Convert linear traversing into splines (COMPCAD)
During the execution of the mold-making programs, the controller converts the linear traversing blocks into splines with the aid of the compressor (COMPCAD). This reduces the block change times and achieves faster data processing. The special functions from the 840D, such as separate jerk limitation for rapid traverse and feedrate as well as following error compensation through the integrated precontrol, are also implemented. The look-ahead functionality for the next 100 traversing blocks compensates for acceleration jumps, which improves the surface quality and the trueness of shape. The SINUMERIK 802D sl is also well equipped for the requirements of 3-axis mold making.
