10767 Channel %1 block %2 processing with tilt angle unequal 0 not possible
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: When face milling with a torus milling cutter, the tilt angle must be 0 if the surface normal vector and
the tool orientation include an angle that is less than the limiting angle given by the machine data
21082 CUTCOM_PLANE_ORI_LIMIT, i.e. in this case only the lead angle may be unequal to 0.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program. If necessary, use another tool (ball end mill).
Program Clear alarm with NC START or RESET key and continue the program.
Continuation:
10768 Channel %1 block %2 illegal tool orientation with 3D tool radius
compensation
Parameters: %1 = Channel number
%2 = Block number, label
Definitions: 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.
Reaction: Correction block is reorganized.
Local alarm reaction.
Interface signals are set.
Alarm display.
NC Stop on alarm at block end.
Remedy: Modify part program. If necessary, use another tool.
Program Clear alarm with NC START or RESET key and continue the program.
