“…The tool life (TC tools) can be improved in a range of 60-100 % for hardened steel [100] and CGI, respectively [103]. This improvement can be reached to 180 % for PCD tool against composites [95]. For testing the tool wear, ISO3685 standard is a scientific choice.…”

Laser beam machining (LBM) has proven its applications and advantages over almost all the range of engineering materials. It offers its competences from macro machining to micro and nano-machining of simple-to-complex shapes. The flipside of LBM is the existence of universal problems associated with its thermal ablation mechanism. In order to alleviate or reduce the inherent problems of LBM, a massive research has been done during the past decade and in turn build a relatively new route of laser-hybrid processes. The hybrid approaches in laser ablation have demonstrated much improved results in terms of material removal rate, surface integrity, geometrical tolerances, thermal damage, metallurgical alterations and many more. This chapter reviews the research work carried out so far in the area of LBM and its hybrid processes for different materials and shapes.

On the mechanism of two-body abrasive wear in turning “the spin-split theory”

This approach regarding metal cutting in steel reveals the likely mechanisms behind a two-body abrasive wear. The theory is based on the assumption that ceramic hard inclusions in the secondary and tertiary cutting zones cannot to any significant extent be deformed plastically. The inclusions, in most cases roundish bullet-type particles, are forced to rotate or break due to the large shear stresses in the cutting zones. A bullet-type particle cannot efficiently cut or wear on the cutting tool rake and tool flank, but when the particle is torn apart, efficient sharp edges are created. Those edges are then, due to the elongation and contraction of the matrix material, pressed out towards the cutting tool, where they, while still rotating, cut until their cutting geometry become less favourable and at that point break into small fragments, which together with the matrix material are welded on the tool clearance and the tool rake faces. Those deposits with particle remnants and chips from the cutting tool contain 30-40% of ceramic material. The rest is matrix material from the workpiece. The understanding of this mechanism opens new ways to improve cutting materials, both coating and substrate, and the workpiece materials.

Today, hybrid manufacturing technology has drawn significant interests from both academia and industry due to the capability to make products in a more efficient and productive way. Although there is no specific consensus on the definition of the term 'hybrid processes', researchers have explored a number of approaches to combine different manufacturing processes with the similar objectives of improving surface integrity, increasing material removal rate, reducing tool wear, reducing production time and extending application areas. Thus, hybrid processes open up new opportunities and applications for manufacturing various components which are not able to be produced economically by processes on their own. This review paper starts with the classification of current manufacturing processes based on processes being defined as additive, subtractive, transformative, joining and dividing. Definitions of hybrid processes from other researchers in the literature are then introduced. The major part of this paper reviews existing hybrid processes reported over the past two decades. Finally, this paper attempts to propose possible definitions of hybrid processes along with the authors' classification, followed by discussion of their developments, limitations and future research needs.
