TCP Transformation (G48)
• Block N33 defines a circular interpolation up to point (170,90) setting the final tool orientation
to (0º).
The CNC interpolates the XZB axes executing the programmed circular interpolation while
rotating the tool from the current position (-90º) to the programmed final orient position (0º).
Since both orientations are radial, the tool stays radially oriented at all times. In other words,
perpendicular to the path.
• Block N34 positions the tool at (170,120).
• Block N35 cancels the TCP transformation..
Example –C–
Machining of a profile
G18 G90 Selects the ZX plane (G18)
G48 S1 It activates the TCP transformation.
G01 X40 Z0 B0 Positions the tool at (40,0) oriented to (0º)
X100 Movement to (100,0) with tool oriented to (0º)
B-35 Orients the tool to (-35º)
X200 Z70 Movement to (200,70) with tool oriented to (-35º)
B90 Orients the tool to (90º)
G02 X270 Z0 R70 B0 Circular interpolation to (270,0) maintaining the tool
perpendicular to the path.
G01 X340 Movement to (340,0) with tool oriented to (0º)
G48 S0 It cancels the TCP transformation.
