5.4.4 ISetting actual values for grinding
The "Actual values grinding" function defines the dimensional relationship be-
tween the grinding wheel and a workpiece or the magnetic table. The workpiece
is probed with a dressed grinding wheel before the actual values are set. This is
a basic prerequisite of all automatic program cycles.
Activating setting actual values for grinding
• Press the "Actual values grinding" softkey in the softkey row on the right of
the "Machine Jung" screen.
• Enter an area (1 - 9) and press the "Select area" softkey. This area must be
the same as the machining area you selected on the main "Grinding pro-
gram" screen.
– This input selects the actual value system for grinding.
• Select either the "front" or the "back wheel edge" using one of the arrow keys
(see section 3.1 “Control unit” on page 47, position 8, 12, 14 or 18).
– This is the grinding wheel edge that is used to probe the workpiece. The pro-
gram is always calculated in relation to the front wheel edge.
• Then change to the input values area (various dressers are available as opti-
ons) by pressing the "END" key (tab key, see section 3.1 “Control unit” on
page 47, position D 17).
If you select the special " Multiple plunge grinding" program (see
section 5.5.14.1 “Special multiple plunge grinding program (optio-
nal))” on page 159) only the "front" wheel edge is active. It is activa-
ted automatically.
