Coordinate transformation between coordinate systems (#TRANSFORM)
 | This function is an additional option requiring a license. |
The #TRANSFORM command is used to convert any coordinates of a 3D point from one stack level to another stack level in the NC program based on the current CS stack. The transformation calculation required for this consists of a combination of kinematic and Cartesian forward or backward transformation, depending on the structure of the CS stack.
Auxiliary and additional axes are only taken into account in the transformation calculation with regard to their zero point displacements between the stack planes.
The #TRANSFORM command is also used for transformations that are already active (#CS SELECT) in the channel.
Syntax of Transformation command: |
#TRANSFORM [<CS_source>] [<CS_dest> ] [POS_X>, <POS_Y>, <POS_Z> ] [ [ {<POS_aux>=..} ] ] |
<CS_source> | Name of the tracked CS with maximum of 8 characters. |
<CS_dest> | Name of the destination CS with maximum of 8 characters. |
<POS_X, Y, Z> | 3 components of the point to be transformed in [mm, inch] in the input CS. |
<POS_aux>=.. | Input coordinates of the auxiliary and additional axes |
| An error message is generated it:
|
The result of the transformation calculation is supplied in special axis-specific variables (V.A.). The axis can be programmed either by name or by axis index:
Syntax of Result variables |
V.A.TRANSFORM.<axis_name> Axis-specific coordinate after calculation in [mm, inch] or V.A.TRANSFORM[<axis_index>] Axis-specific coordinate after calculation in [mm, inch]

Programming Example
Example 1, basic configuration is a 5-axis kinematic with CS stack.
Transformation for the point (50,0,10) with tracking axis positions A10 and B20 from the ACS system to the WCS system. A kinematic Cartesian forward transformation is executed.
#TRANSFORM [ACS] [WCS] [50, 0, 10] [A10 B20]
Example 2, basic configuration is a 5-axis kinematic with CS stack.
Transformation for the point (10,-10,15) with tracking axis positions A45 and B90 from the MCS system to the ACS system. A simple kinematic backward transformation is executed.
#TRANSFORM [MCS] [ACS] [10, -10, 15] [A45 B90]
