CAM Files Protocol

Computer Aided Manufacturing (CAM) files are toolpath files that enable a computer-controlled machine - such as a CNC Torch Table or a CNC Milling Machines - to produce parts automatically by using the CAM files as blueprints.

Example CAM files:

Special Note: The 'Sketchup SKP files to DXF or STL' plugin must first be installed locally. If you do not have the 'Export to DXF or STL' option under Tools, the plugin will need to be downloaded and installed. See below for installation instructions.

Protocol

  1. Open original file in SketchUp.
  2. Ensure that all objects to be exported are aligned flat to the plane of the Z-axis. *Note: 3D objects aligned vertically will NOT be exported successfully.
  3. Select all objects that are needed for the CAM file. *Note: Ensure that all edges of desired objects are selected, faces are NOT exported during conversion, this is normal.
  4. Go to File Menu and select command Tools > Export to DXF or STL.
  5. Select "inches" in dialogue box drop down menu (selected by default), click OK.
  6. In second dialogue box, entities to export, choose best option from drop down that matches needs of destination CAM software. *Note: Most versatile entities are 'polylines', and are typical for DXF files.
  7. For STL export, select 'stl' from the second dialogue box (entities). The option is located at bottom of list in drop-down menu, below 'polylines'.
  8. In the save dialogue, name the file (ensure file extension is correct), choose location, click OK. *Note: Ignore 'Save as type:' drop down menu.
  9. Final dialogue box will report number of faces, lines, and objects converted. Click OK. *Note: Do not be alarmed by the 'objects ignored' count, the script must alter the objects' properties in order to convert the file.
  10. Your CAM file is ready.
  11. Documentation: Open CAM file in appropriate software, capture screen shots and embed images next to your CAM file on wiki.


Plugin Installation

  1. Go to www.guitar-list.com/download-software/convert-sketchup-skp-files-dxf-or-stl in a web browser and download the appropriate version (skp_to_dxf.np for SketchUp 2014).
  2. Navigate to your SketchUp Tools folder, for SketchUp 2014 in Microsoft Windows - C:/Program Files(x86)/SketchUp/SketchUp 2014/Tools
  3. Copy the skp_to_dxf.np file into the Tools folder.
  4. Restart SketchUp, installation is complete.

CAM Files Protocol

Computer Aided Manufacturing (CAM) files are toolpath files that enable a computer-controlled machine - such as a CNC Torch Table or a CNC Milling Machines - to produce parts automatically by using the CAM files as blueprints.

Examples:

  1. CAM files for cutting steel sheet via CNC Torch Table - the Brick Press is an example - where DXF files are used - CEB_Press_CAM_Files
  2. CAM files for 3D printing - tubing for the Tractor Construction Set scale models - where STL files are used - see OSE Rapid Prototyping
  3. Cam files for scale-model laser cutting - DXF files are used - see example at OSE Rapid Prototyping

Protocol

  1. Take the CAD file.
  2. Export into the desired format - such as DXF, STL, or others.
  3. Generate whatever file format is required by the CNC machine, such as Gcode
  4. Start a page on the wiki called - Machine/Module Name - CAM Files. Use Machine Naming Convention.
  5. Open the file, and take a screenshot. Include a screenshot of what the file looks like - embed it next to your CAM file on the wiki - to facilitate identification of the file content.
