1.2 Manual Control and Automatic Modes

Tool compensation in automatic mode

Tool compensation: Determine the compensation values referenced

to the current tilt angle of the B axis and the position angle of the tool.

The control converts the measured data into dimensions referenced to

the position B=0 and saves them in the tool database.

U Select “Comp > Tool compensation” in automatic

mode. The control opens the “Tool correct.” dialog

box.

U Enter the parameters and click OK to close the dialog

box.

U In the “Tool correct.” dialog box, the control indicates

the compensation values referenced to the B axis

angle specified in the previous dialog box.

U Enter the new compensation values.

In the “T” box (machine display), the control indicates the

compensation values referenced to the current B axis angle and the

tool position angle.

Additive compensation values are independent of the tool data.

The compensation values are effective in the X, Y and Z directions.

Tilting the B axis has no influence on additive compensation values.

 The CNC PILOT saves the tool compensation data in the

tool database, together with the other tool data.

 If the B axis is tilted, the CNC PILOT takes the tool

compensation data into account when calculating the

tool tip position.
