  1. 1. By Katie Danilowicz
  2. 2. Introduction/Contents <ul><li>Without Math you can’t have DT. This statement may sound a bit strange, but it’s actually true. Anyone who takes DT will tell you. I’ll show you how it’s true in the presentation. I’ll mainly talk about a few machines and their relation to math. Then at the end I’ll show you some other bits of how DT is like math. The machines I will talk about are: </li></ul><ul><li>Lathes </li></ul><ul><li>Drills </li></ul><ul><li>Band Saws </li></ul>
  3. 3. Lathe <ul><li>A lathe is a machine that makes circular shapes out of wood. All lathes have a horizontal beam which is the bed. At the end of the bed is the headstock which rotates with the wood on a horizontal axle with an axis spinning parallel to the bed. The products that lathes make are circular figures. This machine spins the block to cut, sand, knurl, or drill with tools. The product has symmetry about an axis of rotation. </li></ul>
  4. 4. Extra Pictures: Using a Lathe
  5. 5. Inside of a Band Saw <ul><li>Inside the band saw are two circles that both spin 360 degrees. While they both spin the blade of the band saw only touches 180 degrees of each circle making it go in one direction to cut the wood. For the people who make the blade they get the distance between both of the circles multiply by two and add the circumference of one of the circles to see how long the blade should be. </li></ul>
  6. 6. Extra Pictures: Band Saw
  7. 7. Drills <ul><li>Drills have circular gears inside of them to make the chuck (the part that the drill bit attaches to) spin. To this you add the drill bits that have cylindrical spirals cut into them. They spin on an axis of rotation. The spiral helps it act as a inclined plane. </li></ul>This is a normal drill. The black circular part is called the chuck. The silver part attached to it is the part where you attach the drill bit.
  8. 8. Extra Pictures: Drill
  9. 9. How This All Relates to Math <ul><li>In this you (hopefully, some of you might already know from DT class) learned DT relates to math from each slide. And really, DT and Math go hand in hand. There are tons of measurements you have to do to make your product. You have to look at angles to connect pieces. Also there is the scroll saw, which makes circular or round shaped projects. You drill a hole in the middle of the wood, then put the blade through the hole and rotate the wood with your hands to cut the wood the way you want it to look like. Then there are the circles that make the machines work. </li></ul>
  10. 10. Lathe Interactive Activity <ul><li>http://www.fi.uu.nl/toepassingen/00182/toepassing_wisweb.en.html </li></ul><ul><li>This website is to help plan you project and what it should look like when you are finished. It is a lathe which is the first machine I talked about. </li></ul><ul><li>To use this you click the little white box in the bottom left hand corner and the click a different white box, until you get the shape. </li></ul>

Bibliogrpahy <ul><li>http://en.wikipedia.org/wiki/Lathe </li></ul><ul><li>http://www.centurymachinery.com/images/7063-Z-2_doAll%20vertical%20band%20saw_model%206013-H_capacity%20throat%2060%20inch_height%20under%20guide%2013%20inch_vari%20blade%20speed%2040-10800%20fpm_hydraulic%20feed%20tilt%20table_rise%20fall%20fall%20guide%20post_Drive%20Wheels%20Doors%20Open.jpg </li></ul><ul><li>http://www.archithings.com/wp-content/uploads/2009/04/dewalt-xrp-and-xrp-lithium-ion-drills-588x588.jpg </li></ul><ul><li>http://www.mfg.mtu.edu/cyberman/machining/trad/turning/lathe.jpg </li></ul><ul><li>Mr. Haque was also a huge help with this project. Because I was in DT class, I didn’t have to do much research on how the machines work, except on the Lathe which I have only used once. http://www.fi.uu.nl/toepassingen/00182/toepassing_wisweb.en.html </li></ul>
