Cycle 1404 PROBE SLOT/RIDGE (#17 / #1-05-1)
ISO programming
G1404
Application
Touch probe cycle 1404 determines the center of the width of a slot or ridge. The control probes the two opposing touch points. 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 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 1, 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.
- Depending on the selected type of geometry in the parameter Q1115, the control proceeds as follows:
Slot Q1115=0:
- If you program CLEAR. HEIGHT MODE Q1125 with the value 0, 1 or 2, the control positions the touch probe at FMAX_PROBE back to Q260 CLEARANCE HEIGHT.
Ridge Q1115=1:
- Independently of Q1125, the control positions the touch probe at FMAX_PROBE after every touch point back to Q260 CLEARANCE HEIGHT.
- The touch probe moves to the next touch point 2 and performs the second probing procedure at the probing rate F.
- 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 center of the slot or ridge in the main axis, auxiliary axis and tool axis |
Q968 | Measured slot or ridge width |
Q980 to Q982 | Measured deviation of the center of the slot or ridge |
Q998 | Measured deviation of the slot width or ridge width |
Q183 | Workpiece status
|
Q970 | If you have programmed Cycle 1493 EXTRUSION PROBING: Maximum deviation from the center of the slot or ridge |
Q975 | If you have programmed Cycle 1493 EXTRUSION PROBING: Maximum deviation based on the slot width or ridge width |
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.
Notes regarding probing of an extrusion
- When performing an extrusion with Cycle 1493 EXTRUSION PROBING, the extrusion direction is possible only in the main axis or the tool axis.
- In order to measure an extrusion on a rotated slot or ridge in the main axis, you must define the rotational angle using TRANS ROTATION instead of parameter Q1114. The value 0 must be defined for Q1114.
- In order to measure an extrusion on a rotated slot or ridge in the tool axis, you must define the rotational angle using parameter Q1114.
Cycle parameters
Help graphic | 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) | |
Q1113 Width of slot/ridge? Width of the slot or ridge parallel to the secondary axis of the machining plane. This value has an incremental effect. Input: 0...9999.9999 Or – or +:
| |
Q1115 Geometry type (0/1)? Type of object to be probed: 0: Slot 1: Ridge Input: 0, 1 | |
Q1114 Angle of rotation? Angle about which the slot or the ridge 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 with a slot: –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. The parameter takes effect only with Q1115=+1 (slot). 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.
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.
