Cycle 0 REF. PLANE (#17 / #1-05-1)

ISO programming

G55

Application

The touch probe cycle measures any position on the workpiece in a selectable axis direction.

 
Tip

Instead of Cycle 0 REF. PLANE, HEIDENHAIN recommends using the more powerful Cycle 1400 POSITION PROBING.

Cycle run

  1. In a 3D movement, the touch probe moves at rapid traverse (value from the FMAX column) to the pre-position 1 programmed in the cycle.
  2. Next, the touch probe performs probing at the probing feed rate (F column). The probing direction must be defined in the cycle.
  3. After the control has saved the position, the probe retracts to the starting point and saves the measured coordinate in a Q parameter. In addition, the control stores the coordinates of the position of the touch probe at the time of the triggering signal in parameters Q115 to Q119. For the values in these parameters the control does not account for the stylus length and radius.

Notes

 
Notice
Danger of collision!
The control moves the touch probe in a 3D movement at rapid traverse to the pre-position programmed in the cycle. Depending on the previous position of the tool, there is danger of collision!
  1. Pre-position to a position where there is no danger of collision when the programmed pre-positioning point is approached
  • This cycle can be executed only in the FUNCTION MODE MILL machining mode.

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.
