Note:

• After the program has been interrupted (NC Stop), thetool can be moved away from the contour in themanual mode (jog) The control saves the coordinates

at the point of interruption

• Corrections are only possible in the blocks which havestill not been read-in by the control

Parameters

actual workpiece zero

You can change over from block to block as often as youwant between absolute and incremental data input

Within a block, you can also change the type of input forindividual axes by specifying AC for absolute coordinates or

IC for incremental coordinates

6 Tool Offsets and Compensation

Tool call

N10 T17 D8

compensation

In order that the tool offsets are correctly taken into account

in the axes, before the tool is called, the machining planemust be selected

Tool offset values can be exchanged in the course of the

NC run The machining plane does not have to be programmed

re-If no D number is to be input when the tool is called, a

D number can be specified via machine data

traversing direction left of the contour

traversing direction right of the contour

The tool length compensation acts automatically after tooloffset D has been called

In the NC block with G40/G41/G42, there must be at leastone axis programmed with the selected working plane (G17

to G19)

The CRC must be selected and de-selected in a

program block with G0 or G1

The offset acts only in the programmed working plane(G17 to G19)

In the NC block with G40/G41/G42, there must be at leastone axis programmed with the selected working plane (G17

to G19)

The compensation must be selected and deselected in aprogram block with G0 or G1 The compensation acts only

in the programmed working plane (G17 to G19)

angular degrees (positive sign = clockwise rotation)

Mirroring the coordinate axes, MIRROR

N10 MIRROR X0

Switch off MIRROR (without defining axis)

In all cases, the complete frame is deleted here!

AMIRROR Additive mirroring

X0, Y0, Z0 Address with value 0 of the axis at which

mirroring takes place

When mirroring on a coordinate axis, the control changes

• the sign of the mirrored coordinates,

• the direction of rotation for circulate interpolation, and

• the machining direction (G41/G42)

Increasing/reducing size of contour,

SCALE

N10 SCALE X2 Y2 Z2

Switch off SCALE (without defining axis)

In all cases, the complete frame is deleted here!

the contour is to be increased or reduced insize

If transformation follows with ATRANS, the offset values arealso scaled

Any contours that you wish to increase or reduce in size arebest defined in a subroutine

You can define an individual scale factor for each axis
