Section 3
Defining of axis within a workspace
Explanation as per DIN 66217 or ISO 841:
Defining only three axes is however not enough in comparison with mod-
ern machine tools. For instance if the milling head of a milling machine is
to be swivelled by a certain angle or the quill of a tailstock is to be moved,
a further defining of these axes is required.
The DIN standard provides the following variants for such cases:
Here the rotational axes A/B/C
are associated with the X/Y/Z
axes.
Looking in the positive direc-
tion of the axis, the positive
direction of the rotation is
deemed to be clockwise.
The axes U/V/W are parallel to
the axes X/Y/Z
The positive direction is that of
the related main axis.
