“…Depending on the accuracy achieved, these applications are traditionally referred to as 'precision machining' or 'ultraprecision machining'. When the amount of material removed becomes increasingly small, the transition to nano-machining is made, which is an important branch of nanotechnology [3]. Electron beam lithography and X-ray lithography combined with chemical etching, electroplating and moulding (LIGA) are the enabling technologies for the fabrication of microelectronics and microsystems [4].…”

“…The simulation revealed that during polishing an amorphous interface layer is formed ( figure 16). Because carbon atoms disrupted from the lattice undergo a transition from sp 3 to sp 2 or sp bond hybridization, they can form strong bonds with atoms sitting at the surface of the lattice, eventually pulling them into the growing amorphous layer. Thus, the surface activation by amorphous carbon atoms is the key for understanding the polishing process.…”

Manipulating bulk material at the atomic level is considered to be the domain of physics, chemistry and nanotechnology. However, precision engineering, especially micromachining, has become a powerful tool for controlling the surface properties and sub-surface integrity of the optical, electronic and mechanical functional parts in a regime where continuum mechanics is left behind and the quantum nature of matter comes into play. The surprising subtlety of micro-machining results from the extraordinary precision of tools, machines and controls expanding into the nanometre range-a hundred times more precise than the wavelength of light. In this paper, we will outline the development of precision engineering, highlight modern achievements of ultra-precision machining and discuss the necessity of a deeper physical understanding of micro-machining.

“…With technology everything was difficult in the past become easy now (Harris, 2004) .It is hard to confine technology in one side .Actually, it has many sections and types in every field (Mostafapour, Rezaei, & Ghabousi, 2012) .We know that nanotechnology is one of the important technologies in this world. It has many applications in many different fields such as energy, Nano devices, Nano fabrics, and Nano bio technology (Corbett, McKeown, Peggs, & Whatmore, 2000). In fact, Nano medicine is one of the important nanotechnology applications (Murday, Siegel, Stein, & Wright, 2009) and (M. Chen, Lin, & Cheng, 2013) .…”

“…The curves presented by [3] and updated recently by McKeown [4] in Figure 2 (in simplified form) trace the development in manufacturing capability in terms of achievable machining accuracy since the 1940's. Today, ultra-precision machine tools under computer control can position the tool relative to the workpiece to a resolution and positioning accuracy in the order of 1nm.…”

This paper reviews some of the main developments in cutting technology since the foundation of CIRP over fifty years ago. Material removal processes can take place at considerably higher performance levels in the range up to Q w = 150 -1500 cm 3 /min for most workpiece materials at cutting speeds up to some 8.000 m/min. Dry or near dry cutting is finding widespread application. The superhard cutting tool materials embody hardness levels in the range 3000 -9000 HV with toughness levels exceeding 1000 MPa. Coated tool materials offer the opportunity to fine tune the cutting tool to the material being machined. Machining accuracies down to 10 µm can now be achieved for conventional cutting processes with CNC machine tools, whilst ultraprecision cutting can operate in the range < 0.1µm. The main technological developments associated with the cutting tool and tool materials, the workpiece materials, the machine tool, the process conditions and the manufacturing environment which have led to this advancement are given detailed consideration in this paper. The basis for a roadmap of future development of cutting technology is provided.
