SINUMERIK 840D sl Operation/Programming ShopTurn (BAT) – 08/2005 Edition
After a new program is created and the program header is filled out,
define the individual machining steps in program blocks that are
necessary for finishing the workpiece.
A large amount of memory is available for one program.
However, depending on the storage space required, you can only
program a limited number of blocks.

ShopTurn on NCU (HMI Embedded)
You can program a maximum of 1,000 blocks using the "Straight"
function or a maximum of 600 blocks using the "Pocket" function.

PCU 50.3 (HMI Advanced)
You can program a maximum of 3500 blocks using the "Straight"
function or a maximum of 2100 blocks using the "Pocket" function.
You can only create the program blocks between the program header
and the program end. The following function groups are available to
you for programming:

Straight/Circle

Drilling

Turning

Contour turning

Milling

Contour milling

Transformations
Fill out an individual parameter screen form for each machining step.
Parameter entry is supported by various "help displays" that explain
the parameters.
The parameters tool, feedrate, speed, and machining are explained in
the following:
For each machining of the workpiece, you must program a tool. Tool
selection is done by name and is already integrated in all parameter
screen forms of the machining cycles with the exception of
straight/circle.
Once the tool is changed, the tool length offsets become active.
Tool selection is modal for straight/circle, i.e. if several machining
steps occur in succession using the same tool, then you only have to
program one tool for the first straight/circle.
