tool dependency

image of tool dependency (to be added)

• types of machine tools capable of being build by concrete and floating precision (spindle requirements and any other precision parts listed) (manhy of the tool description are taken from wikipedia)

• lathe: a machine tool which rotates the workpiece on its axis to perform various operations such as cutting, sanding, knurling, drilling, or deformation with tools that are applied to the workpiece to create an object which has symmetry about an axis of rotation.
  • requires: a stiff spindle(roller bearings generally) with a chuck adapter on the end, 2 axis or movement, one long way and another about ¼ the length of the long axis, a tail stock with a morse taper, a quick change gear box for threading parts (only on manuals, hybride and cnc will use tachometer and servos to thread)
• Versamil attacment for lathe: a milling head attachment for the lathe with 2 axis of movement, a vertical linear travel (Y axis) and a rotary axis around the Y axis (B axis) plus a spindle with a quick attach plate for various attacment (milling, grinding, Gear cutting, off center drilling). this allows us to (much slower), create parts of this caliber [[1]]
  • requierments: a vertical axis (4 thinner ground ways mounted between plates), a motor mount with pulleys ending in a spine coupler capable of running 4 000 RPM),
• Centerless grinder: Centerless grinding is a method of material removal through grinding [[2]], similar to centered grinding except for the absence of the spindle. It has high throughput, i.e. a large number of parts can be manufactured in a short time.
  • requires: two accurate grinding spindles (4000 rpm and around 100rpm respectively), one of which should be able to rotate 10 degrees and travel to increase the diameter ground, and the ability to align both spindles and work blade along the same axis
• mill: A milling machine is a machine tool used to machine solid materials. Milling machines are often classed in two basic forms, horizontal and vertical, which refers to the orientation of the main spindle. Both types range in size from small, bench-mounted devices to room-sized machines. Unlike a drill press, which holds the workpiece stationary as the drill moves axially to penetrate the material, milling machines also move the workpiece radially against the rotating milling cutter, which cuts on its sides as well as its tip. Workpiece and cutter movement are precisely controlled to less than 0.001 in (0.025 mm), usually by means of precision ground slides and leadscrews or analogous technology. Milling machines may be manually operated, mechanically automated, or digitally automated via computer numerical control (CNC).
  • requires: three axes of linear travel (2:1:1 lengths) and a spindle, aditional axis can be added for more utility and easier use.
• surface grinder: Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or non metallic substance from a workpiece, making a face of it flat or smooth.
  • some of the work that a surface grinder would do can be done with a Milling machine that can run 4000 rpm but at lower accuracy
  • requires: three accurate axis, and a grinding spindle
• cylindrical grinder: The cylindrical grinder is a type of grinding machine used to shape the outside of an object. The cylindrical grinder can work on a variety of shapes, however the object must have a central axis of rotation. This includes but is not limited to such shapes as a cylinder, an ellipse, a cam, or a crankshaft
  • requires: 2 axis of linear movement, one turn table, and two spindles (one lathe, one grinding)
• drillpress
  • requires: quill (allows a spindle to move along its z axis while maintaining accuracy), and spindle. everything else is preference for moving tables and slides.
• bandsaw (vertical and horozontal): for cutting stock to size
  • requires: heavy hindge(horizontal) or linear (vertical), and hydraulic clamps (possible autofeed of stock)
• arbor press (hand or hydraulic): for seting parts on an arbor or broaching holes, etc
  • requires
