Reference machining
The reference machining cycle (registration of nominal values)
determines the maximum permissible torque and work of each
monitoring zone. These values are used as reference values!
CNC PILOT executes a reference machining cycle if:
„ There are no monitoring parameters
„ You select “yes” in the reference machining dialog box (after
program selection).
Activate the display:
U „Disp(lay) > select “load monitoring display”: the CNC PILOT
switches to the “Taking nominal values” submenu
“Taking nominal values” submenu:
„ “Curves” menu item
„ In curves 1 to 4 you assign the input field to the drives.
„ With “Display grid” you influence the accuracy of the depiction. A
small value increases the accuracy (values: 4, 9, 19, 39 seconds
per image).
„ “Mode” menu group
„ Line graphic: Shows the torque over the time axis.
„ Bar graphic: Shows the torque as a bar and indicates the peak
values.
„ Save/do not save measured values: The measured values must
be saved for later analysis of reference machining. Check the
setting in the “Save data” (“Write data”) display field.
„ Overwrite/do not overwrite limit values: Setting of whether
the limit values are overwritten when reference machining is run
again.
„ Pause: Stops the display
„ Continue: Resumes the display
„ Auto: Return to Automatic menu
Additional information during recording:
„ Zone number: Present monitoring zone
„ Negative algebraic sign: Production is not monitored (example:
skipping the paths of rapid traverse).
„ Tool: Active tool
„ Selected drives are listed and the current torque values are
displayed.
