Cycle 414 PRESET OUTS. CORNER (#17 / #1-05-1)
ISO programming
G414
Application
Touch probe cycle 414 finds the intersection of two lines and defines it as the preset. If desired, the control can also write the point of intersection coordinates to a datum table or the preset table.
Instead of Cycle 414 PRESET OUTS. CORNER, HEIDENHAIN recommends using the more powerful Cycle 1416 INTERSECTION PROBING.

Cycle run
- The control positions the touch probe to the pre-position of the first touch point 1, using positioning logic.
- Next, the touch probe moves to the entered measuring height and probes the first touch point at the probing feed rate (F column). The control derives the probing direction automatically from the 3rd measuring point.
- The touch probe then moves to the next touch point 2 and probes again.
- The control positions the touch probe to touch point 3 and then to touch point 4 to probe two more times.
- The control returns the touch probe to the clearance height.
- Depending on the cycle parameters Q303 and Q305, the control processes the determined preset, (see Fundamentals of touch probe cycles 408 to 419 for preset setting).
- Then the control saves the coordinates of the calculated corner in the Q parameters listed below.
- If desired, the control subsequently determines the preset in the touch probe axis in a separate probing operation.
The control always measures the first line in the direction of the minor axis of the working plane.
Q parameter | Meaning |
---|---|
Q151 | Actual value of corner in reference axis |
Q152 | Actual value of corner in minor axis |
Definition of the corner
By defining the positions of the measuring points 1 and 3, you also determine the corner at which the control sets the preset (see the following figure and table below).
Corner | X coordinate | Y coordinate |
---|---|---|
A | Point 1 greater than point 3 | Point 1 less than point 3 |
B | Point 1 less than point 3 | Point 1 less than point 3 |
C | Point 1 less than point 3 | Point 1 greater than point 3 |
D | Point 1 greater than point 3 | Point 1 greater than point 3 |
Notes
- Do not activate the following cycles before the use of touch probe cycles:
- Cycle 7 DATUM SHIFT
- Cycle 8 MIRRORING
- Cycle 10 ROTATION
- Cycle 11 SCALING FACTOR
- Cycle 26 AXIS-SPECIFIC SCALING
- Reset any coordinate transformations beforehand.
- This cycle can be executed only in the FUNCTION MODE MILL machining mode.
- The control will reset an active basic rotation at the beginning of the cycle.
Note on programming
- Before defining this cycle, you must have programmed a tool call to define the touch probe axis.

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.
