Cycle 1410 PROBING ON EDGE (#17 / #1-05-1)
ISO programming
G1410
Application
Touch probe cycle 1410 allows you to determine workpiece misalignment by probing two points on an edge. The cycle determines the rotation based on the difference between the measured angle and the nominal angle.
Cycle 1493 EXTRUSION PROBING allows you to repeat the touch points in a chosen direction and for a defined distance along a straight line.

The cycle also offers the following possibilities:
- If the coordinates of the touch points are not known, then you can execute the cycle in semi-automatic mode.
- Optionally, the cycle can monitor the tolerances. That way you can monitor the position and size of an object.
- If you have already determined the exact position beforehand, then you can define the value in the cycle as the nominal position.
Cycle run
- The control positions the touch probe to the pre-position of the first touch point 1, using positioning logic.
- The touch probe then moves to the entered measuring height Q1102 and performs the first probing procedure at probing speed F from the touch probe table.
- The control offsets the touch probe by the amount of the set-up clearance in the direction opposite to the direction of probing.
- If you program CLEAR. HEIGHT MODE Q1125, then the control positions the touch probe at FMAX_PROBE back to the clearance height Q260.
- The touch probe then moves to the next touch point 2 and probes again.
- The control then positions the touch probe back to the clearance height (depending on Q1125) and stores the determined values in the following Q parameters:
Q parameter | Meaning |
---|---|
Q950 to Q952 | Measured position 1 in the main axis, secondary axis, and tool axis |
Q953 to Q955 | Measured position 2 in the main axis, secondary axis, and tool axis |
Q964 | Measured basic rotation |
Q965 | Measured table rotation |
Q980 to Q982 | Measured deviation from the first touch point |
Q983 to Q985 | Measured deviation from the second touch point |
Q994 | Measured angle deviation of basic rotation |
Q995 | Measured angle deviation of table rotation |
Q183 | Workpiece status
|
Q970 | If you have programmed Cycle 1493 EXTRUSION PROBING: Maximum deviation starting from the first touch point |
Q971 | If you have programmed Cycle 1493 EXTRUSION PROBING: Maximum deviation starting from the second touch point |
Notes
- Move to the clearance height between every object or touch point. Program Q1125 CLEAR. HEIGHT MODE so as not to be equal to -1.
- Do not activate the following NC functions before using the touch-probe cycle:
- Cycle 8 MIRRORING
- Cycle 11 SCALING FACTOR
- Cycle 26 AXIS-SPECIFIC SCALING
- TRANS MIRROR
- Reset any coordinate transformations before the cycle call.
- This cycle can be executed only in the FUNCTION MODE MILL machining mode.
- Observe the fundamentals of touch probe cycles 14xx.
Note about rotary axes:
- If you determine the basic rotation in a tilted machining plane, then note the following:
- If the current coordinates of the rotary axes and the defined tilting angle (3D-ROT menu) match, then the working plane is consistent. The control calculates the basic rotation in the input coordinate system I-CS.
- If the current coordinates of the rotary axes and the defined tilting angle (3D-ROT menu) do not match, then the machining plane is inconsistent. The control calculates the basic rotation in the workpiece coordinate system W-CS based on the tool axis.
- The optional machine parameter chkTiltingAxes (no. 204601) allows the machine manufacturer to define whether the control checks for a matching tilting situation. If no check is defined, then the control assumes a consistent machining plane. The basic rotation is then calculated in the I-CS.
Aligning the rotary table axes:
- The control can align the rotary table only if the measured rotation can be compensated for using a rotary table axis. This axis must be the first rotary table axis (as viewed from the workpiece).
- To align the rotary table axes (Q1126 not equal to 0), you must apply the rotation (Q1121 not equal to 0). Otherwise, the control will display an error message.
- The alignment with rotary table axes is possible only if no basic rotation was set before.

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.
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.
