GibbsCAM 2006 features various enhancements aimed at addressing the needs of production manufacturing, including programming tombstone-fixtured parts, multi-task machining machine tools and four- and five-axis simultaneous machining.   To enhance holemaking, the software includes Automated Feature Recognition (AFR) to support intersecting holes; Profiler circles that can be used as input to the hole manager; and improved hole processes, which support multiple retract levels and depths and fixture/clamp avoidance. An operations manager that provides a spreadsheet interface to sort and interact with large program files with large numbers of operation; HSM toolpath modification, which introduces arcs and feed rates changes to minimize the effect of direction changes in the tool path; enhanced toolholder support; and surface flow gouge checking are among the program’s noteworthy features.
