Cycle 413 PRESET OUTS. CIRCLE (#17 / #1-05-1)
ISO programming
G413
Application
Touch probe cycle 413 finds the center of a circular stud and defines this position as the preset. If desired, the control can also write the center point coordinates to a datum table or the preset table.
Instead of Cycle 413 PRESET OUTS. CIRCLE, HEIDENHAIN recommends using the more powerful Cycle 1401 CIRCLE 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 programmed starting angle.
- Then, the touch probe moves along a circular arc, either at measuring height or at clearance height, 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 actual values in the Q parameters listed below.
- If desired, the control subsequently determines the preset in the touch probe axis in a separate probing operation.
Q parameter | Meaning |
---|---|
Q151 | Actual value of center in main axis |
Q152 | Actual value of center in minor axis |
Q153 | Actual value of diameter |
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.
- Before a cycle definition you must have programmed a tool call to define the touch probe axis.
- The control will reset an active basic rotation at the beginning of the cycle.
- This cycle can be executed only in the FUNCTION MODE MILL machining mode.
- The smaller the stepping angle Q247, the less accurately the control can calculate the preset. Minimum input value: 5°
Program the stepping angle to be less than 90°.

Q321 Center in 1st axis? Center of the stud in the main axis of the working plane. This value has an absolute effect. Input: –99999.9999...+9999.9999 | |
Q322 Center in 2nd axis? Center of the stud in the secondary axis of the working plane. If you program Q322 = 0, the control aligns the hole center point to the positive Y axis. If you program Q322 not equal to 0, then the control aligns the hole center point to the nominal position. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q262 Nominal diameter? Approximate diameter of the stud. Enter a value that is more likely to be too large than too small. Input: 0...99999.9999 | |
Q325 Starting angle? Angle between the main axis of the working plane and the first touch point. This value has an absolute effect. Input: –360.000...+360.000 | |
Q247 Intermediate stepping angle? Angle between two measuring points. The algebraic sign of the stepping angle determines the direction of rotation (negative = clockwise) in which the touch probe moves to the next measuring point. If you wish to probe a circular arc instead of a complete circle, then program the stepping angle to be less than 90°. This value has an incremental effect. Input: –120...+120 | |
Q261 Measuring height in probe axis? Coordinate of the ball tip center in the touch probe axis in which the measurement will be performed. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q320 Set-up clearance? Additional distance between touch point and ball tip. Q320 is active in addition to the SET_UP column in the touch probe table. This value has an incremental effect. Input: 0...99999.9999 or PREDEF | |
Q260 Clearance height? Coordinate in the tool axis at which no collision between touch probe and workpiece (fixtures) can occur. This value has an absolute effect. Input: –99999.9999...+99999.9999 or PREDEF | |
Q301 Move to clearance height (0/1)? Define how the touch probe will move between the measuring points: 0: Move to measuring height between measuring points 1: Move to clearance height between measuring points Input: 0, 1 | |
Q305 Number in table? Enter the row number from the preset table / datum table in which the control saves the center coordinates. Depending on Q303, the control writes the entry to the preset table or datum table. If Q303=1, the control will write the data to the preset table. If Q303=0, then the control describes the datum table. The datum is not automatically activated. Input: 0...99999 | |
Q331 New preset in reference axis? Coordinate in the main axis at which the control will set the calculated stud center. Default setting = 0. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q332 New preset in minor axis? Coordinate in the secondary axis at which the control will set the calculated stud center. Default setting = 0. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |

Is entered by the control when old NC programs are loaded see Application 0: Write the calculated preset to the active datum table. The reference system is the active workpiece coordinate system. 1: Write the calculated preset to the preset table. Input: -1, 0, +1 | |

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.
