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.

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

NC programs contained in this User's Manual are suggestions for solutions. The NC programs or individual NC blocks must be adapted before being used on a machine.

Change the following contents as needed:

  • Tools
  • Cutting parameters
  • Feed rates
  • Clearance height or safe position
  • Machine-specific positions (e.g., with M91)
  • Paths of program calls

Some NC programs depend on the machine kinematics. Adapt these NC programs to your machine kinematics before the first test run.

In addition, test the NC programs using the simulation before the actual program run.

 
Tip

With a program test you determine whether the NC program can be used with the available software options, the active machine kinematics and the current machine configuration.

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.
