2011 SkillsUSA Washington Precision Machining Contest

April 22, 2011, Washington State SkillsUSA Precision Machining Contest Every effort was made to include every contestant and every judge in this video. Hopefully, they are all there. (My sincere apologies if any are missing.) The contest was held at Perry Technical Institute, Yakima, WA. Contest hosts were Machine Technology Department Head Dan Steinmetz and Machine Technology Instructor Jason Wellner. Gold Medalist: Caleb Franett from Sno-Isle Skills Center and Arlington High School. Silver Medalist: Dylan Dunham from Sno-Isle Skills Center and Lake Stevens High School. Bronze Medalist: Thomas Williams from Port Angeles High School. Sno-Isle Skills Center Instructor: Tom Clemans Port Angeles Instructor: Mike Frick The precision machining contest is based on NIMS (National Institute for Metalworking Skills) standards for machining and manufacturing, and is a very rigorous contest. On Friday of conference week, the participants go through five 1-hour contest stations. The five stations are: . Manual milling machine . Engine lathe (manual turning machine) . Semi-precision layout and drill press . Quality control, workpiece inspection, blueprint interpretation . Machining theory written test For each section in which a machined part is made, points are awarded for each correct dimension. A part need not be completed in order to have one or more dimensions within the specified dimension tolerance. The allowed size tolerance for many of the dimensions is ± .005 (5/1000) inch <b>...</b>

Impeller machining on five axis Starrag machiningcenter

The efficiency of radial compressor wheels depends to a high degree on the precision of the production process. This is something to which we are well suited as a worldwide recognised specialist in the field of 5D milling technology, as high-precision machining of impellers has been one of the specialist areas of Starrag for many years. With the STC 100 we have set another milestone.

Cylinder Block Machining Video - Engine Building DVD

Buy the "Basic Engine Building" DVD store.boxwrench.net Basic Engine Building DVD - Chapter 25: Cylinder Block By this time your block is disassembled and in the machine shop. One of the most informative sections, here we take you behind the scenes to show what goes on while your away. We show the process of align honing the main bearing bore that is needed before anything else can be machined. Then the block deck is leveled and machined as needed for the new head gaskets to seat properly. And finally the cylinder walls are bored out just shy of their new size, which will be achieved when they're honed.BoxWrench.net is a community and resource designed for automotive enthusiasts. The Basic Engine Building DVD is over three hours of engine building that covers everything from removal and disassembly to final assembly and engine start-up. This is the ultimate DVD for any home mechanic or engine enthusiast that wants to see a complete rebuild from Teardown to Start-Up. This video can be used to learn how to work on almost any type of internal combustion engine including V8, V6, Straight 8, in-line 6 and even 4 cylinder engines. All of the interactive features and menus will not work over YouTube. This video is great for people interested in car repair, car care, and restoration. As well as hot rods, muscle cars, performance parts, and boosting horsepower. It can also help you to gain knowledge for increasing fuel economy, how to lower your emissions, and covers preventative <b>...</b>

Mini Machining Center - final design 4th axis - scratch built servo powered

PLEASE NOTE this is an early prototype. see the current model here: www.youtube.com X2 mill with final design scratch built 4th axis doing multiple operations with one G-code program. 4th axis has sealed ball bearings pre-loaded by threaded collar and homing index moved to the rear and a robust motor mount. A new Rutex 2010 servo drive gets full speed and power from the motor, allowing use of a carbide insert with chip breaker . . no more long stringies! Speed is 400000 quadrature counts per sec, which is 3300 motor RPM. Spindle can run 2:1 or 3:1 (as shown) ratio. First pas is .062" or 1/8" off stock OD. Tested depth of cut (so far) is .080" aluminum and .060 Steel, limited by rigidity of the little mill. Part is a vacuum fitting for classic Corvette (GM Crossfire injection). Also still testing Youtube HD. This upload file is H.264 1080P 30fps. File size just under 1GB.

Knifemaking Tuesdays Week 01 - designing and machining the first test blades

I'm taking 1 day a week to focus on my new custom knives, very exciting! Today's project was to figure out how to fully machine a knife blade so that it doesn't have to spend any time on a belt grinder. I made 4 different designs and after a lot of practice I finally figured out how to render a blade profile in Solidworks, now that I have that skill I can design pretty much any shape! This video goes through some of the design process as well as the machining of these 4 little blades.
