279 In the definition of a contour, a
contour pocket or a contour train,
you programmed a rounding arc
(RND, ISO: G25) with radius 0.
282 In the definition of a contour, a
contour pocket or a contour train,
you programmed a rounding arc
(RND, ISO: G25) immediately
behind a chamfer (CHF, ISO: G24)
block in the definition.
376 You programmed in sequence a
positioning block without radius
compensation, a rounding arc
(RND, ISO: G25), and a circle block
with radius compensation.
377 You programmed a corner radius
perpendicular to the working plane,
followed only by a movement in the
tool axis.
288 In the definition of a contour, a
contour pocket or a contour train,
you programmed a rounding arc
immediately before a CT (ISO: G6)
or CTP (ISO: G16) block in the
definition.
289 In the definition of a contour, a
contour pocket or a contour train,
you programmed a rounding arc
(RND, ISO: G25) as first NC block.
378 In the positioning block before
a rounding arc (RND, ISO: G25)
either you programmed a
movement only in the tool axis
or you used the M function M98
to cancel compensation.
510 You programmed a rounding arc
or chamfer that does not
immediately follow a positioning
block.
511 You programmed a rounding arc
or chamfer between tangential
contour transitions.
379 In the definition of a contour, a
contour pocket or a contour train,
you programmed a rounding arc
(RND, ISO: G25) with so large a
radius that it does not fit between
the adjoining elements.
380 In a rounding block approaching a
contour, the starting point of the
block lies inside the circle of the arc.
381 In a rounding block approaching
a contour the starting point of the
block lies too close to the center
of the rounding circle (less than
1.6 µm).
382 In a rounding block departing a
contour, the end point of the
departing block lies within the
rounding circle.
