Beckhoff has adding two new functions and two technology packages to its TwinCAT 3 CNC software. TwinCAT 3 CNC Online Adaption offers TcCOM interfaces that integrate customer-specific modules for the online control of interpolation functions such as dynamic contour control to compensate for contour errors caused by physical deformation of the toolbox; a tool radius compensation function offers online compensation for factors such as the current tool radius, path position and path tangent; and a geometric feed rate adjustment is used to calculate a feed override factor to achieve a constant surface feed. TwinCAT 3 CNC Extended Interpolation enables two-path interpolation, allowing two independent contours to be described in a single NC channel. TwinCAT 3 CNC AM Plus makes programmed contour elements available to the PLC in advance and can be activated in the NC program or via the standard PLC interface. TwinCAT 3 CNC EDM Plus is a special technology package for wire-erosion and die-sinking EDM machines.
