SMC_TRAFOF_Gantry2Tool1 (FB)ΒΆ
FUNCTION_BLOCK SMC_TRAFOF_Gantry2Tool1
Forward transformation for two-dimensional gantries (X/Y) with tool offset, i.e. with the tool axis differing from the z-axis. The tool is approximated by a line.
Note
For detailed information on transformations see Overview to SM_Trafo_POUs.
