Fixed Cycles: Contour Pocket | TROCHOIDAL SLOT (Cycle 275, DIN/ISO: G275, software option 19)
Q202 Plunging depth? (incremental): Infeed per
cut; enter a value greater than 0. Input range 0 to
99999.9999
Q206 Feed rate for plunging?: Traversing speed
of the tool in mm/min while moving to depth.
Input range 0 to 99999.999, alternatively FAUTO,
FU, FZ
Q338 Infeed for finishing? (incremental):
Infeed in the spindle axis per finishing cut.
Q338=0: Finishing in one infeed. Input range 0 to
99999.9999
Q385 Finishing feed rate?: Traversing speed of
the tool in mm/min during side and floor finishing.
Input range 0 to 99999.999, alternatively FAUTO,
fu, FZ
Q200 Set-up clearance? (incremental): Distance
between tool tip and workpiece surface. Input
range 0 to 99999.9999; alternatively PREDEF
Q203 Workpiece surface coordinate? (absolute):
Coordinate of the workpiece surface. Input range
-99999.9999 to 99999.9999
Q204 2nd set-up clearance? (incremental):
Coordinate in the spindle axis at which no collision
between tool and workpiece (fixtures) can occur.
Input range 0 to 99999.9999
Q366 Plunging strategy (0/1/2)?: Type of plunging
strategy:
0
perpendicularly, regardless of the plunging angle
ANGLE defined in the tool table
1
2
plunging angle ANGLE for the active tool must be
defined as not equal to 0. The TNC will otherwise
display an error message
Alternatively
Q369 Finishing allowance for floor?
(incremental): Finishing allowance for the floor.
Input range 0 to 99999.9999
Q439 Feed rate reference (0-3)?: Specify what
the programmed feed rate refers to:
0: Feed rate with respect to the tool center point
path
1: Feed rate with respect to the tool edge, but only
during side finishing, otherwise with respect to
the tool center point path
2: Feed rate refers to the tool cutting edge during
side finishing
refers to the tool path center
3: Feed rate always refers to the cutting edge
