Simulation»Construct Axis (Quest only)<br />
Note that, for QUEST at least, the stock axis represents one end of the kinematics chain. You<br />
cannot attach any other axis or entity to a stock axis. CERUN and GENER on the other hand allow<br />
stock fixtures and parts to be attached to a stock axis at run-time.<br />
Simulation»Construct Axis»Head Axis<br />
Creates a head axis, given an XYZ origin and head<br />
reference type. Head axes can define the location on the<br />
machine where exchangeable heads are mounted;<br />
positions on or around the machine where heads are<br />
stored when not in use; or anywhere else where heads<br />
might be attached. Parameters common to all axes (not<br />
listed below) can be found on page 96.<br />
� Head Socket: Specifies that this head axis defines<br />
the head control point (HCP) of the machine.<br />
The Socket ID should be set to 1 (one)<br />
for the main head control point of the machine.<br />
Other head ID‟s can be used if there are additional<br />
head mount points on the machine. The<br />
head axis ID to use for a given head can be selected in the model Load Tool Event macro.<br />
� Head Station: Specifies that this head axis defines a station in the head changer or some<br />
other holding area for head devices. A Station ID must be given to identify the station<br />
number. VM automatically moves heads in and out of stations during head change operations.<br />
Use the CERUN and GENER Simulation»Heads menu to assign heads to stations.<br />
� Other: Specifies a location where heads can be held. A typical use for this type of head<br />
axis is to define a position on a head change mechanism where heads are held while in<br />
transit. Heads can be attached or detached from an “other” axis type using the $FMSATA<br />
macro function.<br />
� Spindle definition: Select the “This head axis is connected to a spindle” check box if the<br />
head axis transmits the spindle force to attached head devices. This is common for the<br />
main head Socket. You would normally not select this for a Station or Other head axis<br />
type. VM uses the Spindle ID to differentiate between the different spindles that might<br />
be available on a machine. For mill/turn machines, use the Axes mapping tab page of the<br />
machine properties dialog to identify the spindle as milling or turning. For milling machines,<br />
the spindle ID should be 1 (one) for the main spindle of the machine. The choice<br />
of current active spindle can also be controlled using the $FMSMSP macro function.<br />
� Default head: Select the head device that will be attached to the head axis by default at<br />
the start of processing. This can be used to define the initial layout of heads at their predefined<br />
head stations if required. Changing the default head does not affect the current<br />
state of the model as shown in QUEST.<br />
� Currently loaded head: Use this to test the head processing of the model. Loading a<br />
head into a station will adjust the model navigator tree to show the selected head attached<br />
to the head axis. It will also draw the head at the head attachment axis. Only one head can<br />
be attached to a head axis at a time.<br />
