121 HEIDENHAIN TNC 310
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 First side length Q218 (value parallel to the main axis
of the working plane): Enter the length of the slot
ú Second side length Q219 (value parallel to the
secondary axis of the working plane): 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 Angle of rotation Q224 (absolute value): Angle by
which the entire slot is rotated. The center of rotation
lies in the center of the slot.
