Digitizing with a rotary axis

The digitizing feature supports rotary axes with cycle 18 LINE. The rotary
axis must be defined as a column axis.

Digitized data

The digitized data contains position information in the axes that are
identified in the RANGE cycle. A BLK FORM is not generated, since rotary
axes cannot be graphically simulated.

The display mode of the rotary axis (i.e. whether the display reduces the values to below 360° or not) must agree for
digitizing and for milling .

LINE cycle with a rotary axis

If you enter a linear axis (e.g. X) in the input param-
eter LINE DIRECTION the TNC moves the rotary
axis (e.g. A) entered in the RANGE cycle by the line
spacing L.SPAC as soon as it reaches the end of
the line.
