Numerical Control (NC) Fundamentals
Lab Sheet for CNC Laboratory Department of Production Engineering and Metallurgy Prepared by: Dr. Laith Abdullah Mohammed Production Engineering – CNC Lab Lab Sheet Numerical Control (NC) Fundamentals What is Numerical Control (NC)? Form of programmable automation in which the processing equipment (e.g., machine tool) is controlled by coded instructions using numbers, letter and symbols - Numbers form a set of instructions (or NC program) designed for a particular part. - Allows new programs on same machined for different parts. - Most important function of an NC system is positioning (tool and/or work piece). When is it appropriate to use NC? 1. Parts from similar raw material, in variety of sizes, and/or complex geometries. 2. Low-to-medium part quantity production. 3. Similar processing operations & sequences among work pieces. 4. Frequent changeover of machine for different part numbers. 5. Meet tight tolerance requirements (compared to similar conventional machine tools). Advantages of NC over conventional systems: Flexibility with accuracy, repeatability, reduced scrap, high production rates, good quality. Reduced tooling costs. Easy machine adjustments. More operations per setup, less lead time, accommodate design change, reduced inventory. Rapid programming and program recall, less paperwork. Faster prototype production. Less-skilled operator, multi-work possible. Limitations of NC: · Relatively high initial cost of equipment. · Need for part programming. · Special maintenance requirements. · More costly breakdowns.

Smiths Abound Discussion Document
Smiths Abound According to Wikipedia, Smith is the most common surname in the United Kingdom, Australia and the United States, and second only to Li in Canada. It is the fifth most common surname in Ireland. Worldwide there are about 5 million Smiths; data on how many live in the U.S.is conflicting, but at least 2.4 million. Therefore, it’s not surprising that people who bear the surname Smith have chosen to have their own holiday on January 6. The event seems to have been started by Adrienne Sioux Koopersmith in 1995, in part to find help in tracing her own genealogy. She chose January 6th because it was the birthday in 1580 of Captain John Smith, the English colonial leader who helped to settle Jamestown, Virginia in 1607, thereby bringing the name to North American shores. The word “smith” derives from the word “smite” or “strike,” and although there has been a suggestion that Smiths originally derived their name from the occupation of soldiers (smiting the enemy), most present day Smiths are probably descendants of blacksmiths who worked with black metals, such as iron. Related names include: • Whitesmith and Tinsmith for those who worked with tin • Coppersmith (or in Adrienne’s case) Koopersmith for those who worked with copper, and Brownsmith, Redsmith, and Greensmith for the color of copper when it oxidized • Silversmith and Goldsmith, obviously for those who worked with silver and gold In addition, of course, there are people named Smythe, Smithers, Smitherman, Smithson, or Smithwick, all related in one way or another to their laboring ancestors. -
The Rogues Proposal Free
FREE THE ROGUES PROPOSAL PDF Jennifer Haymore | 416 pages | 19 Nov 2013 | Little, Brown & Company | 9781455523375 | English | New York, United States Rogues (comics) - Wikipedia This loose criminal The Rogues Proposal refer to themselves as the Roguesdisdaining the use of The Rogues Proposal term "supervillain" or "supercriminal". The Rogues, compared to similar collections of supervillains in the DC Universeare an unusually social group, maintaining a code of The Rogues Proposal as The Rogues Proposal as high standards for acceptance. No Rogue may inherit another Rogue's identity a "legacy" villain, for example while the original still lives. Also, simply acquiring a former Rogue's costume, gear, or abilities is not sufficient to become a Rogue, even if the previous Rogue is already dead. The Rogues Proposal do not kill anyone unless it is absolutely necessary. Additionally, the Rogues refrain from drug usage. Although they tend to lack the wider name recognition of the villains who oppose Batman and Supermanthe enemies of the Flash form a distinctive rogues gallery through their unique blend of colorful costumes, diverse powers, and unusual abilities. They lack any one defining element or theme between them, and have no significant ambitions in their criminal enterprises beyond relatively petty robberies. The Rogues are referenced by Barry Allen to have previously been defeated by him and disbanded. A year prior, Captain Cold, Heat Wave, the Mirror Master Sam Scudder againand the Weather Wizard underwent a procedure at an unknown facility that would merge them with their weapons, giving them superpowers. The procedure went awry and exploded. Cold's sister Lisa, who was also at the facility, was caught in the explosion. -

MABA Newsletter Index January 1980 thru December 2020 This searchable index will help you locate what year & issue projects and information have been published in the MABA newsletter, The Upsetter, over the past 40 years. It is divided into 37 categories to help you quickly narrow your search or use the PDF “Find” function. Sometimes an article fits into more than one category so it has been placed under the most obvious location, while occasionally being placed under multiple categories. The demonstrator, not necessarily the author of the article, is listed to identify and/or credit the source of the information. Please forward any comments or corrections to the MABA newsletter editors. Dates of newsletters that were not available for inclusion in this index: May – June 1995; November – December 1995; If anyone has copies of these newsletters and could pass on the contents so they can be added to this index, it would be greatly appreciated. Look over the entire index and note the categories that have a lot of entries, and those that have only a few. Have you been to a demonstration; solved a problem; completed a project; made a jig, fixture or tool that you’d want to share with others? Would a write-up help other smiths get their projects done without going through the problems you’ve had? Where do your blacksmithing interests lie? Are there many entries in your area of interest? Would an article about your area of interest create some excitement about the subject? Please consider contributing an article to the Upsetter and passing along your experience and information to the MABA membership. -

Report Documentation Page Information
Report Documentation Page Information Title and Subtitle: AISI/DOE Technology Roadmap Program TRP 9742: Removal of Residual Elements in the Steel Ladle by a Combination of Top Slag and Deep Injection Practice Authors: S. Street, K. S. Coley and G. A. Iron Performing Organization McMaster University Department of Materials Science and Engineering 1280 Main Street Hamilton, Ontario L8S 4L7 Canada Abstract The objective of this work was to determine if tin could be removed from liquid steel by a combination of deep injection of calcium and a reducing top-slag practice. Calcium forms an intermetallic with tin, CazSn, but it is much less stable than CaO or Cas. The premise of the proposal was that the intermetallic could be formed during deep injection, and prevented from rapidly reverting to the steel by maintaining reducing conditions in the top slag. The work consisted of three types of experiments: 1. Injection of calcium wire into 35-kg heats melted in an induction furnace to study the kinetics of tin removal under various conditions of temperature, oxygen activity and sulphur content. 2. A program to study the solubility tin in the slag as a function of oxygen potential, temperature and slag composition. 3. Two full-scale plant trials were carried out at Dofasco Inc. as a result of the promising results from the laboratory studies. In the injection into the induction furnace, it was found that 7 to 50% of the tin was removed from initial tin contents of 0.1% Sn, using 8 to 16 kg calciudtonne steel. The extent of tin removal was found to increase with greater calcium injection, lower oxygen activity in the steel and lower temperature. -
