 the turning operations is done until the diameter of the cylindrical object is 19mm and then, the facing for the work piece .  Step turning is done in the right side end. The length of the step turning is 30mm and the diameter of it is 16mm.  Tapering is done by changing the angle of the tool and its done till the next 30mm from the step turning.  Chamfering is done at both ends of the work piece.  Knurling is now done at the left side of the work piece and the operation is done up to a length of 40mm.  Threading is then done to the work piece by an automatic feed shaft .  The pitch of the threading is given as 2mm. The threading is done for the right side 30mm. [b] Since the work piece is not in a cylindrical object and is having holes in it, the process is to be done in a milling machine and the drilling machine is also used in manufacturing the given component.  A work piece of size 90*65*12 is required for manufacturing the …show more content…

Because it shouldn’t break during the operation. When the material is cast iron then the tool should be even stronger than the material. For cast iron, a single point cutting tool of high speed steel and carbon steels should be used for this. There are cutting tools that are even stronger and powerful but the purpose of those is to cut even stronger materials. So in Cast iron, carbon steel and high speed steels are the perfect tools for the purpose of facing and turning operations. material Specific features Galvanized iron Sheet metal Slabs of galvanised iron are pushed into the rollers and made to pass through them Rollers made up of grey iron is mostly used for rolling process. High amount of load acting on the material which is at its recrystallization point tends to deform and then sheet metal is formed. Grey cast iron is used and it is considerably harder as it has some graphite content in its mixture which makes it hard. material Specific features iron Surface grinding Cubic boron nitrate and diamond is used and in conventional- silicon carbide, ceramic grains or aluminium oxide is used. Since iron comes under the conventional grinding, grinding wheels that are made of silicon carbide, ceramic grains or aluminium oxide could be

Hey my name is Keith Starks and I want to start talking about how LED Pendulum Metronome started from and the founder of LED Pendulum Metronome. In 1696 Etienne Louie first successfully used an adjustable pendulum in the construction of the first mechanical metronome. Also his design did not make any sound and did not include an escapement with which to keep the pendulum in motion. And I think In order to get the correct pulse with this kind of visual devices, the person that working on it needs to watch the precise moment where the pendulum is exactly vertical. Also as the left and right positions are constantly changing due to the decreasing amplitude.

o Would it be useful to identify the core issue of the risk being addressed? In the month of July, 4 teams noted inability to safely evacuate from the home. Although this is risk, it is unclear why. If teams were to implement the 5 why’s, could they drill down to the core issue. For example, if the inability to evacuate was due to mobility, could we identify DME to mitigate that risk.

NOT function is a logical function in Excel. It returns the opposite value of a given logical value in the formula. This function helps to check that one value is equal to another value or not. If we put TRUE in this function it returns False, it we put False then it returns True. We can use either TRUE or FLASE value in this function at a time.

According to the accounts provided by Hamilton and Biggart (1988), by Biggart (1991), and/or by Saxenian (2011), compare the impact of two or more of the following influences on the economies of one or more East Asian countries: institutions; networks; markets; transaction costs. The Asian Miracle Since WWII, East Asian countries have undergone drastic changes in their economic infrastructure. Even though WWII left this region war torn, countries such as Taiwan and Japan have become an “Asian Miracle” as they rapidly developed despite their predicament.

3.4 Displaying meaningful results Plotting points on a graph for analysis becomes difficult when dealing with extremely large amounts of information or a variety of categories of information. For example, imagine you have 10 billion rows of retail SKU data that you are trying to compare. The user trying to view 10 billion plots on the screen will have a hard time seeing so many data points. One way to resolve this is to cluster data into a higher-level view where smaller groups of data become visible. By grouping the data together, or “binning,” you can more effectively visualize the data.

1) A brief outline of the following: • Threaded shaft: The secondary technique that is used here is called turning, meaning this is created using the Lathe to make shapes to the desired lengths and diameters, producing different shapes and sizes. Meaning when we needed to create a thread we used the centre lathe to do the job much more accurately and faster. Forming parts that have a cylindrical or conical shape or to cut threads. With special attachments, a lathe may also be used to produce flat surfaces, as a milling machine does.

Pipe welding. There are multiple factors to consider when welding pipe. From the type of metal and filler to be used, to cover gasses, such as argon and carbon dioxide, to prevent welds from being contaminated, or the proper angles to bevel pipe coupons, a welder must know it all. Metallic pipe has been manufactured using several processes throughout history and has been vastly improved throughout the centuries. The processes used to fabricate piping systems have also been greatly improved.

Efficient mowing with zero turn mower reviews Keeping your lawn nice and trim is something that everyone wants but is quite a difficult challenge to complete. Lawns need to be well trimmed to prevent the growth of wild plants which would in turn affect the grass itself, also, it helps prevent the blades from growing too much and provides a comfortable feel to walk on and therefore needs to be maintained well. To do so requires the use of the right equipment which in this case is the lawnmower and if in case you live in a place with a narrow yard, you need a special kind of mower. For this reason, there are zero turn mower reviews which help the customer in better understanding the way things work and what kind of lawnmower is best for them

1- The electromagnetic spectrum is the range of all type of EM radiation. It also describes the wavelength of light. EM radiation is the radiant energy that is released by a certain electromagnetic processes and a wavelength is the distance between successive crests of a wave. 2- The different between ionising and non-ionising radiation is that ionising radiation carries energy to ionize atoms and has more energy than non-ionising.

The day before the Regatta Hobart, Australia A young man of near eighteen years old walked out of his bedroom of the apartment that accommodated him alone and waltzed progressively across his lounge room carpet to an antique gramophone wearing only what he had worn when he came into this world. He lifted the needle and placed on a record that he had slipped from its cover. Replacing the needle, he rotated the handle for the turntable to spin.
