4.15.8 MK_WLK_VERWEILZEIT
This machine constant is used to automatically insert dwell times in the
correction module "SCHNEIDEN" ("CUT") at all places where the cutting tool
is to punch and cut. The MC has two parameters. The first entry defines the
dwell time after punching (M15/M16) and the second one the dwell time
after cutting. Both are entered in seconds with decimal positions.
4.15.9 MK_X_WINKEL
This machine constant defines an oblique coordinate system in the Z−X
plane. This is necessary, for example, for cylindrical grinding machines with
an oblique grinding wheel. This MC specifies to which extent the angle of the
X axis deviates from the perpendicular.
The display and in the parameter field always shows the tool tip in relation
to the tool in rectangular coordinates. With regard to X axis travel, a
difference must be made between path (G31) and route operation (G30).
While only X moves on the display in path operation, X and Z move on the
machine. The tool tip stops in relation to the tool in Z direction.
In route operation, the situation is the exact opposite. While only the X axis
moves on the machine, X and Z move on the display. The tool tip moves in Z
direction in relation to the workpiece.
)
Note!
When the X axis travels in route operation, the modal offset of
the Z axis (P160ff) is shifted. This corresponds an actual shift of
the NC coordinate system. If required, this shift can be undone
by means of a G121 and set it against the NC actual position
(P0ff).

4.15.10 MK_GEWINDE_VMAX
This machine constant limits the feed speed [mm/min] of the coupling axis
during thread grinding. For further information on the thread grinding
function, refer to "ETC Programmierung NC Betriebssystem" ("ETC
programming NC operating system") for G33.
