Turning GENERAL TURNING Steel‚ cast steel‚ long chipping malleable iron. Basic grades CT5005 (HT) – P05 (P01 — P10) An uncoated titanium-based cemented carbide – a cermet. This grade is designed to give maximum performance in super-finishing of steel and cast-iron when exceptional surface finish is required. GC4005 (HC) – P05 (P01 — P15) A CVD-coated grade with excellent resistance to crater wear and plastic deformation. A very good choice when machining dry‚ long engagement times

Single point cutting tools: Nearly all turning processes use single point cutting tools‚ this is‚ and tools that cut with only a single edge in contest with the work. Most turning is done with coated index able carbide inserts‚ but the tool material may also be high-speed steel‚ brazed carbide‚ ceramic‚ cubic boron nitride‚ or polycrystalline diamond. 75 percent of turning operations use just a few basic tool geometries. When tool holder itself rather than the actual insert. However‚ let’s first focus

Date: 09-02-2013 Experiment 1(a) Laboratory determination of water (moisture) content of a soil sample by oven drying method Reference: ASTM D2216-98 Need and scope of the experiment: In almost all soil tests natural moisture content of the soil is to be determined. The knowledge of the natural moisture content is essential in all studies of soil mechanics. To sight a few‚ natural moisture content is used in determining the bearing capacity and settlement. The natural moisture content will

At 1970s‚ the public health infrastructure‚ sewage and waste system in Bhopal are still in very poor condition . Besides‚ mass casualty emergency response system also lacking in Bhopal. Union Carbide Corporation is one of the largest chemical and polymer companies in the united state. In 1984‚ Union Carbide operated in 37 host country as well as in its home country‚ ranking 35th in size among United State . The history of the company in India goes back much further that‚ to the early 20th century

Just after midnight on December 3‚ 1984‚ a pesticide plant in Bhopal‚ India had a chemical leak accident. The chemical that was released into the air is called methyl isocyanate‚ or MIC‚ used to make pesticides. This chemical is tremendously harmful and fatal to humans‚ livestock‚ and crops. Only a short-term exposure may cause death or unfavorable health effects. The slums of Bhopal and its residents that surrounded the plant which were mostly affected by the gas suffered dearly. An estimated 8

parts: high speed steel‚ cemented carbide‚ and ceramic. For the high speed steel tool‚ the Taylor equation parameters are: n = 0.125 and C = 70 (m/min). The price of the HSS tool is $15.00 and it is estimated that it can be ground and reground 15 times at a cost of $1.50 per grind. Tool change time is 3 min. Both carbide and ceramic tools are in insert form and can be held in the same mechanical tool holder. The Taylor equation parameters for the cemented carbide are: n = 0.25 and C = 500 (m/min);
