  Induvidual assignment

  This week the induvidual assingment was to make something big design, mill and assemble.
  I started by designing a chair in Fusion, i have before in week 2 document how i did use Fusion designing things and export the sketch in to DXF file then import that DXF in to inkscape and then make the cuting file from that so im not going to do that again here.
  But new in this week is a program called vcarf that is the program we use to make the file ready to cut in the shopboot mill.
  Here is the documentasion of how i used the Vcarf and the shopboot mill it self*

  ## Grupp assignment
  

  This week grupp assignment is to complete the safety training in the lab. test the mill ruout, alignment, fixturing, speeds, feeds, materials and toolpaths and document in grupp page and reflect in the induvidual site.

  Safety training

  In Fablab reykjavik we are four students, one day wi did gather in the lab and did go over the safety instruction for our Lab
  There are allways few thing we need to be aware off

  1. Were eye protection  
  2. Were ear protectjon  
  3. Always protect long hair by having hair net or pull it back  
  4. No open shoes, always were close shoes; (here im little troubled caus i have been alot around big machinses in my lifetime then we always were safety shoes with hard to like steel or kevlar, and i think it should be used all time around this machine were you are working with heavy material and tools)  
  5. NO loose clhoting(always make sure your clohts are tide and can not be grabed by the machine)  
  6. Keep hands away always, if needed to bring your hands near the machin make sure the machin si stopp and cannot be started by taking out the safty key  
  7. Were safety gloves. **ONLY WHEN MOVING PLATES NOT WHEN WORKING ON THE MACHINE**
  

  Then after we did go over this few points our instructor Andri Sæmundsson showed us how the machine works, He did show os how to setup the machin in the computer how to preaper the file for cuting, how to change the mill bits how to zero all the axis how to start up the machine and the vacum. how to and how importand it is to make sure the wood you working with is stuck on the machine, how importand is to make sure that nails and screws wont get in conntact whil the mill bits and if that happens then we need to check out the vacum to make sure no sparks have go in there as the materila in the vacum bag is highly flamable and could be to a big fire in seconds. He did also explane why it´s important to make sure the bit sit stuck in it´s place. The biggest danger in the prossess of using this machine is fire cause we are working with highly flammable material and heat so it´s not hard to get fire if we are not carefull.
  Other danger is moving parts that can easily grab things like hair, cloths and gloves and cause serious injury or death, so always be carfull around the machine never work on it while:

  1. Tierd  
  2. Alone in the lab  
  3. Never leave the machine unattended  
  4. Always use the vacuum
