HEIDENHAIN CNC PILOT 4290 15

1.2 Manual Control and Automatic Modes

Changing the tool position: If the call refers to the active tool, the

slide moves to the tool change position and tilts the B axis or rotates

the tool to the position angle.

Offset position angle: With the “offset position angle” you can

position turning tools in the “normal” attitude or “upside down.”

When positioning the tool, the CNC PILOT also takes the basic setting

saved in the tool database into account (position angle = position angle

from the tool data + offset position angle).

Tool orientation: The CNC PILOT takes the orientation of the cutting

edge into account when calculating the position of the tool tip. The

control distinguishes between roughing, finishing and button tools as

well as recessing and threading tools (see figure).

Declaring magazine tools

If there is a tool in the machine's working space when the control is

switched off and on again, the tool needs to be redeclared. In the

corresponding dialog box, the CNC PILOT automatically suggests the

values in effect when the control was switched off.

U Select “T > Magazine > Manual tool” in manual

control mode. The control opens the “Magazine:

Manual tool” dialog box.

U Press the soft key, enter the B axis angle, check all

other parameters and click OK to close the dialog box.

The control loads the associated NC program.

U Activate the NC program with Cycle Start.

Note on operation and display: This function is executed

using an NC program. To activate the NC program, press
