In FreeCAD, a 3d mesh drawing can be exported as an stl file; alternatively, a 2d drawing can be exported as a dxf or svg file. Any of these files can then be imported in PyCAM, in which toolpaths can be generated for those drawings. These toolpaths can then be exported from PyCAM as a gcode file. EMC2 can then import the gcode file and simulate the toolpath, plus send logic signals to an external electronic controller that moves a machine to correspond to the toolpath. This toolchain allows digital fabrication to be utilized for the construction of the industrial robot.
 
=Force Analysis=
 
*Format
 
Force is expressed in newtons (N)
 
Maximum absolute displacement is expressed in millimeters (mm)
 
Dimensions are expressed in inches (“)
 
 
*A36 Steel Specifications
 
Poisson Ratio = 0.285
 
Young's Modulus = 200GPa
 
 
*Some results strange - retesting to be done, remainder of force analysis to be posted, new analysis for different robot components to be completed
