Modify part program. If necessary, use another tool (ball end mill).
Clear alarm with NC START or RESET key and continue the program.
Channel %1 block %2 illegal tool orientation with 3D tool radius compensation
%1 = Channel number
%2 = Block number, label
This alarm can occur with 3D face milling: The angle between the surface normal vector
of the surface to be machined and the extremal surface normal vector of the tool surface
is smaller than the limit value given by the machine data 21080
CUTCOM_PARALLEL_ORI_LIMIT, or the tool is oriented such that machining would
have to be performed from the rear side of the surface. In this case, the extremal surface
normal vector is the vector whose direction deviates most from the direction in the tool
point (i.e. parallel to the tool longitudinal axis).
With cylindrical tools or tools which end in a cylindrical part (e.g. the standard torus milling
cutter), this vector is positioned perpendicular to the tool vector. For this type of tool, the
alarm indicates that the angle between the tool longitudinal axis of, for example a side line
of the cylinder, and the surface to be machined is smaller than the minimum permissible
value. With tools whose (valid) surface ends in a conical part instead of a cylindrical part
(e.g. a beveled cutter or a torus milling cutter where the torus is defined to be smaller than
90 degrees), this alarm indicates that the angle between a side line of the taper and the
surface to be machined is smaller than the minimum permissible value.

Channel %1 block %2 Illegal surface normal vector with 3D tool radius compensa-
tion
%1 = Channel number
%2 = Block number, label
In 3D face milling, surface normal vector and path tangent vector must theoretically be
perpendicular to one another, i.e. they must be at 90° to one another. Since both vectors
can be programmed independently of each other, deviations from this angle are possible
and allowed. This alarm is generated when the angle between surface normal vector and
path tangent vector becomes less than the limit angle given by the machine data 21084
