Tool life of diamond inserts after laser assisted turning of cemented carbides

Abstract

Abstract:The paper presents results and discussion on parameters influence on tool life when turning laser cladded cemented carbides under laser assisted machining (LAM) conditions. The layers are known as Technolase 30S. This material is widely recognized as hard-to-cut. The experimental investigation was carried out with diamond inserts. The laser power density, feed rate and laser scanning speed were analysed. Flank wear (VBc) indicator was measured and cutting tool life was calculated. It was proved that Technolase 30S can be machined with LAM technology. The laser enhanced turning is more efficient than conventional turning and grinding.

Applying a Traditional Casting Defect Classification to Categorize Casting Defects in Metal Matrix Composites with Saturated Reinforcement

“…The proposed classification, including both ontology and taxonomy, may be interesting not only in the material [30] area, but also in the mechanical [31][32][33] and technological [34,35]…”

Tool Wear Prediction Based on Artificial Neural Network during Aluminum Matrix Composite Milling

“…In addition to the right selection of tool material, unconventional machining improved cutting performance is common. One of the used methods is the electrical discharge machining (EDM), laser machining (LAM), electrochemical machining, ultrasonic machining (USM), and high-speed machining [ 27 , 28 , 29 ]. According to [ 30 ], Chwalczuk et al shows the optimization of heating and cutting parameters during turning of Inconel 718 under laser-assisted machining (LAM) conditions.…”

Improvement of the Surface of the Combustion Chamber of a Piston using Selected Techniques of Production Organization

“…The presented approach may be useful in other industrial and research activities that have problems with the occurrence of defects, e.g. biotechnology [18,19], heat flows [20], hydraulic equipment of heavy duty machines [21], tools production [22] and improving their characteristics, in particular the surface layer [23][24][25]. It should be taken into account in related analysis e.g.…”
