Week7 computer-controlled machining (Mar 9)

  • Assignment
  • 1.make something big.

    2.Fabricate a chair.

  • Necessary
  • 1.CNC Router VR1212B

    2.Type3 software

    3.Newvic CNC System

    4.CorelDRAW X4

    5.Curve sawing/Sanding paper.

    6.Veneer plywood

  • Overview
  • 1.Tools and Materials

    2.Speeds and Feeds:

    Chip load: ~ 0.001-0.010" = feed rate (inches per minute) / (RPM x number of flutes)

    Cut depth: ~ tool diameter

    Step-over: ~ tool diameter/2

  • The plan:
  • 01
  • How to make the chair.
  • Describe my design on the paper.

    Use the AutoCAD and CorelDRAW X4 to make the Design.

    Test and make a small one.

    02 03
  • CNC cutter
  • Select the material and tool.

    04

    Set the parameter and figure the path.we can import the file into the type3 and get into the CAM modules. if you have added the tool, you can creat the path and set the 2D cutting parameters about cut depth and step-over. And then you can sumulate the path and export gcode file.

    Adjusting Tool and set the origin point.

    13
