WARNING
indicates that death or severe personal injury may result if proper precautions are not taken.
CAUTION
indicates that minor personal injury can result if proper precautions are not taken.
NO TICE
indicates that property damage can result if proper precautions are not taken.
If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of
injury to persons with a safety alert symbol may also include a warning relating to property damage.

  • Page 16: Coordinate Systems

    Coordinate systems As a rule, a coordinate system is formed from three mutually perpendicular coordinate axes. The positive directions of the coordinate axes are defined using the Cartesian coordinate system. The coordinate system is related to the workpiece and programming takes place independently of whether the tool or the workpiece is being traversed. When programming, it is always assumed that the tool traverses relative to the coordinate system of the workpiece, which is intended to be stationary.
  • Page 17 Wo rkpiece coordinate system (WCS) To describe the geometry of a workpiece in the workpiece program, a right-handed, right-angled coordinate system is also used. Generally, X0/Y0 of the WCS is set at the center, edge or corner of the workpiece while Z0 is set on the top surface of the workpiece.
