Parameters

G90 Absolute dimension input, all data refers to the

actual workpiece zero

refers to the contour point last input

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

another block with G63 and the relevantdirection of spindle rotation

S Spindle speed

F Feed rate

M3 Direction of rotation right

M4 Direction of rotation left

Calculation of feed rate:

F = Spindle speed x Thread lead

For this function, you need a thread tap in the floating tapholder A spindle pulse encoder is not required

RP= Radius, distance between pole and target pointAP= Angle between path between pole and target

point and the angle reference axis (pole axisfirst named)

The pole (center point) can be defined in rectangular orpolar coordinates

When programming the circle, the pole is in the circlecenter point and RP corresponds to the circle radius

T Call tool number

D Call tool offset, activate tool length

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

G40 Deselection of cutter path compensationThe 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

NORM The tool travels directly along a straight line

and is perpendicular to the contour point.KONT The tool travels around the contour point in

accordance with

the programmed behavior at corners

G450/G451

For KONT: If start point and contour point are on one side

of a workpiece, the contour point is approached as withNORM directly along a straight line

Frame concept

For the three-dimensional description of the workpiececoordinate system, the following functions are available.TRANS/ATRANS Translation of the zero pointROT/AROT Rotation

SCALE/ASCALE Change of scale

Shift/rotate coordinates, TRANS/ROT

To switch off rotation: ROT (without specifying angle)

In all cases, the complete frame is deleted here!

TRANS Absolute* offset

* additive to a possibly activated selectableoffset (G54 – G59)

ATRANS (to a previously activated TRANS offset)

additive offset

X, Y, Z Coordinates of zero offset in axial directionROT Absolute rotation

AROT Additive rotation

X, Y, Z Coordinate axis about which rotation occurs in

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!

MIRROR Absolute mirroring

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)

SCALE New scale factor

ASCALE Additive scale factor

X, Y, Z Axes with scale factor in the direction of which

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
