The Role of Precision Engineering in Manufacturing of the Future

An experimental investigation of micro-machinability of copper 101 using tungsten carbide micro-endmills

“…Generally, the feeds in micromachining are in the range of 0.25-10 mm. 2 Copper 101 used in this study was defined by the ASTM B152 standard C10100 with 99.99% minimum purity and less than 0.0005% oxygen content.…”

“…There is a strong demand from various industries for miniature devices and components with complex microscale features fabricated on a variety of materials [1][2][3][4]. Some current applications from medical, aerospace, military, and transportation industries include miniature motors and turbines, micro-satellites, implantable and in vivo medical devices, minimally invasive surgery equipment, micro robots, miniature drone aircraft for reconnaissance missions, and miniature molds and dies.…”

Materials in machine tool structures

“…Since thermal stability, high stiffness and low masses are key issues in high and ultra-precision machine tools, also ceramics were used [184,185,283]. Table 4 gives an overview about characteristic values of some selected ceramic materials.…”

Laser beam machining (LBM), state of the art and new opportunities

“…Improvement of accuracy has been a central topic along 50 years of CIRP history as described by Peters et al [56], Merchant [57], McKeown [58] and many others. Short pulses have great potential to obtain higher accuracies in dimensional control because of the very small amounts of material that can be removed per pulse, as well because the very small damaged (heat-affected) zone at the surface.…”
