Touch probe cycle 402 measures the center points of two cylindrical studs. The control then calculates the angle between the main axis of the working plane and the line connecting the stud center points. With the basic rotation function, the control compensates the calculated value. As an alternative, you can also compensate the determined misalignment by rotating the rotary table.

Q268 1st stud: center in 1st axis? Center of the first stud in the main axis of the working plane. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q269 1st stud: center in 2nd axis? Center of the first stud in the secondary axis of the working plane. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q313 Diameter of stud 1? Approximate diameter of the first stud. Enter a value that is more likely to be too large than too small. Input: 0...99999.9999 | |
Q261 Meas. height stud 1 in TS axis? Coordinate of the ball tip center (= touch point) in the touch probe axis at which stud 1 will be measured. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q270 2nd stud: center in 1st axis? Center of the second stud in the main axis of the working plane. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q271 2nd stud: center in 2nd axis? Center of the second stud in the secondary axis of the working plane. This value has an absolute effect. Input: –99999.9999...+99999.9999 | |
Q314 Diameter of stud 2? Approximate diameter of the second stud. Enter a value that is more likely to be too large than too small. Input: 0...99999.9999 | |
Q315 Meas. height stud 2 in TS axis? Coordinate of the ball tip center (= touch point) in the touch probe axis at which stud 2 will be measured. 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)? 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 | |
Q307 Preset value for rotation angle If the misalignment is measured relative to any straight line other than the main axis, enter the angle of this reference line. For the basic rotation, the control will then calculate the difference between the value measured and the angle of the reference line. This value has an absolute effect. Input: –360.000...+360.000 | |
Q305 Number in table? Enter the number of a row in the preset table. The control will make the corresponding entry in the following row: Q305 = 0: The rotary axis will be zeroed in row 0 of the preset table. The control will make an entry in the OFFSET column. (Example: For tool axis Z, the entry is made in C_OFFS). 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: The rotary axis will be zeroed in the preset table row specified here. The control will make an entry in the corresponding OFFSET column of the preset table. (Example: For tool axis Z, the entry is made in C_OFFS). Q305 depends on the following parameters:
Input: 0...99999 | |
Q402 Basic rotation/alignment (0/1) Define whether the control will set the determined misalignment as a basic rotation or will compensate it by rotating the rotary table: 0: Set basic rotation: The control saves the basic rotation (example: for tool axis Z, the control uses column SPC) 1: Rotate the rotary table: An entry will be made in the corresponding Offset column of the preset table (example: for tool axis Z, the control uses the C_OFFS column); in addition, the corresponding axis will be rotated Input: 0, 1 | |
Q337 Set to zero after alignment? Define whether the control will set the position display of the corresponding rotary axis to 0 after the alignment: 0: The position display is not set to 0 after the alignment 1: After the alignment, the position display is set to 0, provided you have defined Q402 = 1 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.
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.
