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.
