In general, milling keywords are available in turn/mill mode when a milling feature is being processed. The same thing is true for turning keywords. The following are some exceptions:
The milling keywords <CYCLE>, <PLANE>, <XY-PLANE>, <ZX-PLANE>, and <YZ-PLANE> are also available for turning features in turn/mill mode.
The turning keywords <SP-RANGE>, <F-UNITS>, and <RANGE-CH> are also available for milling features in turn/mill mode.
The milling keywords <X-VECTOR>, <Y-VECTOR>, and <USE-FIXTURE> are not available in turn/mill mode.
The turning keywords <X-VECTOR> and <Z-VECTOR> are not available in turn/mill mode.
When XBUILD is in the turn/mill mode, the Reserved Words dialog is color-coded to indicate the availability of the keywords.
