Select Recessing radial
Select the Expanded soft key
The cycle machines the number of recesses defined in Number
of recess cycles Qn . The Start point and End point contour
parameters define the first recess (position, recess depth and
recess width).
Cycle parameters:
X
,
Z
:
Start point
X1 , Z1 : Start point contour
X2 , Z2 : End point contour
B1
,
B2
:
-B cham./+B round.
(
B1
at contour start and
B2
at
contour end)
B > 0: Radius of rounding
B
< 0: Width of chamfer
A : Start angle (range: 0° <= A < 90°; default: 0°)
W : Final angle (range: 0° <= W < 90°; default: 0°)
R
:
Rounding
I , K : O-size X and Z
T : Tool number – turret pocket number
G14 : Tool change point
Further information: "Tool change point G14", Page 180
ID : ID no.
S
:
Cutting speed
or
Constant speed
F : Feed per revolution
P : Cut. width – infeeds <= P (no input: P = 0.8 * cutting width
of the tool)
ET
:
Recess depth
per infeed
EZ : Delay – Dwell time for chip breaking (default: length of time
for two revolutions)
Qn : Number of recess cycles (default: 1)
DX , DZ : Dist.to subsequent recess with respect to the
preceding recess
G47 : Safety clearance
Further information:
"Safety clearance G47", Page 180
MT
:
M after T
:
M
function that is executed after the tool call
T
MFS : M at beginning : M function that is executed at the
beginning of the machining step
MFE : M at end : M function that is executed at the end of the
machining step
