On a lathe where X-axis values can be output either in diameter or radius mode, the following commands can make the switch possible.
- MODE/DIAMET: selects diameter output for the X-axis, if supported on the machine
- MODE/RADIUS: selects radius output for the X-axis, if supported on the machine
The macro variable $XDIAM tracks the radius vs. diameter state of the X-axis output.
- This variable can be modified to change the representation mode of diameter vs. radius X-axis values
- The default state of this variable is the same as the default starting mode as defined in QUEST
- Set this variable to $FALSE for radius output and $TRUE for diameter output
- But using the variable to set the mode will not output the corresponding X-axis diameter / radius NC codes, unlike the MODE command
Benefit to user
- Helps the user to switch the X-axis output from diameter to radius or vice versa on a lathe machine
- One specific application is on a turn-mill machine where the X-axis values need to be in diameter mode for turning operations and in radius mode for milling operations
