When programming X and Y the new X-axis lies in the old ZX plane.

When programming Z and X the new Z-axis lies in the old YZ plane.

When programming Y and Z the new Y-axis lies in the old XY plane.

If the required coordinate system does not correspond to this basic setting, then an additional rotation must be

performed with AROT....

On programming the solid angles, they are converted into the equivalent RPY or Euler angles, depending on

machine data:

MD10600 $MN_FRAME_ANGLE_INPUT_MODE

These then appear also in the display.

Frame rotation in tool direction

With the language command TOFRAME, which also existed in older software versions, it is possible to define a

frame whose Z axis points in the tool direction.

An already programmed frame is then overwritten by a frame, which describes a pure rotation. Any zero offsets,

mirrorings or scalings existing in the previously active frame are deleted.

This response is sometimes interfering. It is often particularly practical to retain a zero offset, with which the

reference point in the workpiece is defined.

The language command TOROT is then also used. This command overwrites only the rotation component in the

programmed frame and leaves the remaining components unchanged. The rotation defined with TOROT is the

same as that defined with TOFRAME.

TOROT is, like TOFRAME, independent of the availability of an orientational toolholder. This language command is

also especially useful for 5-axis transformations.

The new language command TOROT ensures consistent programming with active orientational toolholders for

each kinematics type.

TOFRAME or TOROT defines frames whose Z direction points in the tool direction. This definition is suitable for

milling, where G17 is usually active. However, particularly with turning or, more generally, when G18 or G19 is

active, it is desirable that frames, which will be aligned on the X or Y axis, can be defined. As a result of this, the

G codes below are newly introduced into G code group 53:

These G codes enable corresponding frames to be defined. The functions of TOFRAME and TOFRAMEZ or of

TOROT and TOROTZ are identical to one another.
