Cycle 416 PRESET CIRCLE CENTER (#17 / #1-05-1)
ISO programming
G416
Application
Cycle run
- The control positions the touch probe at the entered center of the first hole 1, using positioning logic.
- Then the probe moves to the entered measuring height and probes four points to determine the first hole center point.
- The touch probe returns to the clearance height and then to the position entered as center of the second hole 2.
- The control moves the touch probe to the entered measuring height and probes four points to determine the second hole center point.
- The touch probe returns to the clearance height and then to the position entered as center of the third hole 3.
- The control moves the touch probe to the entered measuring height and probes four points to determine the third hole center point.
- 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 reference axis |
Q152 | Actual value of center in minor axis |
Q153 | Actual value of bolt hole circle 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.
- 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.

Q273 Center in 1st axis (nom. value)? Bolt hole circle center (nominal value) in the main axis of the working plane. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q274 Center in 2nd axis (nom. value)? Bolt hole circle center (nominal value) in the secondary axis of the working plane. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q262 Nominal diameter? Enter the approximate bolt hole circle diameter. The smaller the hole diameter, the more exact the nominal diameter must be. Input: 0...99999.9999 | |
Q291 Polar coord. angle of 1st hole? Polar coordinate angle of the first hole center in the working plane. This value has an absolute effect. Input: –360.000...+360.000 | |
Q292 Polar coord. angle of 2nd hole? Polar coordinate angle of the second hole center in the working plane. This value has an absolute effect. Input: –360.000...+360.000 | |
Q293 Polar coord. angle of 3rd hole? Polar coordinate angle of the third hole center in the working plane. This value has an absolute effect. Input: –360.000...+360.000 | |
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 | |
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 | |
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 bolt-hole 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 bolt-hole circle center. Default setting = 0. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q303 Meas. value transfer (0,1)? Define whether the calculated preset will be saved in the datum table or in the preset table: -1: Do not use. 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 | |
Q381 Probe in TS axis? (0/1) Define whether the control will also set the preset in the touch probe axis: 0: Do not set the preset in the touch probe axis 1: Set the preset in the touch probe axis Input: 0, 1 | |
Q382 Probe TS axis: Coord. 1st axis? Coordinate of the touch point in the main axis of the working plane; the preset will be set at this point in the touch probe axis. Only effective if Q381 = 1. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q383 Probe TS axis: Coord. 2nd axis? Coordinate of the touch point in the secondary axis of the working plane; the preset will be set at this point in the touch probe axis. Only effective if Q381 = 1. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q384 Probe TS axis: Coord. 3rd axis? Coordinate of the touch point in the touch probe axis; the preset will be set at this point in the touch probe axis. Only effective if Q381 = 1. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q333 New preset in TS axis? Coordinate in the touch probe axis at which the control will set the preset. Default setting = 0. 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 added to SET_UP (touch probe table), and is only active when the preset is probed in the touch probe axis. This value has an incremental effect. Input: 0...99999.9999 or PREDEF |
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.
