Cycle 415 PRESET INSIDE CORNER

ISO programming

G415

Application

Touch probe cycle 415 finds the intersection of two lines and defines it as the preset. If desired, the control can also write the point of intersection coordinates to a datum table or the preset table.

Cycle sequence

tch415_1_num
  1. Following the positioning logic, the control positions the touch probe at rapid traverse (value from FMAX column) at touch point 1 (see figure). The control offsets the touch probe in the main axis and the secondary axis by the set-up clearance Q320 + SET_UP + ball-tip radius (in the direction opposite the respective traverse direction)
  2. Positioning logic

  3. Next, the touch probe moves to the entered measuring height and probes the first touch point at the probing feed rate (F column). The probing direction is derived from the number by which you identify the corner.
  1. The touch probe moves to the next touch point 2; the control offsets the touch probe in the secondary axis by the amount of the set-up clearance Q320 + SET_UP + ball-tip radius and then performs the second probing operation
  2. The control positions the touch probe at touch point 3 (same positioning logic as for the first touch point) and performs the probing operation there
  3. The touch probe then moves to touch point 4. The control offsets the touch probe in the main axis by the amount of the set-up clearance Q320 + SET_UP + ball-tip radius and then performs the fourth probing operation
  4. The control returns the touch probe to the clearance height.
  5. Depending on the cycle parameters Q303 and Q305, the control processes the calculated preset, (see Fundamentals of touch probe cycles 4xx for preset setting)
  6. Then the control saves the coordinates of the calculated corner in the Q parameters listed below.
  7. If desired, the control subsequently measures the preset in the touch probe axis in a separate probing operation.
 
Tip

The control always measures the first line in the direction of the minor axis of the working plane.

Notes

 
Notice
Danger of collision!
When running touch probe cycles 400 to 499, all cycles for coordinate transformation must be inactive. There is a danger of collision!
  1. 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.
  2. 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.

Note on programming

  • Before defining this cycle, you must have programmed a tool call to define the touch probe axis.

Distance between the first corner and the second measuring point in the main axis of the working plane. This value has an incremental effect.

Input: 0...99999.9999

Q327 Spacing in 2nd axis?

Distance between the corner and the fourth measuring point in the secondary axis of the working plane. This value has an incremental effect.

Input: 0...99999.9999

Q308 Corner? (1/2/3/4)

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)?

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

Q304 Execute basic rotation (0/1)?

Define whether the control will compensate workpiece misalignment with a basic rotation:

0: No basic rotation

1: Basic rotation

Input: 0, 1

Q305 Number in table?

Indicate the number of the row of the preset table or datum table, in which the control saves the corner 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, the control will write the data to the datum table. The datum is not automatically activated.

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.

 
Tip

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.
