摘要: Five-axis machines with three translational and two rotation axes are becoming increasingly popular in serving the needs of mass production industry due to their ability handle geometrically complex workpieces using rotational axes. Theoretically, combination five offers a minimal number degrees freedom required transport tool into prescribed spatial position establish orientation. However, lead an inevitable nonlinearity tip trajectory so-called kinematics errors appearing specific machine. Eventually, one arrives at interesting question. Is it possible compensate this error by introducing additional axis? In other words, “does axis offer any optimization benefits sense above mentioned error?” paper, we answer question positively analyzing hypothetical six-axis milling machine on table tool. The sixth is build top existing five-axis MAHO600E Deckel Gildemeister. We present extension algorithm developed earlier authors for machining based optimal angle sequencing (the shortest path optimization). strategy use axis. leads increase accuracy, particular, rough milling. Numerical experiments cutting virtual built Vericut 5.0 validates results optimization. proposed procedure capable upgrading G-codes case
