A part program consists of a sequence of instructions to the NC
control. In its entirety, this sequence affects the production of a
specific workpiece or a particular machining process on a given blank.
A subprogram is a sequence of instructions in a part program which
can be called repeatedly with different defining parameters. Cycles
are a form of subprogram.
A workpiece is a part to be produced/machined by the machine
tool.
In the HMI, a workpiece is a directory in which programs and
other data for machining a particular workpiece are stored.
Cycles are subprograms for the execution of a recurring machining
process on the workpiece.
Programs are saved in the NC memory. The size of this memory is
dependent on settings made during start-up. (See Chapter 6 "Memory
info")
