Measuring the tool by scratching

Application

Not all machines are equipped with a tool touch probe for measuring a tool. The Tool measured touch probe function enables determining the tool dimensions by scratching a workpiece.

Requirement

  • Touch Probe Functions software option (#17 / #1-05-1)
  •  
    Tip

    If you are using a HEIDENHAIN touch probe with EnDat interface, then the Touch Probe Functions software option (#17 / #1-05-1) is automatically enabled. Werkstück-Tastsystem kalibrieren_01 Werkstück-Tastsystem kalibrieren_01

Description of function

You do not use a 3D touch probe for scratching, but the tool to be measured. In the scratching process, approach the tool carefully to a workpiece surface until you can see a thin chip being removed. The handwheel allows obtaining a higher accuracy.

In the X or Y probing directions, the tool radius can be determined. When selecting probing direction Z, the tool length is measured.

Buttons in the Measure the tool function

The control offers the following options for writing the measured radius or length values into the tool table:

Meaning

Write basic values

The control transfers the values into columns R or L. The control resets existing delta values in columns DR or DL.

Write delta values

The control enters the delta values in columns DR or DL.

Tool measurement by scratching

The dimensions of an end mill can be determined by using the Tool measured function as follows:

    1. Select the Manual operating mode

    1. Set the workpiece preset if required
    2.  
      Tip

      Position the workpiece preset on the surfaces to be scratched in order to obtain a clear reference.

    1. Insert the tool to be measured
    2. Define the speed if required
    3. Start the tool spindle

    1. Select the Setup application

    1. Select the Measure tool probing function

    1. If necessary, check the values of the active preset or choose a different preset

    1. Scratch the workpiece in the desired axis direction (e.g., X+)

    1. Select the associated probing direction X+

    1. Select actual position capture
    2. The control transfers the actual X axis position into the Actual value column.
    3. The control shows the measurement results.

    1. Enter a Nominal value (e.g., 0)

    1. Select Write basic values
    2. The control transfers the value into column R of the tool table.
    3. The control resets the existing delta value in the DR column.
    4.  
      Tip

      When selecting Write delta values, the control will enter only one delta value in column DR.

    1. Scratch another axis direction if required (e.g., Z-)

    1. Select Exit probing
    2. The control closes the Measure tool probing function.
