Recessing, axial—expanded
Call the recessing cycles
Select axial recessing
Press the Expanded soft key
The cycle machines the number of recesses defined in number Qn. The
parameters for the contour starting point and end point of
contour
define the first recess (position, recess depth and recess
width).
Cycle parameters
X, Z
Starting point
X1, Z1 Contour starting point
X2, Z2 Contour end point
B1, B2 Chamfer/rounding arc (B1 contour start; B2 contour end)
 B>0: Rounding radius
 B<0: Chamfer width
A Starting angle (range: 0° <= A < 90°)
W End angle (range: 0° <= W < 90°)
R Rounding arc
I, K Oversize X, Z
G14 Tool change point (see page 128)
T Turret pocket number
ID Tool ID number
S Spindle speed/cutting speed
F Feed per revolution
P Recessing width: infeeds <= P (no input: P = 0.8 * cutting
width of the tool)
ET Recessing depth by which one cut is fed
EZ Dwell time for chip breaking (default: length of time for
two revolutions)
Qn Number of recess cycles (default: 1)
DX, DZ Distance to subsequent recess with respect to the
preceding recess
G47 Safety clearance (see page 128)
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
