Input coordinate system I-CS
Application
The programmed values in the NC program refer to the input coordinate system I-CS. You use positioning blocks to program the position of the tool.
Description of function
Properties of the input coordinate system I-CS
The input coordinate system I-CS is a three-dimensional Cartesian coordinate system. You use transformations in the working plane coordinate system WPL-CS to define the coordinate origin of the I-CS.
Working plane coordinate system WPL-CS
If no transformations are defined in the WPL-CS, then the position and orientation of the WPL-CS and I-CS are identical.
Positioning blocks in the input coordinate system I-CS
In the input coordinate system I-CS you use positioning blocks to define the position of the tool. The position of the tool defines the position of the tool coordinate system T-CS.
You can define the following positioning blocks:
- Paraxial positioning blocks
- Path functions with Cartesian or polar coordinates
- Straight lines LN with Cartesian coordinates and surface normal vectors (#9 / #4-01-1)
- Cycles

Position display
The following modes of the position display are referenced to the input coordinate system I-CS:
- Nominal pos. (NOML)
- Actual pos. (ACT)
Notes
- The programmed values in the NC program refer to the input coordinate system I-CS. If you do not program any transformations in the NC program, then the origin and position of the workpiece coordinate system W-CS, the working plane coordinate system WPL-CS, and the I-CS are identical.
- During pure 3-axis machining, the workpiece coordinate system W-CS and the working plane coordinate system WPL-CS are identical. In this case, all transformations influence the input coordinate system I-CS.
