Crc/Tnrc With Combination Of Various Block Types And In Conjunction - Siemens SINUMERIK 880 Programming Manual

10 Cutter Radius Compensation (CRC), Tool Nose Radius Compensation (TNRC)
10.9 CRC/TNRC with combination of various block types and in conjunction with contour errors
10.9 CRC/TNRC with combination of various block types and in
conjunction with contour errors
When programming in compensation mode, special attention must be paid to the blocks
without tool movements in order to prevent contour errors:
• Blocks "without path"
Auxiliary functions, dwell time or a zero offset are programmed in the compensation plane
instead of paths.
• Blocks with "distance = 0"
Path addresses are programmed, but there is no movement since the distance is 0.
• Blocks "not in compensation plane"
Axis addresses outside the compensation plane are programmed.
Examples:
• One "auxiliary function block" between distances in the compensation plane.
