Cutting-tool fabrication

Two maj or areas of application of CVD have rapidly developed in the last twenty years or so, namely in the semiconductor industry and in the so-called metallurgical-coating industry which includes cutting-tool fabrication. CVD technology isparticularly important in the production of semiconductors and related electronic components. Itisby far the most... 

The tips used for STM experiments should be sharp and stable. Chemical stability can be achieved by using a noble metal. Mechanical rigidity can be reached by short wires. Alloys of Pt and Ir are frequently used for fabrication of STM tips. They can be produced in a surprisingly simple way just by cutting a metal wire with conventional cutting tools. Because of their high chemical stability, such Pt/Ir tips are well... 

Chemical vapor deposition (CVD) has grown very rapidly in the last twenty years and applications of this fabrication process are now key elements in many industrial products, such as semiconductors, optoelectronics, optics, cutting tools, refractory fibers, filters and many others. CVD is no longer a laboratory curiosity but a maj or technology on par with other maj or technological disciplines such as electrodeposition, powder metallurgy, or conventional ceramic processing. 

Use bench welding whenever possible (automatic). Field welding (manual) shall be kept to a minimum. Hand welding will be permitted only with approval on a case-by-case level. Do not use ferrous material, tools, or equipment (carbon steel cutting tools) in the fabrication or installation of systems. 

When processing plastics some type of tooling is usually required. Tools include molds, dies, mandrels, jigs, fixtures, punch dies, perforated forms, etc. The terms for tools are virtually synonymous in the sense that they have some type of female and/or negative cavity into or through which a molten plastic moves usually under heat and pressure or they are used in secondary operations such as cutting dies, stamping sheet dies, etc. These tools fabricate or shape products. In this chapter injection molds and extrusion dies are primarily reviewed because they represent over 95% of all tools made for the plastic industry. This chapter also includes information applicable to other molds and dies used in the other processes some of the other chapters too provide information applicable to their tools. 

The ternary B-C-Ti system was intensively studied by Rudy et al. [99] and has been considered for the fabrication of ceramic cutting tools [100-103], The most recent critical assessment was published by Duschanek et al. [104, 105] who, in contrast to the previous authors, take the re-established Ti3B4 phase into account. No ternary phases have been discovered. The ternary solid solubility of the particular binary compounds except TiCogiBo n is generally less than 1 at.-%. TiB2 coexists with...

SiC whisker reinforced alumina has significantly improved mechanical properties compared to monolithic alumina ceramics. The composites can be fabricated by several methods using typical conventional powder processing techniques. Cutting tools are the main application for the composites at the present time. 

Die Cutting (Punching) Die cutting of doublesided adhesive tapes becomes tricky for channel dimensions below 1 mm. The dimensional limitations are caused by the fabrication and wear of the die cutting tools as well as by the cutting edge quality obtainable for delicate microstructures. 

Routing Files. Router files and the respective router cutting tools have to be archived and available for download to the appropriate routing machine when production needs them. Router tool preparation precedes the actual routing or secondary drUhng operation in order to create the final fabrication cassette.
