E Tool width Width of grooving tool at cutting edge.( When "E__" is not
specified, P/S alarm will occur) Overlaps between each cutting in
grooving (proportion to the Tool width) are set to the parameter
9825.
* Q Cut amount
Infeed amount of the first cutting motion (When “Q___” is
not specified, P/S alarm will occur)
The parameter 9824 is used as the Return amount of pecking.
J rate of change of cut amount
Cut amount after the second cutting motion is decided as described
bellow ( When “J__” is not specified or J0 is specified, the cut
amount does not change) Unit:1%

When H1,”Bye-direction”, is specified as Cutting method, this
argument is not available.
* K minimum cut amount
The cut amount calculated as above is clamped
by this specified argument like the cut amount does not become
less than the argument amount. (When “K___” is not specified,
“minimum cut amount” is equal to zero)
When H1,”Bye-direction”, is specified as Cutting method, this
argument is not available.
R Dwell time
Dwell at the bottom of a groove in roughing. (When
"R___" is not specified, "Dwell time" is equal to zero) Unit : sec
* U Finishing allowance X
X direction amount of finishing.
* W Finishing allowance Z
Z direction amount of finishing.
(When "U___" and "W___" are not specified, Finishing allowance
is set to zero)
N Number of groove
Number of grooves when more than 0ne groove are to be
machined at regular intervals. (When "N__" is not specified,
Number of grooves is set to 1)
