Touch probe table tchprobe.tp (#17 / #1-05-1)

Application

In the touch probe table tchprobe.tp you define the parameters of the touch probe for the touching process, such as the probing feed rate. If you use several touch probes, you can save separate parameters for each touch probe.

Description of function

The file name of the touch probe table is tchprobe.tp and this table must be stored in the folder TNC:\table.

Parameters of the touch probe table tchprobe.tp

The touch probe table tchprobe.tp provides the following parameters:

Parameter

Meaning

NO

Sequential number of touch probe

You enter this number in the TP_NO parameter in the tool management. The control then associates the data from the touch-probe table with the tool management.

Input: 1...99

TYPE

Selection of the touch probe?

 
Tip

The following values are available for the TS 642 touch probe:

  • TS642-3: The touch probe is activated by a conical switch. This mode is not supported.
  • TS642-6: The touch probe is activated by an infrared signal. Select this mode.

Input: TS120, TS220, TS249, TS260, TS440, TS444, TS460, TS630, TS632, TS640, TS642-3, TS642-6, TS649, TS740, TS 760, KT130, OEM

STYLUS

Shape of the stylus

  • SIMPLE: Straight stylus
  • L-TYPE: L-shaped stylus

If you do not define the parameter, the control uses SIMPLE

CAL_OF1

TS center misalignmt. ref. axis? [mm]

Depending on the selection of STYLUS parameter, this parameter has the following function:

  • SIMPLE: Offset of the touch probe axis to the spindle axis in the main axis
  • L-TYPE: Length of extension on an L-shaped stylus

Required when ON is selected in parameter TRACK

The control describes this value in connection with the calibration cycle.

Input: –99999.9999...+99999.9999

CAL_OF2

TS center misalignmt. aux. axis? [mm]

Offset of the touch probe axis to the spindle axis in the secondary axis

Required when ON is selected in parameter TRACK

The control describes this value in connection with the calibration cycle.

Input: –99999.9999...+99999.9999

CAL_ANG

Spindle angle for calibration?

Depending on the selection of STYLUS parameter, this parameter has the following function:

  • SIMPLE: Prior to calibrating or probing, the control orients the touch probe with this spindle angle (if possible).
  • L-TYPE: The control orients the extension using the spindle angle.

Prior to calibrating or probing, the control aligns the touch probe with the spindle orientation angle (if possible).

Required when ON is selected in parameter TRACK

Input: 0.0000...359.9999

F

Probing feed rate? [mm/min]

In the machine parameter maxTouchFeed (no. 122602), the machine manufacturer defines the maximum probing feed rate.

If F is greater than the maximum probing feed rate, then the maximum probing feed rate will be used.

Input: 0...9999

FMAX

Rapid traverse in probing cycle? [mm/min]

Feed rate at which the control pre-positions the touch probe and positions it between the measuring points

Input: +10...+99999

DIST

Maximum measuring range? [mm]

If the stylus is not deflected in a probing process within the defined value, the control will display an error message.

Input: 0.00100...99999.99999

SET_UP

Set-up clearance? [mm]

Distance of touch probe from the defined touch point when pre-positioning

The smaller this value is, the more exactly you must define the touch point position. Safety clearances defined in the touch probe cycle are added to this value.

Input: 0.00100...99999.99999

F_PREPOS

Pre-position at rapid? ENT/NOENT

Speed for pre-positioning:

  • FMAX_PROBE: Pre-position at the speed from FMAX
  • FMAX_MACHINE: Pre-position at machine rapid traverse

Input: FMAX_PROBE, FMAX_MACHINE

TRACK

Probe oriented? Yes=ENT/No=NOENT

Orienting the infrared touch probe in each probing process:

  • ON: The control orients the touch probe in the defined probing direction. In this way, the stylus is always deflected in the same direction, improving measuring accuracy.
  • OFF: The control will not orient the touch probe.

When selecting L-TYPE in the STYLUS parameter, ON must be selected.

If you change the TRACK parameter, you must recalibrate the touch probe.

Input: ON, OFF

SERIAL

Serial number?

The control automatically edits this parameter of touch probes with an EnDat interface.

Input: Text width 15

REACTION

Reaction? EMERGSTOP=ENT/NCSTOP=NOENT

As soon as touch probes with a collision protection adapter detect a collision, they react by resetting the ready signal.

Reaction to resetting the ready signal:

  • NCSTOP: Interrupt NC program
  • EMERGSTOP: Emergency stop, quick braking of the axes

Input: NCSTOP, EMERGSTOP

Editing the touch probe table

To edit the touch probe table:

    1. Select the Tables operating mode

    1. Select Add
    2. The control opens the Quick selection and the Open File workspaces.
    3. Select the tchprobe.tp file in the Open File workspace

    1. Select Open
    2. The control opens the Touch probes application.

    1. Activate Edit
    2. Select the desired value
    3. Edit the value

    Notes

    • You can also edit the touch probe table values in the tool management.
    • If you want to archive tool tables or use them for simulation, save them with different file names and the corresponding file extension.
    • In the machine parameter overrideForMeasure (no. 122604), the machine manufacturer defines whether you will be allowed to change the feed rate with the feed-rate potentiometer during probing.
