Code 10768: [Channel %1: ] Block %2 illegal tool orientation with 3D tool radius compensation

Parameters: %1 = Channel number %2 = Block number, label Definitions: This alarm may occur during 3D face milling: the angle between the surface normal vector of the surface to be machined and the largest surface normal ve ctor of the tool surface is smaller than the limit value given by MD21080 $MC_CUTCOM_PARALLEL_ORI_LI MIT, or the tool is oriented such that machining would have to be performed from the rear side of the surface. In this case, the largest surface normal vector is the vector the direction of whic h deviates most from the direction in the tool point (i.e. parallel to the tool longitudinal axis). With cylindrical tools or tools whic h 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 an envelope line of the cylinder, and the surface to be machined is smaller than the minimum per missible value. With tools the (valid) surface of which 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 degr ees), this alarm indicates that the angle between an envelope line of the taper and the surface to be ma chined 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 Continuation: Clear alarm with NC ST ART or RESET key and continue the program.
