Configuring cycles
22.6 Swiveling
Example:
MD18088 $MN_MM_NUM_TOOL_CARRIER = 4
Number of channels = 2
Assignment of the TO areas: MD28085 $MN_MM_LINK_TOA_UNIT= 2, this results in two
swivel data sets per channel.
Using angular tools
Angular tools are created and managed in the NC with tool type 130. The tool lengths are
entered in the tool of tool type 130. If an angular tool is also used on a swiveled machining
plane (CYCLE800), the basic tool orientation must be enabled with
MD18114 $MM_ENABLE_TOOL_ORIENT = 2. This enables a direction vector to be
transferred to the tool in the tool parameters $TC_DPV3[n] to $TC_DPV5[n]. The TOROT
(G17), TOROTY (G18), and TOROTX (G19) commands must be programmed for the tool
change so that the basic tool orientation is updated.

MD20126 is written to in CYCLE800
CYCLE800() corresponds to deselect toolholder (MD20126 = 0)
