Mold&Die short description
2.1 Introduction
CAD -> CAM -> CNC process chain
Many CNC programs for freeform surface machining come from
CAM systems. The CAM system obtains the workpiece geometry
from a CAD system.
When executing CAM programs in the HSC range for Mold&Die, the
control has to process high feedrates with short NC/G1 blocks with
síngle points. The user expects good surface finish with great ac-
curacy in the µm range with high machining feedrates up to
10 m/min. By applying different machining strategies, the user can
„fine tune“ the program with the aid of Sinumerik application com-
mands.
When roughing, speed is the priority due to smoothing the contour.
When finishing, accuracy and surface quality is the priority.
In both cases, specifying a tolerance ensures that the machining
contour is observed in order to achieve the desired surface finish.
When defining the tolerance value for smoothing the contour, the
operator must have knowledge of the subsequent CAM program.
