“…In deformation machining, as identified by Smith et al (2007), thin features are machined to the desired accuracy by milling. Forming operations are then carried out to create deformations of the thin sections by bending or stretching the features to finally form the designed shapes.…”

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.

This study proposes a method to adapt the geometry of the toolpath to a specified target. In the case study presented, the geometrical target is to remove a constant thickness on the rough workpiece. This case is normally present in the polishing of the femoral component of knee prostheses. In fact, an operator carries out these operations manually. The aim of this study is to contribute to the automation of prosthesis production, notably, in the preparation of surface polishing. The proposed method can deform and adapt a toolpath to ensure the required geometry of the machined surface. The proposed toolpath deformation method is composed of three steps: alignment, toolpath deformation, and toolpath smoothing. Alignment between the measured surface of the roughcast prostheses and the nominal toolpath is carried out by an Iterative Closest Point (ICP) algorithm. The principle of this algorithm is to find the optimal rigid transformation to readjust the toolpath on the measured surface. Subsequently, the toolpath is deformed to remove the constant thickness of the roughcast prostheses. Next, to increase the machined quality, a smoothing stage is carried out on the obtained toolpath. Experimental tests on industrial prostheses geometry are conducted to validate the effectiveness of this method.

“…Then using a forming tool single point incremental forming is used to create deformations of thin sections in two different ways, by bending the features or by stretching. Deforming between the cutting tool and the deformation tool, this hybrid combination allows making interesting features which are thinner, lighter or less expensive than the structures they replace, and which have novel geometries that were previously not possible [8].…”

Necessity to use new materials, demanding functional requirements and miniaturization have led to evolution of modern manufacturing processes. Developments are taking place both in the conventional methods and unconventional methods of manufacture. High speed machining, hard machining, non conventional processes like beam, mechanical and chemical processes and additive processes like rapid prototyping are some of the modern manufacturing processes. This paper aims to give overview of modern manufacturing processes that are currently under use/research in the manufacturing arena.
