6.6 Programmable scale factor (SCALE, ASCALE)
Function
With SCALE/ASCALE you can program scale factors for all path, synchronized axes and
positioning axes in the direction of the axis specified in each case. This enables the size of a
shape to be changed. You can thus program taking similar geometrical shapes or different
shrinkages into account.
Programming
SCALE X... Y... Z... (substituting instruction programmed in a separate NC block)
Or
ASCALE X... Y... Z... (additive instruction programmed in a separate NC block)
Parameters
SCALE,
ASCALE,
X Y Z
Deactivate scaling factor
For all axes: SCALE (without axis parameter). All frame components of the previously
programmed frame are reset.
Example of milling
With this workpiece, the two pockets occur twice, but in different sizes and at different angles
to each other. The machining sequence is stored in a subprogram.
252
Frame rotations with solid angles for spatial orientation of a plane
absolute, referred to the currently valid frame with set workpiece zero for
G54 to G599.
Frame rotations with solid angles for spatial orientation of a plane
additive, referred to the currently valid frame with set or programmed zero
point.
Frame rotations with solid angles for spatial orientation of a plane,
referred to the valid frame in the data management with rotation in the
specified axes.
A maximum of two solid angles may be specified.
Rotation in the plane: Angle through which the coordinate system is
rotated (plane set with G17-G19).
Absolute enlargement/reduction with reference to the currently valid
coordinate system set with G54 to G599
Additive enlargement/reduction with reference to the currently valid set or
programmed coordinate system
Scale factor in the direction of the specified geometry axis
