Brief description
Programming the transversing paths
The traverse paths of a transverse axis programmed in the part program may be either
radius- or diameter-based. It is possible to switch between the two reference types with the
part program commands DIAMON (DIAMeter ON = diameter) and DIAMOF (DIAMeter OF =
radius). In this way, dimensional information can be taken directly from the technical drawing
without conversion.
Active parts program
When the part program DIAMON (dimensional information as diameter) is active, the
following is true for the transverse axis:
• The setpoint and actual values that refer to the workpiece coordinate system are
• System variables for setpoints and actual values that refer to the workpiece coordinate
• Offsets are entered, programmed and displayed in radius format.
• Programmed end positions are converted to radius values internally.
• The absolute interpolation parameters (e.g. I, J, K) for circular interpolation (G2 and G3)
• Measurement results that were determined by touch trigger probe in the workpiece
• Setpoints and actual values can be read in diameter format in the WCS with the aid of
When the part program command DIAMOF (dimensional information as radius) is active, the
above-mentioned data is always entered, programmed, internally stored, read or displayed
as radius data.
