Abstract:

Laser engraving is a widely used technique for bamboo applications. However, the literature lacks a recommended standard roughness parameter or a numerical comparison between samples for a quantitative assessment of surface texture post-engraving. In this research, we systematically evaluated well-known 2D roughness parameters typically used for metal parts and measured them for laser bamboo engraving under various laser conditions. We utilized a pulsed laser with a 450 nm wavelength and 5.5 W power to engrave bamboo specimens, examining the surface roughness at different speed and power combi

Abstract:

Mechanical vibrations represent an important problem in machining processes performed by machine tools. They affect surface quality, tool life, and productivity. In extreme situations, chattering may appear, which can dramatically reduce the tool life. CNC router machines are particularly sensitive to vibrations, with their structure bearing resemblance to a composition of beams that are uniform in cross-section. These CNC machines are commonly used for different tasks, like engraving, cutting, and 3D printing. This work proposes a modeling methodology for vibration systems that consist of cou

The method of construction and attestation of a numerical model of cold stamping of thin-walled products made of anisotropic metal sheet for the design of technological operations is proposed. The relations of the associated law of plastic flow with the Barlat flow function and isotropic strain hardening are used. The method of design and processing the experiment is proposed for their identification. The forming limit curve is approximated numerically by the Marciniak - Kuczynўski method, and for its identification it is proposed to use a failure test under uniaxial tension and press equipmen

Engraving is a process of sculpting, carving and scratching a pattern. In ancient times the art of wood carving became a symbol of status of noble and courtiers. According to Halim Nasir (1986) the courtiers and sultans became patrons to revive the glory of wood carving. This shows that wood carving is high dignity. The Malays emphasizes every work of art and is designed by the soul attempts to communicate with the public in feel, thinking and interpretations, (Nazzri, 2016). However, the price of traditional wood carving product is too high and difficult to educate the public to love wood car

AbstractThe inscription of the statuette from Knossos, Heraklion Archaeological Museum Λ 95, has proven over the years to be exceedingly difficult for the correct identification of its hieroglyphic signs. The signs vary widely in their quality of engraving, with some being so small and shallow that they cannot be recognized at all by traditional techniques, and the stone’s surface shows evidence of ‘staining’ after many centuries of burial in the temperate soil. Furthermore, it appears that some signs were never actually completely engraved, with what appears to be remnants of the original mar
