Q244

ú

Set-up clearance Q200 (incremental value): Distance
between tool tip and workpiece surface.

ú

Depth Q201 (incremental value): Distance between
workpiece surface and bottom of slot

ú

Feed rate for milling Q207: Traversing speed of the
tool in mm/min while milling.

ú

Plunging depth Q202 (incremental value): Total extent
by which the tool is fed in the tool axis during a
reciprocating movement.

ú

Machining operation (0/1/2) Q215:
Define the extent of machining:
0: Roughing and finishing
1: Roughing only
2: Finishing only

ú

Workpiece SURFACE COORDINATE Q203 (absolute
value): Coordinate of the workpiece surface

ú

2nd set-up clearance Q204 (incremental value): Z
coordinate at which no collision between tool and
workpiece (clamping devices) can occur.

ú

Center in 1st axis Q216 (absolute value): Center of the
slot in the main axis of the working plane

ú

Center in 2nd axis Q217 (absolute value): Center of the
slot in the secondary axis of the working plane

ú

Pitch circle diameter Q244: Enter the diameter of the
pitch circle

ú

Second side length Q219: Enter the slot width. If you
enter a slot width that equals the tool diameter, the
TNC will carry out the roughing process only (slot
milling).

ú

Starting angle Q245 (absolute value): Enter the polar
angle of the starting point.

ú

Angular length Q248 (incremental value): Enter the
angular length of the slot
