2nd step
The area that was left out in the first step (shaded area in the
figure) is machined with the
Plunge longit. E
cycle. Before
executing this step, you must change tools.
The
expanded mode is used to machine the rounding arcs in the
contour valley.
The
Start point contour X1
,
Z1
and
End point contour X2
,
Z2
parameters determine the cutting and infeed directions—in this
example, external machining and infeed in negative X-axis direction.
The
Start point contour Z1 parameter was determined during
simulation of the first step.
Tool data:
Turning tool (for external machining)
TO = 3 – Tool orientation
A
= 93° – Tool angle
B = 55° – Point angle
