2.12 Coordinate transformations (frames)
Workpiece coordinate system offset in the direction of the specified ge‐
ometry axis or axes
Workpiece coordinate system rotation:
● By linking individual rotations around the specified geometry axis or
axes
or
● Around the angle RPL=... in the current working plane
(G17/G18/G19)
Direction of rotation:
Rotation sequence: With RPY notation:
With Euler angle:
Range of values: The angles of rotation are only defined unam‐
biguously in the following ranges:
With RPY notation:
With Euler angle:
Workpiece coordinate system rotation by means of the specification of
solid angles
The orientation of a plane in space is defined unambiguously by speci‐
fying two solid angles. Therefore, up to two solid angles may be pro‐
grammed:
ROTS/AROTS X... Y... / Z... X... / Y... Z...
CROTS works in the same way as ROTS but refers to the valid frame in
the database.
Scaling in the direction of the specified geometry axis or axes to in‐
crease/reduce the size of a contour
Workpiece coordinate system mirroring by means of mirroring (direction
change) the specified geometry axis
Value: Freely selectable (in this case: "0")
