Basic Characteristics Of Am Technologies

Mixed model manufacturing is to make different anchors every day, according to the work orders and to avoid inventory accumulation. Mixed model manufacturing is also the ability to manufacture in small batches with a quick changeover from one anchor to the other (Russell & Taylor, 2011, p. 282). Albatross can accomplish the small batches but they need to have a faster turnaround time of 36 hours between anchor products.

An alternative to the fabrication process carried out by milling machines is something the author refers to as “additive fabrication” which he states is similar to the formation of Lego blocks (i.e., starting with nothing and adding materials to create an object). Gershenfeld states that the industrial automation company Festo utilizes additive fabrication in the composition of the products their machines create. However, Gershenfeld explains that milling machines and Festo are designed to be used by trained professionals and industrial engineers rather than the general public, conflicting with the idea of physical fabrication becoming accessible on a personal level. Gershenfeld states that individuals are limited to choosing from a menu of commodities preselected by other people. According to Gershenfeld, other possible means of personal fabrication are Micro-Electro Mechanical Systems (MEMS). MEMS fabrication consists of “cutting out tiny silicon machines with the fabrication processes that are currently used to make integrated circuits” (Gershenfeld

As a kid, i can remember always playing with the building blocks and thinking that i wanted to make things with my own hands that could make people’s lives easier. I took one step forward in pursuit of this dream by becoming a CNC machinist.

Woodturning is the action of shaping wood with a lathe (Webster’s). The lathe is a machine for turning, that is, for shaping articles of wood, metal, or other material, by causing them to revolve while acted upon by a cutting tool (Webster 's). While writing my research paper I will research many things such as: different types of woodturning, the education and training it takes to become a woodturner, the salary that one makes with this being a career, the pros and cons of being coming a woodturner, also the tools and techniques to using a lathe.

He argues that, while many processes were developed to improve metalworking after the war, the ones that ultimately prevailed were not the ones which were most efficient. He demonstrates how several alternate techniques actually had better results more quickly that the NC (Numeric Control) machining which eventually came to dominate the industries, and in fact the NC machines were often slower for a significant period of years.

“Precision metalworkers are among the most highly skilled production workers.” (Moore) They make tools, dies, and special guiding and holding devices for machines that mass produce products that are used daily like cell phones, appliances, and heavy equipment. Tool makers create tools to shape, cut, and form metal and other materials. They also make devices that hold metal while it is being drilled or stamped. Gauges are also make by Tool

The first process examined uses the Lablond Lathe machinery and requires a machined diameter of 7.7250, plus tight tolerances of + .0005 inches. A Process Capability Ratio (Cpk) analysis of the lathe’s data, results in a Cpk of .379 (exhibit A). A result of less than one indicates the machine is not capable of matching the tolerances laid out in the IMS spec. Therefore the Lablond Lathe is not suitable to handle the process it is being used for. Before a more suitable machine is selected, the Lablond Lathe should be checked for calibration, as should the measuring equipment used. If all fall within calibration specs, new

NC Machining is a process used in the manufacturing sector that involves the use of computers to control machine tools. Tools that can be controlled in this manner include lathes, mills, routers and grinders. The CNC in CNC Machining stands for Computer Numerical Control. On the surface, it may look like a normal PC controls the machines, but the computer's unique software and control console are what really sets the system apart for use in CNC machining. Under CNC Machining, machine tools function through numerical control. A computer program is customized for an object and the machines are programmed with CNC machining language (called G-code) that essentially controls all features like feed rate, coordination, location

What really makes AM technology appealing to manufacturers like GE Aviation is the ability to design parts without being limited by traditional manufacturing methods. The CAD computer allows the engineers to design with intent and embed cooling structures or lubrication joints into a part; which was not previously feasible with traditional manufacturing. Engineers can also

The benefit that machine provides is called a mechanical advantage. Its amount is defined by actual mechanical advantage (AMA, includes force of friction). There is also an ideal mechanical advantage (IMA) but it does not take in account the force of friction which is inevitable in our world.

Additive Manufacturing(AM) is a manufacturing technology that creates objects rapidly with the help of Computer Aided Design (CAD) files. Different from traditional manufacturing method, additive manufactured models are usually stacked out by a serial of planer slices which are produced by processing wanted CAD designs with mathematical code.

Part geometries can have a great deal of impact depending upon the type of moulding used. Some work well with automation typical for horizontal LSR moulding, while others work better for the manual operation of vertical machine moulding. Also, the complexity of the geometry plays a role in governing the size of the mould and thus the size of the moulding machine.

The components of preassembly may be completed at the job site eg specialized factory, in a remote location other than the place of final installation. Usually preassembly often contains portions of systems, and work that is from a variety of crafts is naturally necessary for the installation. It is considered to be a combination of prefabrication and modularisation and may make use of fabricated components completed off-site and then assembled near the site. These units can then be installed, similar to modules (on site). (Klerk, 2013)

CNC Vertical End Milling Machining is a widely accepted material removal process used to manufacture components with complicated shapes and profiles. During the End milling process, the material is removed by the end mill cutter. The quality of the surface plays a very important role in the performance of milling as a good-quality milled surface significantly improves fatigue strength, corrosion resistance, or creep life. The surface generated during milling is affected by different factors such as vibration, spindle run–out, temperature, tool geometry, feed, cross-feed, tool path and other parameters. During finish milling, the depth of cut is small. The most important interactions, that effect surface roughness of machined surfaces, are between the cutting feed and depth of cut, and between cutting feed and spindle speed. Surface Roughness is affected negatively if the applied force is increased. Surface roughness at the same feed rate becomes higher when a small nose radius is used. Technological parameter range plays a very important role on surface roughness. There is a need of a tool that should allow the evaluation of the surface roughness before the machining of the part and which, at the same time, can easily be used in the production-floor environment contributing to the minimization of
