HEIDENHAIN CNC PILOT 640 517
7.3 Tool data
Description of the tool parameters
 Identification number (ID): The CNC PILOT needs a unique name
for each tool. This "ID number" can have up to 16 alphanumeric
characters.
 Tool orientation (TO): From the tool orientation, the CNC PILOT
determines the position of the tool tip and, depending on the
selected tool type, additional information such as the tool angle
direction, reference-point position, etc. This information is
necessary, for example, for calculating the cutting radius
compensation, plunge angle, etc.
 The setting dimensions (XL, ZL) refer to the tool reference point.
The position of the reference point depends on the tool type (see
graphic support window).
 Compensation values (DX, DZ, DS) compensate for the wear of
the cutting edge. For recessing and button tools, DS stands for the
compensation value of the third side of the tool, which is away from
the tool reference point. The cycles automatically shift to the special
compensation. With G148, you can also switch to special
compensation DS for single-path machining operations.
 Direction of tool rotation (MD): If you define a direction of rotation,
a switching command (M3 or M4) is automatically generated for the
spindle or, with driven tools, for the auxiliary spindle in all cycles that
use this tool.
Parameters for drilling tools
DV Drill diameter
BW Drill angle: Point angle of the drill
AW Driven tool: This parameter specifies for drilling and tapping
tools during cycle programming whether switching
commands are generated for the spindle or the driven tool.
 0: Stationary tool
 1: Driven tool
NL Usable length
RW Angle of orientation: Deviation from the main machining
direction (input range: –90° to +90°)
AX Salient length in X
FH Chuck height
FD Diameter of the chuck
It depends on the PLC software of your machine whether
the generated switching commands are evaluated. If the
PLC does not execute the switching commands, they
should not be defined. Refer to your machine manual.
