Introduction

Especially within the context of mold-making machining, the entire CAD/CAM/CNC process
chain plays a major role in terms of ensuring optimum results on the machine.
The CAD system generates the geometry of the desired workpiece. Based on this geometry file,
the CAM system generates the corresponding machining strategy with the associated
technology information.
The data format output from the CAM system is generally an APT or CL data file. This is
converted into an executable NC code in the postprocessor.
The upstream postprocessor must support the programmable functions of the SINUMERIK
control in order to use the performance capability of SINUMERIK controls to the full.
The postprocessor should ensure that the higher-order functions of SINUMERIK controls (as
described in this section) are activated in the best possible way. An overview of all higher-order
SINUMERIK functions is provided in the following sections.
