Cycle 1403 RECTANGLE PROBING (#17 / #1-05-1)

ISO programming

G1403

Application

Touch probe cycle 1403 determines the center and both lengths of a rectangle.

The control probes opposing touch points, one on each side. The control probes perpendicularly to the side surface of the object to be probed, even if the object to be probed is rotated.

You can transfer the deviations from the nominal position 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 1493 EXTRUSION PROBING (#17 / #1-05-1)

Cycle run

  1. The control positions the touch probe to the pre-position of the first touch point 1, using positioning logic.
  2. Positioning logic

  3. 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.
  4. Depending on the selected type of geometry in the parameter Q1115, the control proceeds as follows:
    • For a pocket (Q1115=0) and depending on the definition of Q1125 CLEAR. HEIGHT MODE, the control retracts the touch probe at FMAX_PROBE to the clearance height Q260 .
    • For an island (Q1115=1) the control retracts the touch probe at FMAX_PROBE back to the clearance height Q260 after each probe point, regardless of Q1125.
  5. The touch probe moves to the next touch point 2 and performs the second probing procedure at the probing rate F.
  6. The control repeats Steps 1 to 4 until all four touch points have been probed.
  7. The control saves the measured results 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.

Notes

 
Notice
Danger of collision!
When running touch probe cycles 444 or 14xx, no NC functions for coordinate transformation must be active. Risk of collision!
  1. 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
  2. Reset any coordinate transformations before the cycle call.
  • This cycle can be executed only in the FUNCTION MODE MILL machining mode.
  • When performing an extrusion with Cycle 1493 EXTRUSION PROBING, the only possible extrusion direction is the tool axis.
  • Observe the fundamentals of touch probe cycles 14xx.

Parameter

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 touch points in the tool axis

Input: –99999.9999...+9999.9999 or optional input (see Q1100)

Q1111 First side length?

Length of rectangle, parallel to the main axis of the working plane

Input: 0...9999.9999 Or or +:

Q1112 Second side length?

Width of rectangle, parallel to the secondary axis of the working plane.

Input: 0...9999.9999 Or or +:

Q1115 Geometry type (0/1)?

Type of object to be probed:

0: Pocket

1: Island

Input: 0, 1

Q1114 Angle of rotation?

Angle by which the rectangle is rotated. The center of rotation is in Q1100 and Q1101. This value has an absolute effect.

Input: 0...359999

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.

This parameter is in effect only for Q1115=+1 (pocket).

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 of the active preset based on the center point. The control corrects the active preset by the amount of the deviation of the nominal and actual position of the center.

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.

 
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.
