Cycle 1401 CIRCLE PROBING (#17 / #1-05-1)
ISO programming
G1401
Application
Touch probe cycle 1401 determines the center point of a circular pocket or circular stud. You can transfer the deviations as correction values to the active row of the preset table.
Cycle 1493 EXTRUSION PROBING allows you to repeat the touch points in a chosen direction and for a defined distance along a straight line.
Cycle run
- The control positions the touch probe to the pre-position of the first touch point, using positioning logic.
- The control then positions the touch probe to the entered measuring height Q1102 and performs the first probing procedure with the probing feed rate F from the touch probe table.
- If you program CLEAR. HEIGHT MODE Q1125, then the control positions the touch probe at FMAX_PROBE back to the clearance height Q260.
- The control positions the touch probe to the next touch point.
- The control moves the touch probe to the entered measuring height Q1102 and measures the next touch point.
- Depending on the definition of Q423 NO. OF PROBE POINTS, steps 3 to 5 repeat themselves.
- The control returns the touch probe to the clearance height Q260.
- The control saves the measured positions in the following Q parameters. If Q1120 TRANSFER POSITION is defined with the value 1, then the control corrects the ascertained deviations in the active row of the preset table.
Q parameter | Meaning |
---|---|
Q950 to Q952 | Measured circle center point in the main axis, secondary axis, and tool axis |
Q966 | Measured diameter |
Q980 to Q982 | Measured deviation of the circle center |
Q996 | Measured deviation of the diameter |
Q183 | Workpiece status
|
Q970 | If you have programmed Cycle 1493 EXTRUSION PROBING: Maximum deviation starting from the first circle center |
Q973 | If you have programmed Cycle 1493 EXTRUSION PROBING: Maximum deviation starting from Diameter 1 |
Notes
- 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.

Q1100 1st noml. position of ref. axis? Absolute nominal position of the center in the main axis of the working plane. Input: –99999.9999...+99999.9999 or enter ?, +, – or @:
| |
Q1101 1st noml. position of minor axis? Absolute nominal position of the center in the secondary axis of the working plane Input: –99999.9999...+9999.9999 or optional input (see Q1100) | |
Q1102 1st nominal position tool axis? Absolute nominal position of the first touch point in the tool axis Input: –99999.9999...+9999.9999 or optional input (see Q1100) | |
Q1116 Diameter of 1st position? Diameter of the first hole or the first stud Input: 0...9999.9999 or optional input:
| |
Q1115 Geometry type (0/1)? Type of object to be probed: 0: Hole 1: Stud Input: 0, 1 | |
Q423 Number of probes? Number of touch points on the diameter Input: 3, 4, 5, 6, 7, 8 | |
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 | |
Q1119 Arc angular length? Angular range in which the touch points are distributed. Input: –359.999...+360.000 | |
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 | |
Q1125 Traverse to clearance height? Positioning behavior between the touch points –1: Do not move to the clearance height. 0, 1: Move to the clearance height before and after the cycle. Pre-positioning occurs at FMAX_PROBE. 2: Move to the clearance height before and after each touch point. Pre-positioning occurs at FMAX_PROBE. Input: –1, 0, +1, +2 | |
Q309 Reaction to tolerance error? Reaction when tolerance is exceeded: 0: Do not interrupt program run when tolerance is exceeded. The control does not open a window with the results. 1: Interrupt program run when tolerance is exceeded. The control opens a window with the results. 2: The control does not open a window if rework is necessary. The control opens a window with results and interrupts the program if the actual position is at scrap level. Input: 0, 1, 2 | |
Q1120 Transfer position? Define which touch point will be used to correct the active preset: 0: No correction 1: Correction based on the 1st touch point. The control corrects the active preset by the amount of deviation between the nominal and actual position of the 1st touch point. Input: 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.
