Question 3: a) What is the main use of stepper motors? In essence, stepper motors are applied in motion-control positioning system. For instance in 3D printers, disk drives, intelligent lighting, scanners, CNC machines, printers, camera lenses, plotters and slot machines. b) What are the similarities and differences between a reluctance, a permanent magnet and hybrid stepper motors? The three motors are similar in that, they all have power electronic control that comes with electronic…

1.0 Introduction: Digital Painting is a method of creating an art object (painting) digitally and/or a technique for making digital art in the computer. It adapts traditional painting mediums such as acrylic paint, oils, ink, watercolor, and so on. As a technique, it refers to a computer graphics software program that uses a virtual canvas and virtual painting box of brushes, colors and other supplies. The virtualbox contains many instruments that do not exist in the world, and which give a…

3.2 Analysis of chip formation Fig. 7 shows the chip forms obtained during milling of the Al7075 (a) and MMCs (b) using the uncoated carbide inserts at a feed rate of 0.1 mm/tooth, machining speed of 290 m/min and axial depth of cut of 1.3 mm. The Al7075 chips formed during milling exhibited a smooth and shiny surface, and were in a semicircular and parabolic trapezoidal wave with a small radius and a saw-tooth-form, as shown in Fig. 7 (a). Fig. 7 (b) shows the chip shapes formed during the…

Ability to view the surrounding lanscape; provide design and construction consultation  Allow visual examination of alternative project options; animation of vehicle movements and driving simulation.  The developed 3D modes can be used for consultation with local…

Chapter-4 (Introduction to FEM Analysis using COMSOL MULTIPHYSICS) 4.1 Introduction: In simplest form we can define Micro Electro Mechanical Systems (MEMS) as miniaturized electro-mechanical devices made by using various techniques of micro-fabrication, where the dimensions can be in the range from less than one micron to several millimeters. Many MEMS devices are of the size of a grain or the eye of a needle. MEMS is indeed one of the most promising and emerging areas of engineering. This…

odor causing microbes. Solar panels have almost 20 grams of silver in each panel! Creating a higher demand on silver in the solar panel industry. Three dimensional printing is by far the most high-tech thing that scientist have created, but did you know that silver played a part in making it all happen? Three dimensional printing ink is made out of silver nanoparticles, generating a higher demand for silver. Silverware is big user of silver as well. Along with gold and diamonds, silver is…

Why Vinyl Is A Good Choice In Replacement Siding If your old aluminum siding is dented, chalky, and worn out, then you may want to replace it with vinyl. Vinyl siding is getting more and more popular because it has advantages over other options like aluminum. Here are some of the benefits of putting new vinyl siding on your home. Vinyl Doesn't Get Chalky One of the drawbacks of aluminum siding is that it gets chalky as the metal oxidizes. Vinyl doesn't have this problem. The appearance of…

The typeface I am picking is the Arial font. The Arial typeface was drawn in 1982 by designer Robin Nicholas and Patricia Saunders. It was original called Sonoran Sans Serif and was renamed Arial in 1992. Arial was made similar to the Helvetica font design, some say copying it for thickness and height. It started off as a bitmap font. The bitmap were high-resolution laser comp fonts that were used as a starting point to sample down give it a 240dpi or 300dpi font. Arial was original…

Locking mechanism The joints had to be such that they can be loosened and tightened at any required configuration, this obstacle was overcome by the use of wing nut at the end of the screw instead of a normal nut, and the image below shows the wing nut and bolt. This is the most cost effective yet strong way of locking the joints compared to knobs and other clamp mechanisms. Materials For the Robot Arm Construction our group members had a variety of materials to choose from, these materials…

When you buy a new toy or piece of furniture, the process of creating and producing the item is longer than you may think. From sketching to making a three dimensional layout on the computer, industrial designers use many diverse skills to create everyday products. As mentioned in the skills and abilities section of O*NET OnLine, industrial designers “develop and design manufactured products, such as cars, home appliances, and children's toys. Combine artistic talent with research on product use…
