Machining Accuracy of Machine Tools
Technical Information Machining Accuracy of Machine Tools Productivity and accuracy of machine tools are important competition aspects. Rapidly changing operating conditions for machine tools, however, make it diffi cult to increase productivity and accuracy. In the manufacture of parts, increasingly small batch sizes have to be produced economically, and yet accurately. In the aerospace industry, maximum cutting capacity is needed for the roughing processes, whereas the subsequent fi nishing processes must be executed with maximum precision. For milling high-quality molds, high material removal rates are required during roughing and excellent surface quality must be obtained after fi nishing. At the same time, maximum contouring feed rates are necessary to realize the required minimum distances between the paths within acceptable machining times. Thermal accuracy of machine tools is becoming increasingly important considering the strongly varying operating conditions in manufacturing. Especially with small production batches that require constantly changing machining tasks, a thermally stable condition cannot be reached. At the same time, the accuracy of the fi rst workpiece is becoming very important for the profi tability of production orders. Constant changes between drilling, roughing and fi nishing operations contribute to the fl uctuations in the thermal condition of a machine tool. During the roughing operations, the milling rates increase to values above 80 %, whereas values below 10 % are reached during fi nishing operations. The increasingly high accelerations and feed rates cause heating of the recirculating ball screw in linear feed drives. Position measurement in the feed drives therefore plays a central role in stabilizing the thermal behavior of machine tools. -

Appendix D – Machining Guidelines
Appendix D – Machining Guidelines A. Holding and Chucking When holding any composite billet or part it is important to remember that, unlike metallic materials, polymers will deform/distort under excessive holding pressures. This is very important when machining parts/billets with a thin cross-section (0.250 in / 6.35 mm or under) and for finish machining. Parts/billets that are held too tightly may spring back after release from the holding mechanism and result in parts that are not concentric and/or undesirable dimensions. 1. Standard Jaw Chucking Four or six jaw chucks are acceptable for thick cross-section parts and billets. Ensure medium chucking jaw pressure to prevent material distortion. 2. Pie Jaw Chucking Pie jaw chucking, contacting as close to 90% of the OD as possible, is a superior holding method over standard jaw chucking. This works well for any operation and is preferred over standard chucking for finish machine operations. 3. Adhesive Bonding / Gluing As an alternate to standard chucking directly to the composite, a billet can be glued to a fixture of alternate material prior to machining operations. If this method is used, it is recommended that guidelines from the adhesive manufacturer be followed to ensure sufficient quantity and coverage. Both Loctite® 4090 and 3MTM Scotch-WeldTM Acrylic Adhesive 8405NS have been successfully used. 4. Holding Fixtures Use holding fixtures to grip composite components during finish machining operations. Holding fixtures shall contact 100%of either the OD or ID and should be a snug fit (in/out by hand). PTFE is the best material of construction for fixtures with PVC being a close (slightly more rigid) second choice. -

Molding & Machining: Metalwork in Geneva
MOLDING & MACHINING: METALWORK IN GENEVA This is a story of change. In the mid-1800s, Geneva claimed the most foundries in western New York State. The metal industry accounted for almost 70% of the city’s jobs in the 1950s and remained strong until the 1970s. Today, Geneva has only one major metal fabrication company. Geneva was not near iron ore or coal but 19th-century canals and railroads allowed access to raw materials. Demand for new products, from farm equipment to heating systems, allowed foundries to flourish. New factories changed Geneva’s landscape and affected its environment. Ultimately, 20th-century changes in technology and economics – and failure to adapt to change – caused most of the city’s metal industry to disappear. A foundry melts refined iron and pours it into molds to create cast iron. It is brittle but, unlike wrought iron pounded out by a blacksmith, objects can be mass produced in intricate shapes. Molding room at Phillips & Clark Stove Company Machining is the shaping of metal, and other materials, through turning, drilling, and milling. Machining tools were powered by steam engines in the 19th century and later by electricity. Machinists bent sheet metal to make cans, stamped metal for tableware, and milled stock to create machine components. Tool Room at Herendeen Manufacturing Company, 1907 This is a companion exhibit to Geneva’s Changing Landscapes in the next gallery, which has more information and artifacts about local industry. Support for this exhibit is provided by Rosalind Nester Heid in memory of her grandfather Samuel K. Nester, Sr. The First Geneva Foundries Refineries require iron, sand, water, fuel, and people. -

Initially developed to machine hard and tough materials for aircraft and rocket industry. Among electrical machining processes, ECM involves highest material removal. As in electroplating, ECM employs electrolytic principles to dissolve work material. Work materials must be electrical conductors. ECM is the reverse of electroplating. In electroplating, metal is deposited on workpiece, While in ECM, metal is removed from workpiece. ECM Process By Dr. Sunil Pathak 3 2. ELECTROLYSIS . Electroplating and ECM are based on Faraday’s Laws of Electrolysis: Amount of material produced in electrolysis is directly proportional to: a) Current flowing through - m α I m α It b) Duration of electrolysis - m α t c) Equivalent weight of deposited material - m α G . -

Monte Carlo Stock
Gun Stocks STOCK DESIGN AND STOCK STYLE Types of Gun Stocks A gunsmith requires a basic understanding of stock function prior to becoming a stock maker. A rifle stock, in function, is nothing more than a segment of wood, fiberglass, plastic, or other material shaped to support the rifle’s barrel and action. It also functions to conform to the shooter’s body so the shooter can control the firearm. That’s the mechanical side of it. However, arms lovers the world over consider a stock much more than a mechanical device. They think of a gun stock as a work of art and function (Figure 1). As a prospec- tive gunsmith, we hope this is your position. FIGURE 1—Notice the attractive oak-leaf pattern on this Bishop-III stock. (Photo courtesy of Reinhart Fajen, Inc.) Stocks can be built in a multitude of styles with a stock shape to fit everyone. Even factory rifles come in a wide variety of stock styles. Factory stocks, incidentally, have come a long way and can be considered quite good today, although cer- tainly not in the realm of a custom-made stock. Figure 2 shows a gun stock labeled with its proper nomenclature. 1 FIGURE 2—Become familiar with the names of the parts of a gun stock. Early Stock Design Turning the pages of gun history to an earlier time reveals that the first stocks well known to American shooters had a great deal to do with contemporary stock designs. However, such muzzleloader stocks left a lot to be desired.
