TCP Transformation (G48)
Example –A–
Circular interpolation keeping tool orientation fixed.
• Block N20 selects the ZX plane (G18) and positions the tool at the starting point (30,90).
• Block N21 turns TCP transformation on.
• Block N22 positions the tool at (100,20) orienting it to -60º.
The CNC interpolates the XZB axes executing the programmed linear interpolation while rotating
the tool from the starting position (0º) to the programmed final orient position (-60º).
• Block N23 makes a circular interpolation to point (170,90) maintaining the same tool orientation
along the whole path.
• Block N24 positions the tool at (170,120) orienting it to 0º.
The CNC interpolates the XZB axes executing the programmed linear interpolation while rotating
the tool from the current position (-60º) to the programmed final orient position (0º).
• Block N25 turns TCP transformation off.
Example –B–
Circular interpolation with the tool perpendicular to the path.
• Block N30 selects the ZX plane (G18) and positions the tool at the starting point (30,90).
• Block N31 turns TCP transformation on.
• Block N32 positions the tool at (100,20) orienting it to -90º.
The CNC interpolates the XZB axes executing the programmed linear interpolation while rotating
the tool from the starting position (0º) to the programmed final orient position (-90º).
