A judicious choice of insert material, tool geometry and cutting conditions can make hard turning produce better surfaces than grinding. In the present study, an attempt has been made to investigate the effect of cutting tool materials on cutting forces (feed force, thrust force and cutting force) in finish hard turning of AISI D2 cold work tool steel. In conclusion of the results obtained with...

This paper discusses the challenges involved in producing high-quality alumina ceramics, particularly when it comes to achieving a suitable degree of surface roughness and high accuracy. Alumina ceramics are widely used various applications due their exceptional properties, including strength, wear resistance chemical stability. The ceramic pistons with desired properties performance were produ...

RB-SiC ceramic is one of the most important and useful materials as optical precision elements in many scientific research fields. In this paper, a novel cold atmospheric plasma (CAP) process via oxygen (O2), which based on grinding surface technology to modify at room temperature for with combination oxidation modification, proposed. To identify performance proposed method modification fabrica...

background : in anterior endodontically treated teeth a better esthetic can be achieved by using all-ceramic post -core restorations instead of metal post systems. maximum retention and fracture resistance of the post are the criteria upon which selection of a post system is based. the aim of this study was to evaluate the fracture resistance and retention of two all-ceramic post and core syste...
