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 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.
