depth 0.5 mm, feed...
