Explanation: The difference in outer and inner circumference of the generating gear causes an extreme tooth thickness taper that leads to uneven tooth profile.

Explanation: Several types of materials are used in the manufacture of the forming rolls and oil hardened tool steel being the most common. For extended tool life, hardened high-carbon, high-chromium too steels are used. On extremely tough forming applications involving high temperatures and or abrasive materials, aluminium/bronze or carbide rolls are required.

(7) High MRR’s when grinding hard, tough, stringy, work-hardenable or heat sensitive materials.

Explanation: Shaping the tool is usually not a problem since all the materials are easy to machine. Cold forging and electroforming are favourable methods of tool making.

Explanation: Following the International Union of Pure and Applied Chemistry (IUPAC) nomenclature used to classify porous materials as a function of their pore size (dp).

Explanation: The reason why the pore characteristics of the resulting pSi structures depend upon the doping type and its level of the silicon wafer is that the pore formation mechanism relies on these parameters.

Explanation: Micro-turning, micro-milling and micro-grinding are traditional material removal processes; whereas, micro-EBM (micro electron beam machining) process is one of the advanced manufacturing processes.

Explanation: Reduced hole diameter, lower hole pitch and longer head can be manufactured by thermal micromachining processes. These processes are used to manufacture computer hard disc drive heads, inkjet printer heads, sensors, infrared images.

Explanation: The device consists of a glass chip that contains a single separation channel as well as an integrated conductivity detection cell. In contrast to most micro-fluidic glass devices, the channels are not wet etched in HF but machined by AJMM which allows the creation of micro-structures below 100μm, and additionally makes parallel holes machining at very low costs outside the clean room environment.
