Touch probe cycle 403 determines a workpiece misalignment by measuring two points, which must lie on a straight line. The control compensates the determined misalignment by rotating the A, B, or C axis. The workpiece can be clamped in any position on the rotary table.
Application
Cycle sequence

- Following the positioning logic, the control positions the touch probe at rapid traverse (value from the FMAX column) to the programmed touch point 1. The control offsets the touch probe by the set-up clearance in the direction opposite the defined traverse direction
- Next, the touch probe moves to the entered measuring height and probes the first touch point at the probing feed rate (F column).
- The touch probe then moves to the next touch point 2 and probes again.
- The control returns the touch probe to the clearance height and rotates the rotary axis, which was defined in the cycle, by the measured value. Optionally, you can specify whether the control is to set the determined rotation angle to 0 in the preset table or in the datum table.
Notes
- Check for possible collisions between the tool and any elements positioned on the table
- Select the clearance height to prevent collisions
- After alignment, check the position of the rotary axis.
- The following cycles must not be activated before a touch probe cycle: Cycle 7 DATUM SHIFT, Cycle 8 MIRRORING, Cycle 10 ROTATION, Cycle 11 SCALING FACTOR, and Cycle 26 AXIS-SPECIFIC SCALING.
- Reset any coordinate transformations beforehand.
- This cycle can only be executed in the FUNCTION MODE MILL machining mode.
- The control will reset an active basic rotation at the beginning of the cycle.

Q272 Meas. axis (1/2/3, 1=ref. axis)? Axis in which the measurement will be made: 1: Main axis = measuring axis 2: Secondary axis = measuring axis 3: Touch probe axis = measuring axis Input: 1, 2, 3 | |
Q267 Trav. direction 1 (+1=+ / -1=-)? Direction in which the touch probe will approach the workpiece: –1: Negative traverse direction +1: Positive traverse direction Input: –1, +1 | |
Q261 Measuring height in probe axis? Coordinate of the ball tip center in the touch probe axis in which the measurement will be performed. The value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q320 Set-up clearance? Additional distance between touch point and ball tip. Q320 is 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. The value has an absolute effect. Input: –99999.9999...+99999.9999 or PREDEF | |
Q301 Move to clearance height (0/1)? Specify how the touch probe moves between measuring points: 0: Move at measuring height between measuring points 1: Move at clearance height between measuring points Input: 0, 1 | |
Q312 Axis for compensating movement? Define the rotary axis in which the control will compensate the measured misalignment: 0: Automatic mode – the control uses the active kinematics to determine the rotary axis to be aligned. In Automatic mode the first rotary axis of the table (as viewed from the workpiece) is used as compensation axis. This is the recommended setting! 4: Compensate misalignment with rotary axis A 5: Compensate misalignment with rotary axis B 6: Compensate misalignment with rotary axis C Input: 0, 4, 5, 6 | |
Q337 Set to zero after alignment? Define whether the control will set the angle of the aligned rotary axis to 0 in the preset table or in the datum table after the alignment. 0: Do not set the angle of the rotary axis to 0 in the table after the alignment 1: Set the angle of the rotary axis to 0 in the table after the alignment Input: 0, 1 | |
Q305 Number in table? Specify the number of the row in the preset table in which the control will enter the basic rotation. Q305 = 0: The rotary axis is zeroed in row number 0 of the preset table. The control will make an entry in the OFFSET column. In addition, all other values (X, Y, Z, etc.) of the currently active preset will be transferred to row 0 of the preset table. In addition, the control activates the preset from row 0. Q305 > 0: Specify the number of the row in the preset table in which the control will zero the rotary axis. The control will make an entry in the OFFSET column of the preset table. Q305 depends on the following parameters:
Input: 0...99999 | |
Q303 Meas. value transfer (0,1)? Define whether the calculated preset will be saved in the datum table or in the preset table: 0: Write the calculated preset to the active datum table as a datum shift. The reference system is the active workpiece coordinate system. 1: Write the calculated preset to the preset table. Input: 0, 1 | |
Q380 Ref. angle in ref. axis? Angle to which the control will align the probed straight line. Only effective if the rotary axis is in automatic mode or if C is selected (Q312 = 0 or 6). Input: 0...360 |
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.
