COORDINATE TRANSFORMATION
The description of the general coordinate transformation is divided into three basic functions:
• Movement in an inclined plane (G49).
• Tool movement according to the tool coordinate system (G47).
• TCP transformation, Tool Center Point (G48).
For a better understanding of coordinate transformation, three machine coordinate systems will be
considered in the following examples.
• Machine coordinate system. X Y Z in the figures.
• Part coordinate system. X' Y' Z' in the figures.
• Tool coordinate system. X" Y" Z" in the figures.
When no transformation has been made and the spindle is in the starting position, the three
coordinate systems coincide. Figure on the left.
When turning the spindle, the tool coordinate system (X" Y" Z") changes. Figure on the right.
If, also, an inclined plane is selected (G49), the part coordinate system also changes (X', Y', Z').
