Robot Working Frames
TOOL
Tool is a Robot property which informs the system to use the specified location as the tool transformation. It defines the position and orientation of the tool tip in relation to the center of the tool flange. The default tool transformation is the NULL transformation, which can be expressed as TOOL = #{0,0,0,0,0,0} Example: Puma.tool = #{25,0,100,0,45,0}
Another example of tool coordinate calculation:
BASE
Base is a Robot property which informs the system to use the specified location as the base transformation. It defines the position and orientation of the arm in the cell according to the WORLD reference. The default base transformation is the NULL transformation, which can be expressed as Puma.base = #{0,0,0,0,0,0}
MachineTable
MachineTable is a Robot property which informs the system to use the specified location as the machinetable transformation. It defines the position and orientation machine working frame relative to the BASE reference. The default machinetable transformation is the NULL transformation, which can be expressed as Puma.MachineTable = #{0,0,0,0,0,0}

| The inverse usage of MachineTable and WorkPiece properties |
WorkPiece
WorkPiece is a Robot property which informs the system to use the specified location as the workpiece transformation. It defines the position and orientation of work-piece relative to the MACHINE TABLE reference. The default base transformation is the NULL transformation, which can be expressed as Puma.WorkPiece = #{0,0,0,0,0,0}
So we have:
Pbase=Base:Pworld:Tool
Pbase=MachineTable:WorkPiece:PWorkP
For the given setup user frames will be:
Base = #{300,200,1000,0,180,180}
Tool = #{50,0,0,90,45,0}
MachineTable = #{400,100,0,0,0,0}
WorkPiece = #{20,70,150,0,90,-90}
Therefore we have:
PWP= WorkPiece-1: MachineTable-1:Base:PWorld:Tool
